QA-ES II Electrosurgical Analyzer
Introduction
The QA-ES II Electrosurgical Analyzer (hereafter called
the Analyzer) is a precision instrument for use in
performing tests on high-frequency electrosurgical units
(ESU) in accordance with national and international
standards. It is for use by trained service technicians.
Tests include:
• Automatic power distribution measurement
• Crest factor measurement
• RF leak measurement
• Return electrode monitor (REM) test
The Analyzer conducts testing by measuring the ESU
output against test loads set and adjusted in the Analyzer.
The Analyzer can automatically execute a power
distribution test with a load resistance ranging from 10
ohms to 5200 ohms. The Analyzer automatically
measures crest factor with a bandwidth of 2.5 MHz (with
loads), ensuring that the test result is reliable and
reproducible.
Test results shown in the Analyzer’s LCD display can be
printed out directly or transferred to a PC via the Ansur
QA-ES Plug-in test automation software. The Ansur
QA-ES Plug-in software allows you to design test
protocols, remotely control the Analyzer, and store test
results.
Carefully unpack all items from the box and check that
you have the items listed under Standard Accessories.
If you are missing any of these items, or if you find a
damaged item, follow the procedures found in the
Unpacking and Inspection Notices in the front of this
manual.

REM Alarm Test
The REM (Return Electrode Monitoring) alarm test
ensures that the ESU sounds an alarm if the resistance
between the two neutral electrodes exceeds its specified

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.

Electrosurgical AnalyzerFoot Switch Control
Foot Switch Control
There are three sets of two jacks each on the right side of
the Analyzer. The sets are as follows:
1. FOOT SWITCH (green jacks)
2. FIXED LOAD (white jacks)
3. VAR. LOAD, (red and black jacks)
Note
For the following instructions, refer to the ESU
manufacturer’s instructions to determine the
wiring of the ESU monopolar and bipolar foot
switch jacks. Only qualified technicians should
do this, since the technician will be responsible
for making appropriate and safe test cables.
Refer to Figure 5 and Table 5 for connection examples.

1. Connect the red jack on the Analyzer to the active
output on the ESU front panel.
2. Select a proper load for cut output on the ESU.
3. Connect the black jack on the Analyzer to the ESU
front panel via a dispersive return cable.
4. Connect one of the Analyzer green jacks to the cut
activate pin of the ESU foot switch.
5. Connect the other Analyzer green jack to the
common line of the ESU foot switch.
Coag Activation
1. Connect the Analyzer red jack to the active output on
the ESU front panel.
2. Select a proper load for the cut output on the ESU.
3. Connect the Analyzer black jack to the ESU front
panel via a dispersive return cable.
4. Connect one of the green jacks of the Analyzer to the
coag activate pin of the ESU foot switch
5. Connect the other green jack on the Analyzer to the
common line on the ESU foot switch.
Bipolar Testing
1.Connect the Analyzer red jack to the load for the
bipolar cut
2.Select a proper load for the
output
3. Connect the Analyzer black jack to the return of the
bipolar.
4. Leave the dispersive cable connected to the ESU so
that REM does not alarm. Disconnect this single-pin
banana plug from the Analyzer and place it on a nonconductive surface where it cannot contact anyone.
5. Connect one of the Analyzer green jacks to the
activate pin of the ESU bipolar foot switch. Connect
the other Analyzer green jack to the common line on
the ESU bipolar foot switch.
