Patient (Sink) Leakage Current Test; (Mains Voltage On The Applied Part) - GE Solar 7000 Service Manual

Patient (Sink)
Leakage Current Test
(Mains Voltage on the
Applied Part)
3-14
MAINTENANCE: Electrical Safety Tests
NOTE
If either reading is greater than 50 µA (0.05 volts on the
DMM), the device fails this test. Contact GE Medical
Systems Information Technologies Technical Support.
7. Change the GND switch to the Closed position.
8. Read the leakage current indicated on the DMM.
9. Change the leakage current switch to the RVS position.
10. Read the leakage current indicated on the DMM.
NOTE
If either reading is greater than 10 µA (0.01 volts on the
DMM), the device fails this test. Contact GE Medical
Systems Information Technologies Technical Support.
11. Set the power switch of the device to OFF.
NOTE
The AAMI and IEC single fault condition (ground open)
is 50 µA, whereas the normal condition (ground closed) is
less.
This procedure only applies to Class I (grounded/earthed) equipment,
and measures the leakage current from a mains voltage source into the
ECG/RESP connector.
1. Configure the leakage tester like the circuit shown below with GND
switch CLOSED and polarity switch NORM.
