Verifying REM Function
Equipment
•
REM plug and resistance substitution box
Procedure
1.
Set the resistance substitution box to 120 ohms. Connect the resistance box to
the generator and confirm that the REM Alarm 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 Alarm 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 Alarm indicator
illuminates green.
6.
Decrease the resistance to 10 ohms and verify that the REM Alarm 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
ohms 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 at these times:
•
after calibrating the generator
•
every six months
Equipment
•
Two small test cables (less than 24 inches long) with banana plugs
•
Current transformer
•
True RMS voltmeter (such as the Fluke 8920 or equivalent)
•
10, 100, 200, 300, 500, 750, 2000, 3000 ohm 1% noninductive power
resistors. (Series or parallel combinations of other values may be substituted if
these exact values are not available.)
•
Bipolar footswitch and monopolar footswitch
