Hi, I am working with a weighing scale. I have used cs5460a adc and 89c52
controller.
while i am trying to do offset calibration(dc, current channel),
i am getting a large value in the offset register and wrong values in the
instantaneous current register.

The new offset register value which i am getting is in the range of
7E4xxx.

I set the PGA as x50 so that the differential input range is ±50mV.

Plz someone help me to do the offset calibration
