Return Connection
When the instrument Return is grounded, any internal and external stray leakage will be
monitored due to currents that flow from High Voltage to earth ground (such as from HV to the
chassis of the instrument). This current is inherent and will cause errors when trying to monitor
very low leakage currents in the microampere range.
It is important to note that grounding the return lead will disable the Smart GFI function. Smart
GFI allows the user to automatically configure the instruments return configuration. When the
Return lead is earth grounded, the GFI circuit is disabled and the instrument operates in a
grounded return mode of operation.
Please refer to section
4.1.2 System Parameters
for a complete explanation of the GFI
function.
