Vendor calibration
Each analog input is calibrated in the factory. The results of the calibration are the coefficients of a correction function. The correction function is:
| YV = GV * ( XV - OV ) | YV : Measured value after the vendor calibration XV : Measured value before the vendor calibration GV : Gain of the vendor calibration OV : Offset of the vendor calibration |
The coefficients GV and OV cannot be changed by the user. If you wish to carry out a calibration yourself, use the User calibration.
Disabling the vendor calibration
Note | |
Measuring error with disabled vendor calibration The measuring error specified in the technical data is no longer guaranteed if you disable the vendor calibration. |
If you use the user calibration, it may be a good idea to disable the vendor calibration.
Set the "Enable vendor calibration" parameter to FALSE to disable the vendor calibration for the respective input.
