9. Set the polarity switch to RVS.
10. Read the current leakage indicated on DMM.
NOTE
If the reading is greater than the specification below, and the
device under test is powered from 100-240 V/50-60 Hz, the device
under test fails. Contact GE Technical Support.
100 microamperes (0.1 volts on the DMM), and the device under
test is powered from 100-240 V/50-60 Hz.
11. Set the power switch of the device under test to OFF.
This test pertains to the Solar 8000M/i, part of the monitoring system.
This procedure only applies to Class I (grounded/earthed) equipment,
and measures the leakage current from the ECG/RESP connector then the
SpO2 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.
