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.

Safety
WCaution
To avoid damage to the Analyzer:
• Calibrate the Analyzer annually.
• Only qualified technical personnel should
perform troubleshooting and service
procedures on the Analyzer.
• Do not use the Analyzer for anything other
than measuring RF outputs from
electrosurgical units.
• Ensure there is at least six inches of air
space above and behind the Analyzer to
allow air circulation to cool internal load
resistors.

during the power distribution test, the ESU output power
automatically powers on and off. The ESU activates, the
Analyzer gets the reading on the first selected load, and
then the ESU turns off while the Analyzer changes the
load to the second selection. Next, the ESU powers on
again and the Analyzer gets the reading. This cycle

steps through the loads with a delay between each,
as set in the test SETUP screen. The Analyzer
displays values on the screen for each load as it
steps through the test.
(If connected to a printer, the Analyzer writes a line of test
results for each step in the Power Distribution Test.)
HF Current Leakage Test
This test checks whether the active and dispersive
leakage currents are within acceptable limits. There are
four test setups to accomplish this testing.
The ESU must operate at the maximum output setting in
each operating mode per IEC 601-2-2 and ANSI/AAMI
HF18-2001 specifications. The limits for the acceptable
leakage currents depend upon the test configuration as
shown in Table 4.

Test Procedure
To run an HF Leakage Test, perform the following steps:
1. Connect the Analyzer to the ESU to test leakage
from the Active electrode using the appropriate
setup, as shown under “HF Isolated Equipment” or
“Ground HF Equipment.”
2. Press F2 until an asterisk (*) symbol appears
following ‘Mode’.
3. Rotate the encoder knob until the *RF Leakage test
mode appears on the screen, and then press the
Enter key.
4. Set the ESU as prescribed by the manufacturer for
leakage tests and then activate the ESU.
5. With the ESU activated, press START (F3); the
Analyzer takes the leakage measurement.
6. Repeat the leakage test as needed for other ESU
accessories.
If connected to a printer, the Analyzer writes a line of test
results to the printer following each HF Leakage Test.
Measuring Leakage Current with HF Isolated Equipment
Make measurements of the HF current leakage from the
active and neutral electrodes. The test load is 200 ohms,
and the ESU must be operating at maximum power.
