ABB NTDO02 Digital power output

3. Program the module and data acquisition board to take data in the desired output mode, Multiplexed or Parallel. 4. Set the data acquisition board to a high gain and measure its offset by shorting its input. You must subtract this measured offset from all subsequent module measurements to ensure accuracy. 5. Measure the output of the first channel with its gain set to one and adjust its output offset pot until the output is close to zero. 6. Measure the output of the same channel with its gain set to 500 and adjust its input offset pot until the output is close to zero. 7. Repeat steps 5 and 6 until the offset at both gains is as close to zero as desired. 8. Repeat steps 5 through 7 for all other channels you want to calibrate. 9. Reinstall the module enclosure.
