Range Zero, LF, and HF Gain Calibration Procedure (not in Spot Frequency mode)
Using the following procedure to calibrate range zero then range LF and HF gains on all
ACV ranges at the voltages and frequencies detailed in Table 3-4. Just one range can be
calibrated if required, but for a full-calibration start with the 200 mV range and work up
to the 1kV range.
