Vector Instrument Operator Manual

1 Overview

Welcome to your new touchscreen instrument from Mecmesin. It has been developed using our Vector OS technology platform. For ease of understanding in this operating manual, all touchscreen products will be referred to as "Vector Instruments".

Marking a new era for handheld force and torque gauges, Vector Instruments utilise a 5" colour touchscreen featuring 10-point multi-touch inputs. This intuitive touch interface supports familiar gestures, including 'swipe' navigation, 'press-and-hold', and 'pinch/expand-to-zoom'.

Vector Instruments have an integrated microSD card expansion port, supporting compatible memory cards up to 32GB, for storing your important test measurement data and subsequent easy transfer of data to a device of your choice.

Some functionality described here may not be available on your instrument.  Please see the release change logs at the end of this manual.  Your device is upgradeable and so by upgrading to the latest release you are ensured the best possible user experience.

1.5 If your Vector Instrument becomes unresponsive

In the unlikely event that your Vector Instrument becomes unresponsive, please contact your local representative or Mecmesin Technical Support (support@mecmesin.com).

1.6 MicroSD storage

Your Vector Instrument supports microSD cards up to 32 GB. Unformatted cards will be automatically formatted. MicroSD cards of a higher capacity will not be recognised by the instrument.

1.7 About lithium-ion batteries

Your Vector Instrument uses lithium-ion batteries as its power source. These are commonly used in many devices around the world but there are rules about how to transport them or dispose of them. Please check with your local representative before disposing of the Vector Instrument or its battery.

When returning your Vector Instrument to Mecmesin please follow the guidelines for your territory. Packages containing Vector Instruments must be labelled appropriately. Your territory may have specific requirements when it comes to domestic and international shipping of devices containing lithium-ion batteries. It is important that you familiarise yourself with these requirements before shipping any Vector Instruments to customers, or back to Mecmesin for repair/service/calibration.

If a Vector Instrument becomes faulty and needs to be returned to Mecmesin for repair then it is vital—before shipping it back—that it is established whether or not a faulty battery is responsible for the failure of the device. If it is suspected that the battery is faulty then it must be removed from the device and disposed of locally. Contact your local representative for advice.

1.8 Charging the battery

Vector Instruments are supplied with a partial charge in the Lithium-Ion battery. We recommend fully charging the battery of your device before use.

Mecmesin recommends a 'fast charge' USB-C charger (such as the one provided) be plugged into mains power and be used to charge Vector Instruments for maximum efficiency.

Other chargers may be used, but we cannot guarantee the rate of charge achieved in these circumstances.

Portable power banks can also be used to charge/extend the battery life of the device in situations where you may need to use Vector Instruments in remote areas.

1.8.1 The first few times you charge your Vector Instrument - Learning mode

In order to provide accurate battery charge levels, your Vector Instrument needs to 'learn' the battery behaviour.  It does this during the first few charge cycles and during this time, the battery icon is shown as amber.  During this time you see some unusual battery level display behaviour such as jumping from 90% to 99% or remaining at 99% for a long time.  This is normal.  If the behaviour persists for more than 5-10 charge cycles then please contact support@mecmesin.com.

1.8.2 "My battery does not appear to charge"

Sometimes, if a battery becomes depleted it can read 0% even when charging—this can go on for up to 30 minutes before a charge is registered on the instrument.

1.8.3 "When I plug in my Instrument to a charger or my PC I see a popup with a big red flash on it"

Your Vector Instrument uses a relatively high power battery.  This means that it needs a high power charger to provide the instrument with a net popsitive charge.  If the power supply you plug into is not designated "PD" then the instrument will show you the popup to tell you that there is not enough power in the supply to charge your device.  Just touch the popup to clear it.

1.8.4 "My battery has been charging for several hours but the charge level is showing <100%"

There are two possible reasons for this:  Some early instruments had an issue where the battery, even though fully charged, would not show 100% on the instrument - usually the charge value would stop at around 87% or 93%.  To resolve this, update your firmware to the latest release (see Software Updates).  In later versions, we implemented a learning algorithm that analyses the battery during the first few charge cycles.  While this ultimately results in a more accurate battery charge level, during the learning stage the charge level can seem to be at 99% for a long time, and during discharge can seem a bit erratic.  This needs no intervention and will settle down as the learning stage progresses.

