CC-65 accuracy

Customer Consultation:

We have bought a CC65 current clamp, this unit have a 4% error at 50A, we have try to calibrate with or calibration shunt of 0.1% error adjusting the VR2 potentiometer, we can calibrate the output at 50A but it seems not linear and then it have error at 20-25A

This clamp has a lot of potentiometers inside, but Do you have a calibration manual for this clamp?
