Warning
When GROUND MODE is set to OFF, the DUT,
fixtures or connected instrumentation cannot be
grounded. This will short circuit the internal
circuitry during a test.
For ACW and DCW tests, if it is not known whether
the DUT test setup is grounded or not, always set
GROUND MODE to ON.
Only set GROUND MODE to OFF when the DUT
is floating electrically.
Steps 1. Press the UTILITY key on the front
panel when the tester is in EDIT
status. The display will go from the
normal EDIT status to the MANU
Utility menu for the current test.
