11. Set the power switch of the device under test to OFF.
Patient (Source) Leakage Current
This procedure only applies to Class I (grounded/earthed) equipment,
and measures the leakage current from the ECG/RESP connector of the
device to ground.
1. Configure the leakage tester like the circuit shown below with GND
switch OPEN and polarity switch NORM.
2. Connect an ECG test body to the ECG/RESP connector of the device
under test.
3. Set the power switch of the device to ON.
4. Read the leakage current indicated on the DMM.
5. Change the leakage tester polarity switch to the RVS position.
6. Read the leakage current indicated on the DMM.
NOTE
If either reading is greater than 50 µA (0.05 volts on the DMM), the
device fails this test. Contact GE 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 Technical Support.
11. Set the power switch of the device to OFF.
NOTE
The AAMI and EN single fault condition (ground open) is 50 µA,
