Verifying REM Function
Equipment required:
REM plug and resistance substitution box.
1. Set the resistance substitution box to 120 ohms. 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 ohms.
3. Decrease the resistance to 60 ohms and verify that the REM indicator
illuminates green.
4. Increase the resistance to 100 ohms and verify that the REM alarm
sounds.
5. Decrease the resistance to 30 ohms and verify that the REM indicator
illuminates green.
6. Decrease the resistance to 10 ohms and verify that the REM indicator
illuminates green.
7. Decrease the resistance to 3 ohms and verify that the REM alarm
sounds.
8. Switch to a connector without the pin, and increase the resistance from
3 to 24 ohms. 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 61 cm [24 in.] long) with banana plugs
• Current transformer
• True RMS voltmeter (such as the Fluke 8920 or equivalent)
• 100, 300, and 500 ohm 1% noninductive power resistors
• Bipolar footswitch and monopolar footswitch.
