4.1.2.2.1 Voltage and Current Offset Calibration

To calibrate the voltage and current offset, perform the following steps:

  1. Connect the GUI to view results for voltage and current.
  2. Configure the test source to supply the desired voltage and current.
    • Using a low but non-zero value is recommended; for example, 120V and 1A.
  3. Click on the Manual cal. button.
  4. Input the difference from the expected input versus what the GUI is reading into the appropriate fields.
    Note: AC current offset is in microamps and AC voltage offset is in millivolts.
