MAINTENANCE: Electrical Safety Tests
7. Set the GND switch on the leakage tester to CLOSED.
8. Read the current leakage indicated on DMM.
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 Medical
Systems Information Technologies 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 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.
