Setting the Grounding Mode
Background
When GROUND MODE is set to ON, the IIT-2000/
2010/5000/5010 grounds the return terminal to the ground.
This mode is best for DUTs that are grounded to an earth
ground by their chassis, fixtures or operation environment.
This mode measures the potential of the HIGH VOLTAGE
terminal with respect to earth ground. This means that any
stray capacitance/resistance that leaks to earth ground will
also be measured. This is the safest testing mode, though
potentially not as accurate.
When GROUND MODE is set to OFF, the return terminal is
floating with respect to the earth ground. This mode is for
DUTs that are floating and not directly connected to an earth
ground. This is more accurate than when GROUND MODE is
set to ON as any stray capacitance/resistance that leaks to the
earth ground from the DUT side of the testing circuit will not be
measured. For this reason, this testing mode is able to