1.8.5 "Can I charge my Vector Instrument from a computer's USB port?"

Connected to a computer USB port the instrument's battery will be trickle charged.  However, the power output of a computer USB port is too low to provide a 'net positive' charge to the instrument's battery whilst the instrument is being used, but it will partially extend the battery life.

1.8.6 "Can I charge my Vector Instrument using a power bank?"

Portable power banks can be used to charge/extend the battery life of the device in remote areas.  Performance will depend on the power bank used.

2 Software updates

Vector Instruments (including the VFG, VFTI and VTG Tornado) are powered by our technology platform, Vector OS.  At the time of writing, the production version was 1.0.8.0

Your instrument is supplied with the latest version of Vector OS software pre-installed, so will not require updating until a new version becomes available.

Your instrument is upgradeable (within the constraints of the installed hardware) and regular Vector OS updates will be issued for downloading to your device. Vector OS is in continuous development and open to feature requests—please contact us if there is a feature or function that would make the instrument(s) more effective for you.  Delivery of feature requests will depend on the workload and priorities of the development team.

2.1 Vector Instrument Programmer (VIP)

4.1 Surface features and connectors

1	External 1 and 2: These are serial I/O ports and can be used by Vector Force & Torque 'Smart' Adaptor, MultiTest-dV connect, serial printer.
2	USB-C port: This is used for charging the internal battery and for software updates.
3	Secure Digital (SD) card storage: microSD cards up to 32 GB are accepted. This is used for storing measurement raw data, statistical data (results only) and uploading data to the device (firmware updates, new configurations, etc.).
4	Power button: Hold for approx. 3 seconds to switch on or off.
5	9-way D-Type connector for data communication and footswitch operation. VTG Only.

It is recommended that the protective rubber covers be used whenever possible to avoid dust ingress. Also, although Vector Instruments are very robust, they are not indestructible and so we also recommend that the rubber perimeter bumper provided is used at all times.

 

5 External Inputs EXT1 and EXT 2 (VFG/VFTI only)

These ports are identical and may be used for the same purposes.  With the correct corresponding cable (see "Use of Peripherals", above) they can be used to:

• connect to your Mecmesin-dV test stand
• connect to serial printers
• connect to external sensors (via an adapter box)
• connect to a PC serial port

5.1 MultiTest-dV connection

When connected to a MultiTest-dV test stand, the VFG/VFTI force or torque value is passed to the test stand.  Simple pre-configured test methods can be executed by the dV test stand either as a stand-alone system or in conjunction with VectorPro Lite software.  All data collection functions of the VFG are unaffected and the statistics mode of the VFG can be used, although at the time of writing there is no corresponding compatible statistics mode with VectorPro Lite.

5.1.0.1 Connecting a VFG to a MultiTest-dV motorised test stand

For this, you will require the correct interface cable(s) and your MultiTest-dV must be installed with Firmware release 3.1.4.0 or later. Please contact your local Mecmesin representative if you need assistance.

When the VFG is successfully connected to your MultiTest-dV test stand, the TEST STAND CONNECTED icon will show in the status bar.

5.1.0.2 Connecting a VFTI to a Vortex-dV motorised torque stand

For this, you will require the correct interface cable(s) and your Vortex-dV must be installed with Firmware release 3.1.4.0 or later. Please contact your local Mecmesin representative if you need assistance.

When the VFG is successfully connected to your MultiTest-dV test stand, the TEST STAND CONNECTED icon will show in the status bar.

While connected to your MultiTest-dV or your PC running VectorPro Lite, your system will treat the VFG/VFTI/VTG the same as an older AFG/AFTI or Tornado.

5.1.1 External sensors

When used with a 'Smart' Load Cell Adapter (Mecmesin part number 874-005), the VFG and VFTI are fully compatible with the Mecmesin 'Smart' sensor range.  When an external sensor is connected, the primary sensor display will show the external sensor, regardless of whether or not there is an internal sensor present.

