Maintenance: Check out Procedure
The test has failed if the measured values are greater than:
Patient Leakage Current, Mains on Applied Part
WARNING
PERSONAL SAFETY — MAINS VOLTAGE is applied to
floating input (patient connection) and patient cables/test
plug conductors and safety tester PATIN JACK. For the
protection of the person performing these tests, the
following values of resistor R may be used:

Type CF — 100 kOhm (220 to 240 V)
Disconnect safety tester from line voltage before connecting
patient cable/test plug to device.

After line voltage has been disconnected, connect the
patient cable/test plug to device.
This test performs leakage current tests during single fault conditions
(S.F.C.) with line voltage applied to the floating (patient connection)
inputs.
