10. Disconnect the Calibration Adapter from the amplifier.
Degauss
This is a functional test of the degauss operation. Refer to Figure 5--5.
1. Connect a current probe to the output of the amplifier. Do not clamp the
current probe around any conductor, but make sure the jaws are locked shut.
2. Press the amplifier PROBE DEGAUSS AUTOBALANCE button. When
the indicator turns green, the degauss operation has successfully completed.
3.
Verify that there are no error codes. Error codes display on the Probe Status
LEDs when the AC and DC COUPLING LEDs alternately flash.
4. Record the results (pass/fail) on the test record.