5.1.2 MultiTest-dV Test control

Unlike the AFG, the Vector Instruments do not have any test stand control features.  These have been entirely delegated to the MultiTest-dV test stand and can be accessed via the Test Edit menu on the dV front panel.  See your MultiTest-dV manual for details.  This in no way affects operation of the MultiTest-dV with an AFG.

5.2 Serial Communications

5.2.1 Serial port settings

Your Vector Instrument serial port settings are defaulted to:

Baud Rate: 115200 (to match MultiTest/Vortex-dV settings) configurable from 9600 to 921600

Stop bit: 1

Parity bit: None

Carriage return: on

Line Feed: on

5.2.2 Print or transmit data to PC or printer

Printing and serial transmit are both instigated by the PRINT icon  or the legacy TXD/AFG icon . When you touch the icon, the current values shown in the primary sensor display are printed. If Print is selected from the statistics display then the table of values and results is printed or transmitted.

5.2.3 Serial printer connection

Your serial printer will connect to one of the two EXT ports at the top of the VFG, or to the 9-way D-type connector of the VTG.  Connection is confirmed by the serial icon in the status bar.  When connected to a serial printer, the Print icon will send data to the printer in the format determined by the printer settings on the Vector Instrument.

5.2.4 PC serial connection

When connected to your PC serial port, data from the Vector Instrument may be sent directly to a PC.  Printer settings are enabled for this mode, so the settings as configured in Printer Settings on the Vector Instrument affect PC serial data.

5.2.5 AFG serial protocol

The AFG serial protocol has been implemented, where appropriate, in your Vector Instrument so that if you are used to this workflow with older instruments then you can continue working in the same way with your Vector Instrument.

7.5 Break Detection - how it works

There is a simple break detection mechanism included in your Vector Instrument.  It takes the parameters of low force threshold, % drop and a time window to calculate an approximate break point in your test data.

These parameters can be configured in the Sensor settings page as described above.

If the time window is set to 0.0s, then the window is undefined and break will be detected when the %drop is registered no matter how long it takes.

The Break Detect can be tied to the overload channel so that when used in conjunction with a MultiTest-dV test stand the break detect can instruct the test stand to stop the test. It can also be configured to make an audible sound upon detection of a break.

7.5.1 Mapping Break to the Overload channel

The Break event can be mapped to the overload channel by selecting .  This does not register an overload on the device or show the overload icon, but when the instrument is used as the sensor in a MulitiTest-dV system, this has the advantage of commanding the test to stop when the designated state is registered.

7.5.2 Mapping Break to Audio

You can choose to play the alert sound when a Break is detected by selecting

7.6 Alarm settings

In V1.0.8.0 the Alarm settings were separated out into their own settings page.  Previous versions had the alarm settings as part of the sensor settings page. On this page, you can set the low, high and pre-alarm values.  You can also choose whether or not to use these values to determine PASS/FAIL. 

The band between the pre-alarm and alarm can be designated to PASS or FAIL. If this band is set to register a PASS, a popup will appear showing the PASS/FAIL state and asking whether to print or to remove the popup.  Taring the display will clear the PASS/FAIL state.

On the settings page, the configurable alarms are shown in the order in which they are actioned, from high alarm down to low alarm.

High alarm - this can be tied to the overload channel and also be configured to sound the annunciator

High pre-alarm - this can be tied to the overload channel and also be configured to sound the annunciator

Low pre-alarm - this can be tied to the overload channel and also be configured to sound the annunciator

Low alarm - this can be tied to the overload channel and also be configured to sound the annunciator

Choose whether or not to report PASS/FAIL and whether or not to designate the band between pre-alarm and alarm as PASS or FAIL—this can be tied to the overload channel and also be configured to sound the annunciator.

7.6.1 PASS/FAIL

The alarms may be configured to determine a PASS or FAIL condition as follows.  This is switched on or off in the Sensor Settings as described previously in this manual.

7.6.2 Mapping alarm states to the Overload channel

Each of the alarm states along with the PASS/FAIL state can be mapped to the overload channel by selecting .  This does not register an overload on the device or show the overload icon, but when the instrument is used as the sensor in a MulitiTest-dV system, this has the advantage of commanding the test to stop when the designated state is registered.

