Analog Calibration (±1 calibration bit = ±0.005mA adjustment)
Analog output calibration sends a positive or negative o set to the respective output channel's digital to
analog converter (DAC.) The DAC has a resolution of 0.005mA/bit.
For example: to shift the analog output up by 0.1mA, set the analog o est value to +20. ( 0.1 / 0.005 = 20)
