Setting the scaling

Die EingThe input windows for the scaling are called up via the button "Scaling" in the main window "Configuration".

The scaling factor can be determined:

  • by entering the sensor data "characteristic value", "nominal force" and the input sensitivity of the measuring amplifier
  • by performing a 2-point calibration, measuring the signal without load and with a known load (calibration weight)
  • for measurements with strain gauges by entering the bridge type, the k-factor and, if necessary, the cross-contraction number, as well as the input sensitivity of the measuring amplifier

 

 

 

 

Enter the sensor data

A scaling factor of 107.093 [N/2 mV/V] is obtained for the amplifier with an input sensitivity of 2 mV/V for a sensor with a nominal force of 100 N and a characteristic value of 1.86754 mV/V (characteristic value = output signal for nominal force at 1V bridge supply voltage).

Only the resulting scaling factor is stored in the measuring amplifier.

The software carries out the calibration procedure with a defined calibration load:

Enter the calibration load (the unit of the calibration load is selected in the main window)

Measurement in unloaded condition

Measurement with applied calibration load

At the end of the calibration process, press "OK / Set". Only the resulting scaling factor is stored in the measuring amplifier.

 

By entering the bridge type, the k-factor and, if necessary, the cross-contraction number, the scaling factor for the display of the strain is calculated in μm/m.

At the end of the calibration process, press "OK / Set". Only the resulting scaling factor is stored in the measuring amplifier.