7.6.3 Mapping alarm states to sound

You can choose to play the alert sound when each alarm state has been reached by selecting

7.12 Save configuration

 

Your Vector Instrument allows you to save up to 7 different configurations, which can be loaded directly to the instrument.  This can be used to save setups for different users, or perhaps where different alarm settings are used for different samples etc.

If you want to save the current configuration of your device select an available configuration ID.

7.13 Load Configuration settings

If there are saved configurations available then this settings page enables you to select one for loading onto your instrument,  Simply select the configuration ID  and confirm when prompted.

7.14 Device Management settings

Here you can perform some high-level functions, including:

Save all information pages to microSD card

Reset to Factory defaults

Update sensor firmware (if one is available)

7.15 Security settings

You can set a 6-digit passkey to restrict access to some, or all, of the available settings.  By touching the Lock/Unlock icon on each individual settings page, or at the top of the Device Settings page, you can control access to different aspects of the Vector Instrument configuration.  When trying to unlock any one of those locked settings the passkey must be entered first.

7.15.1 Passkey first-time set

The passkey is set by default to 000000. To set the passkey, touch the Unlock icon:

Unlock

This will show the passkey as ******.  Touch on this and you can then enter a 6-digit number.  When finished, touch accept and your new passkey is set.

7.15.2 Passkey change and subsequent use

To access the passkey setting page you must enter the existing passkey.

8 How-to guides

8.1 Power ON / OFF

To power the device on it needs to have some charge in the battery. 

In compliance with shipping regulations, to avoid any chance of accidental power-on during shipping, the device will auto power OFF if the power button is held for more than 5 seconds.

To power the device ON:  Press the power button and hold until the Vector logo is displayed, then you can let go.  The device should power on to a live measurement display.

If the device is charging at the time of powering on, the Vector logo may only be shown very briefly, or in some cases not at all.  In this case, the device will power on directly to the main display.

To power the device OFF: Press and hold the power button until the main display turns off.  If the device is charging, the charge status display will be shown for a few seconds before the display powers down.

8.2 Check charge status while charging

If the device is powered OFF and you want to see the charge status while it is charging, simply press the power button once and the current charge status will be displayed for 5 seconds.

8.3 Reset to Factory Settings

If you want to revert to factory defaults, go to the Device Settings page and select the "reset" option.

  Device Management settings

  Reset to Factory Settings

8.4 Show instrument information

To view your instrument information, activate the Information toolbar by touching the Information bar, and selecting the 'Device Info' icon (pictured left).

Information displayed includes:

• firmware (FW) version of Vector OS
• hardware version of your instrument
• Mecmesin serial number of your instrument
• a Universally Unique Identifier (UUID) for diagnostic purposes

 

8.5 Show sensor information

To show information about the sensor currently connected to your Vector Instrument, touch and hold the sensor display to activate the sensor toolbar.

Scroll to find and select the Sensor info icon.

Information displayed includes:

• Device name
• firmware version
• hardware version
• SENSOR serial number - this is different to the Instrument serial number
• last calibration
• calibration due date
• max and min load encountered

There are also four buttons displayed that allow the following:

 Display overload details:  This will show all overloads encountered by the sensor.  This is a permanent record and cannot be cleared.

 Save Sensor information to the microSD card

 Update Sensor firmware - if a more recent version of sensor firmware is available then it can be updated using this option

 Check sensor.  This runs a routine that will measure the mV baseline of the sensor and also activate precision shunt resistors in the compression and tension arms of the load cell bridge circuit.

Four values are displayed once the check is complete:

• mV baseline of the sensor
• % change since the last check
• compression shunt deviation from nominal
• tension shunt devitation from nominal

The expectation is that the shunt values would be within the design specification of the instrument.

8.6 Show microSD Card Information

If a microSD card is currently fitted into your Vector Instrument, select the microSD card toolbar by touching and holding the status bar.

Select the Info icon

Information displayed includes:

• Total capacity
• Available storage space
• Manufacturer and microSD card details

8.7 Store Device Diagnostic information to the microSD card

In requesting product support from support@mecmesin.com you may be asked to share the instrument diagnostics with us.  You can store all information pages - Instrument, Sensor, SD card, and all device settings - to the SD card by accessing the Device Management settings page  and choosing "export device information" .

