SET UP AND OPERATION INSTRUCTIONS
GUARD MODE CONFIGURATION
In this configuration the Guard and Ground is connected together with an external jumper or a
switch internal to the Test Set, depending on the design. Any current associated with the Return
is indicated on the current meter. Any current associated with the Guard bypasses the current
meter. Leakage current through the test specimen is indicated on the current meter. Stray
leakage to earth ground is not indicated on the current meter. This configuration can not be used
if it is not possible to isolate the return side of the Test Specimen from earth ground.
