Setting a Reference Value
Background
The REF# acts as an offset. The REF# value is
subtracted from the measured current (ACW,
DCW) or measured resistance (IR, GB).
Steps
1. Press the UP / DOWN arrow keys
to bring the cursor to the
REF# setting.

Note
For GB tests, a reference offset can be
automatically created using the zeroing function.