You can then share the resulting file with your support Engineer.

8.8 Freeze (Pause) the Display

 To freeze or pause the display, place the Freeze button  onto the main button bar. To freeze, touch the button and again to unfreeze. Measurement is suspended while the display is frozen.

8.9 Transmit or Print a single Maximum value only

Sometimes, it's useful to only transmit the last recorded Maximum value.  There are two ways to do this with your Vector Instrument. 

8.9.1 AFG Emulation method

Place the MAX/AFG emulation button on your button bar.

Touching this button cycles through MAXC (Max compression), MAXT (Max Tension), MAXD (Dual Max) for VFG with corresponding descriptors for VTG Tornado.

With this option selected, when Print  or TXD/AFG is selected, only the value specified is transmitted or printed.

8.9.2 Live reading method

Selecting Print or TXD/AFG will transmit the value displayed in the main reading. If the main reading is changed to show either Maximum value, then that value will be transmitted or printed.

8.10 Select Operating Mode

The Vector instrument is set to Break Detect mode by default, but can be configured to one of three operating modes, and the operating mode determines what is shown in the sensor display panel:

• Break detect (Maximum Tension/clockwise, Live reading and Maximum Compression/anti-clockwise)
• Dual Peak (First Peak, Live Reading, Second Peak)
• Average over time (Maximum Tension/clockwise, Running Average - while the algorithm is active (see below) - and Maximum Compression/anti-clockwise)

To change the operating mode, Go to the Device settings page, select Sensor Settings and the Operating Mode. 

 

8.10.1 Break Detect Mode

In this mode, the instrument will detect a break depending on three parameters:

1. When the applied load exceeds a threshold value, then ...
2. drops by a percentage of applied load, and...
3. within a certain time.

Low break threshold: can be any value between 1% and 25% of load cell capacity.

% drop required to detect a break. Any value between 5% and 95% of applied force

Time window within which break will be detected. Any value between 0 and 5 seconds.

8.10.2 Dual Peak Mode

In dual peak mode, the break detect parameters are used to detect peaks rather than break where the % drop and time window are used to define a peak where the load drops by the given value on either side of a maximum within the time window defined.  The same range constraints apply for the algithm parameters as for break mode.

Selecting this mode automatically configured the main sensor values display to show:

• TOP: 1st peak
• MIDDLE: Live reading
• BOTTOM: 2nd peak

8.10.3 Average Over Time Mode (v1.0.7.0 and later)

Selecting this mode automatically configures the main sensor display values to show:

• TOP: Max Tension
• MIDDLE: Running average during measurement
• BOTTOM: Max Compression

In this mode the instrument uses four parameters to determine how the function operates.  All four parameters are found under Sensor settings when Average over Time Mode is selected.:

•  Start Force Threshold:  This value is used as the threshold value to start averaging.
•  Stop Force Threshold:  This value is used to determine when averaging should stop when no duration timer is set, or to stop averaging before the elapsed time is reached.
•  Start delay time (s): Configured in Sensor Settings.
  • Once the minimum threshold has been exceeded, the start delay timer is started.
  • Once the start delay time has elapsed, averaging begins.
•  Duration(s):  Configured in Sensor Settings.  Once averaging has started, the duration timer begins and once the duration has elapsed averaging stops. See example below for what happens if the timers are set to zero:

 

8.10.3.1 Setting the timers to 0

Setting either of the timers to 0 seconds disables them. If the start delay is 0, averaging starts immediately after the threshold is exceeded.  If the duration is set to 0, averaging continues until the load value drops below the threshold.

8.10.3.2 Main Display

The main display will show the Av/T icon to show that the mode is selected.

During averaging a second timer is displayed to show elapsed time.

While the averaging is active, the main display value shows the running average, not the live load.  Once the averaging time has elapsed or once the load drops below the threshold, the resulting average is shown.

8.11 Apply a multiplication factor

 Under the Sensor Settings page, you can specify a multiplication factor  that will then be applied to the live reading.

If a factor is specified within the sensor settings page, then the live display reading and associated peaks, maxima, minima, etc will be multiplied by that factor.

Any number between 0.1 and 10 may be specified.

When a multiplication factor other than 1.000 is set, the units of measurement will be overlaid with an "X" symbol showing that the reading is modified.

