For more information
Whenever you update the configuration of your machine by adding or removing a component, you must also update the configuration in the MFT software.
You only need to do this if any components have been replaced since the last update.
Suspensions are not components that require configuration updates.
The load range of your cell should be written on the latest sensor calibration certificate or directly on the load cell.
If a label is missing, the unit calibration values will be non-round but close to the specified unit range.
ex: Fx: 214,56N → Unit range is 200N.
Ts: 24.56 Nm → Unit range is 24 Nm.

Add Steps
Add a Standard Step
For more information
Principle of the STANDARD Step:
A standard step can combine multiple axis and module activations, such as applying a force (Z stage), enabling motion (Drive function), and heating the sample (Temperature function for chambers).
During this combinated step, the force is first applied and stabilized. Then, if a heating chamber is used, the defined temperature is reached. Finally, the drive type of motion drive is activated and the duration starts.(unless the engage parameters are modified).
Part 1: Duration
Duration of the step
In this window you can control the duration of the step.
The highlighted button allows the user to automatically calculate the duration of the step if the parameters selected offers to do so with a defined duration of a single repetition and certain number of repetitions (Slide for example)
By default, the logging and time duration start after the force is reached. (see Waiting for force/temperature to settle further)
Part 2: Reset
In this window you can reset the value of Fx at the beginning of the step. If it is unchecked, the Fx value will not be subjected to any reset.
This option is necessary to be pressed only when there is an offset of the Fx value at the beginning of the test (1D+1D arm), it will create issues in most cases when using a 2D Load Cell.
Part 3: Data Logging
Checking “Log during this step” will record the test data during the step. If it remains unchecked, no data will be logged for this step.
In case the user wants to divide the data logging into smaller periods, he can modify the values of “Log Period” and “Log Interval”.
- Log period (seconds): The duration of the log period.
- Log Interval (seconds): The duration of the interval between 2 log periods.
Part 4: Force
The Z-Axis will reach out for a contact when applying a constant force of 0 N as opposed to the undefined option.
Each force are defined for each step, this aspect must be taken in consideration, meaning that the same force must be defined each step to keep applying the desired force throughout the run-test.
Tracking : Adjusting the reaction time
- Click the drop-down menu and select Standard.
- Click ADD a new step.
- Define the duration of the step in the DURATION Section.
- Define a constant or linear force within the range of the sensors and suspension.
- Press ENTER.
Remember to define values below the limits of your load cell and suspension.
(Refer to the load cell manual, suspension section for help)
Activate the Drive
For more information
Drive motion
The action type might change based on the drive selected.
- Idle: If this action is selected, the drive doesn’t move during this step.
- Cycle: Oscillates the drive in counter and clockwise directions.
- Revolution: Number of revolutions before it changes direction.
- Velocity (rpm): Final velocity of displacement after the acceleration phase.
- Acceleration (s): Acceleration phase duration.
If the number of revolutions entered is below 1, the rotary drive will realize a reciprocating-like rotary movement.
- Slide: Moves the drive for a fixed number of revolutions.
- Revolution: Number of revolutions to be realized.
- Velocity (rpm/Hz): Final velocity of displacement after the acceleration phase.
- Acceleration (s): Acceleration phase duration.
- Continuous: Moves the drive at constant velocity in counter or clockwise direction.
- Direction: CW for clockwise, CCW for counterclockwise direction.
- Velocity (rpm/Hz): Final velocity of displacement after the acceleration phase.
- Acceleration (s): Acceleration phase duration.
- Move to Angle: Moves the drive to a nominal angle of the shaft
- In the same Standard Step, click on DRIVE.
- Click on Idle to unroll the list.
- Select Continous.
- Insert the Velocity.
Ex: 500 Rpm or 10hz
- Insert Acceleration and Deceleration time (or leave default).
Ex: 5s
Introduce the components
For more information
The maximum sampling rate of the system is 10kHz. Default is 1kHz.
You have the possibility of changing the Sampling Rate (Hz) and number of data points averaged.
- Sampling rate: It corresponds to the amount of data points taken in each second. The higher it is, the bigger the resulting file will be.
- Averaging: This number is used for the moving average filter. It corresponds to the number of data points averaged for each point recorded in the final file. The higher this number, the less the variations will be seen in the results.
Saving the data as part of a project.
First, click on “ Project Folder” to select the storage location of the project.
Then, in “Sample Name [Subfolder]”, it is possible to create a subfolder where all the tests of a specific sample are stored.
Finally, in “File name: Run-XXX-“, you can change the increment for every specific test of a sample.

All the recipes that have been authorized in the Expert Mode will be displayed here.
Machine manual control
Machine manual control allows the user to manually control the displacement of the X, Y, Z stage and the module installed.
For X, Y and Z, the 2 first buttons move the axis in the direction of the button whenever pressed. The last button (“Distance”) allows the user to move the axis by a specific distance in a positive or negative direction.
By dragging the slider on the right of the window, you can uncover other parameters.
- Vel: It is the displacement value (in mm/s) of the X, Y platform when moving the X, Y platform using the machine manual control upper window.
- Move Abs XY: This part will be available if the tester is homed. It allows the user to move to a specific absolute position of the X, Y platform. This position is defined based on the home position.
The button on the left refreshes the current XY position.
You can enter the X and Y absolute position in the free space and then press ”XY Move” to move to this absolute position.
In the current version, the move Abs XY may have some problems, it is recommended to use the “Distance” of manual control explained previously.
- Teach Offset: This parameter is used to teach the offset between the testing and imaging position of the tester. This is the part where you can do the inline imaging calibration. It will be introduced further in Part 2.2.2.4.1.
- Move Offset: This parameter is used to automatically move between the testing and imaging position.
- TEST => IMG: The platform goes from the test position (where the sample is located below the load cell) to the imaging position (where the sample is located below the imaging head)
- IMG => TEST: The platform goes from the imaging position (where the sample is located below the imaging head) to the test position (where the sample is located below the load cell).
Make sure that you are using the right move offset type. If you are in the test position and use “IMG => TEST”, the platform will go in the wrong direction. It will be stopped and the initial position will be lost.
The “Move Offset” needs to be calibrated in order to efficiently move between the testing and imaging positions. The calibration will be introduced further in Part 2.2.2.4.1.
On the right side of the manual control window should be the manual module control. This window allows the user to manually use the module installed.
By clicking on the “ON” button, you can turn the motor off.
Next to it should be possible to modify an intrinsic parameter of the module: frequency (Hz), speed (RPM) etc…
The two buttons at the right start (Left one) and stop (Right one) the manual movement of the module.
The “Distance” button on the far right allows you to set a number of rotations / cycles.
