User calibration

The intended purpose of the user calibration is to calibrate the device, for example, in a smaller output signal range than that calibrated by the vendor. As a result, a higher accuracy can be attained for the smaller output signal range.

The correction function has the same form as the correction function of the vendor calibration:

 

YU = GU * XU + OU

YU: Output value after user calibration

XU: Output value before user calibration

GU : Gain

OU : Offset

Enabling the user calibration

The user calibration is disabled in the factory. It can be enabled individually for each output. To do this, set the corresponding CoE parameter "Enable user calibration" to TRUE:

Setting the calibration coefficients

Set the calibration coefficients via the CoE parameters "User calibration offset" and "User calibration gain":