8.12 Perform Tests when used with a MultiTest-dV or Vortex-dV

With previous Mecmesin instruments (AFG/AFTI), there were limited test controls that were available from the instrument when connected to a compatible MultiTest or Vortex test stand.  These would command the test stand to stop, reverse, cycle, etc., as appropriate. 

When using a Vector Instrument (VFG/VFTI), all controlled testing with the gauge / test stand system is now delegated to the test stand, and all test parameters are set from its front panel.

8.13 Adjustment and calibration

Calibration adjustment of a Vector Instrument is accessed via the sensor toolbar menu. It is protected from unauthorised use.

Adjustment and calibration can only be performed by an authorised representative of Mecmesin/PPT Group. Please contact Mecmesin to become an authorised representative for calibration.

Calibration can be performed by applying the desired force to the instrument and recording the live reading, useful for checks between calibration periods. The instrument 'calibration date' and 'calibration due date' can only be reset after calibration by an authorised representative of Mecmesin/PPT Group.

8.14 Set date and time

Enter the Device Settings menu either from the Information toolbar or by swiping across the main display (from left-to-right).

Select the Time/Date icon

Enter your local standard time and activate the Daylight Savings toggle if required.

1	Current Time
2	Current date
3	Calendar format toggle (switches between dd/mm/yy to mm/dd/yy)
4	Daylight Savings toggle (switches between ±1hr)

8.15 Configure the Main Functions Bar

The right-hand three buttons can be configured to show icons of your choice.

Either swipe right from the Main display or touch the Device Settings icon from the information toolbar.

Select Display settings:

Select the buttons of your choice for the three available buttons:

8.16 Make and record a measurement

You can record/save tests measurements using the Record icon

The Record icon is found in the Graph toolbar or you can configure one of the four function/shortcut icons to include the Record icon.

 

8.17 Recall the last recorded test/measurement

To recall the last saved test, activate the microSD card toolbar and select the “last test/live view” toggle icon:

8.18 Recall all stored (microSD card) tests/measurements

To select any previously recorded test, activate the microSD card toolbar and select the folder icon:

Use the arrow keys to select the test to review.

8.19 Export Data

Every test is stored on the microSD card in two formats:  Raw and .csv.  Raw format is unique to the Vector Instrument.  The .csv file holds the test data in a format that is able to be opened directly by Microsoft Excel (R) .  The file name includes the date and time.

When the file is opened in Excel there is a header that accompanies the data with the following information:

• Log_ID_Number and Sensor_Number are internal system parameters
• Date_and_Time is the date and time, according to the Instrument, when the data was collected.
• Gauge_Serial_Number is the serial number allocated by Mecmesin before shipping. This can be found on the back of the Vector Instrument.
• Gauge_FW_Version version is the firmware used at the time of collecting the data
• Sensor_Serial_Number and Sensor_FW_Version numbers are those that belong to the sensor in use at the time of collecting the data
• Sensor_Calibration_Date shows the date and time of the last official calibration
• Sensor_Dimension is the units of measurement as configured when the data was collected

Column headers are time in microseconds and system units of millinewtons. These are not configurable.

8.20 Perform a series of measurements to obtain a statistical set

Before and after collecting readings for a statistical set.

8.21 Using your VFG as a Shotcrete Penetrometer

If you purchased your VFG as part of the Shotcrete Penetrometer product bundle then the VFG will have been pre-configured from the factory to the settings below.

Otherwise, the VFG can be configured to collect statistics in the units of Shotcrete Penetrometry as defined in test standard EN14488-2.  To do so requires the use of specific probe attachments - for example, Mecmesin part #432-519 (pictured below):

The following steps provide the optimum configuration for shotcrete penetrometry.

8.21.1 Units settings

Newtons - If DaN (DekaNewtons) are required, then set the X factor in the Sensor settings to 0.1.

8.21.2 Sensor settings

	30 N
	90%
	0.5 s
	If DaN are required, set X-factor to 0.1

8.21.3 Statistics settings

The Penetrometer mode setting enables the instrument to automatically convert the statistical set of measured force data into the compressive strength value in MPa, based on the selected aggregate size.
