| Six simple measurements are necessary to get the correction factors for the span compensation resistor and the offset correction.
The correction factors are calculated as
These values are to be written into registers TKOffs and TKGain of the PS021. By means of this simple method a scale can be built that fulfills the quality requirements of calibrated scales.
Example for a Software Compensation
Start with taking a loadcell that wasn't temperature compensated yet.
The correction parameters then are:
- TKOffs = 61.7
- TKGain = 0.9817
