Hi,
How can it be that you calibrated it and it shows wrong values?
How did you do the calibration?
If you need more help you should provide all necessary infirmation.
* your circuit schematic (not the darasheet's schematic)
* your PCB layout
* the IC setup
* your analog input signals (voltage/current, frequency, waveform, how reliable are they)
* the output signal.
--> only with the complete signal flow (from generated analog signals .... to digital output signals) we are able find out the problem.
