Verifying REM Function
Equipment required
REM plug and resistance substitution box.
1. Set the resistance substitution box to 120 Ω. Connect the resistance box to the
generator and confirm that the REM indicator illuminates green.
2. Slowly increase the resistance and verify that the REM alarm sounds at 135 ± 5 Ω.
3. Decrease the resistance to 60 Ω and verify that the REM indicator illuminates green.
4. Increase the resistance to 100 Ω and verify that the REM alarm sounds.
5. Decrease the resistance to 30 Ω and verify that the REM indicator illuminates green.
6. Decrease the resistance to 10 Ω and verify that the REM indicator illuminates green.
7. Decrease the resistance to 3 Ω and verify that the REM alarm sounds.
8. Switch to a connector without the pin, and increase the resistance from 3 Ω to 24 Ω.
Verify that the REM alarm sounds.
Confirming Outputs
Use this procedure to ensure the accuracy of the generator. Always confirm the output:
• After calibrating the generator
• Every six months
Equipment required
• Two small test cables (less than 24" [61 cm] long) with banana plugs
• Current transformer
• True RMS voltmeter (such as the Fluke 8920 or equivalent)
• 100, 300, and 500 Ω 1% noninductive power resistors
• Bipolar footswitch and monopolar footswitch
Checking the Bipolar Output
1. Verify that the generator successfully completes the self-test as described in
Generator Self-test on page 5-18 in this section.
2. Connect the test equipment for bipolar output.
a. Connect the two test cables to the Bipolar Instrument receptacle.
b. Pass one test cable through the current transformer and connect the current
transformer to the voltmeter.
