limit. The program directs the QA-ES to increase the
resistance gradually, starting at 10 ohms and increasing
through all available load settings. At a certain value, the
ESU should sound an alarm. See Figure 10 for the test
setup for the ESU REM Alarm Test using the Analyzer
foot switch trigger. You can use the same red and black
connections with the ESU triggered by its foot switch or
hand switch.

Figure 10. REM Alarm Test Setup
To run a REM test, perform the following steps:
1. Connect the Analyzer to the ESU as shown in
Figure 10.
2. Press F2 until an asterisk (*) symbol appears
following ‘Mode’.
3. Rotate the encoder knob until the REM Test test
mode appears on the screen, and then press the
Enter key. This mode generally tests any of the
monitoring and alarm systems for return, neutral, or
dispersive electrodes.
4. Set the Delay time for the test. Fluke Biomedical
recommends a significant delay time (2000 to
4000 ms) to identify the alarm point more easily.
5. Press START (F3) to begin the REM test.
6. When the ESU alarm sounds, press STOP (F3) to
end the test. The load at which the alarm activated
stays on the screen.
If connected to a printer, the Analyzer writes a line of test
results to the printer following the REM test.
