G6100 Plus Leakage Current Tests
The Guardian 6100 Plus Medical Safety Analyzer measures Earth Line Leakage,
Enclosure Leakage, Patient Line Leakage and Patient Auxiliary Leakage Current. The
instrument simulates the human body models listed in Table 2-8. The test modes and
other programming parameters are also listed in Table 2-8. The Earth LC Test is the sum
of all leakages of current in the DUT (device under test). The test measures the current
flowing back to Earth Ground through the ground conductor of the line (power) cord.
