Electrosurgery Analyzers
Key features
• Automatic power distribution
measurement, including power,
current, peak-to-peak voltage
(closed load only), and crest
factor
• Oscilloscope output
• High-frequency leakage mea-
surements with accuracy of
± 2 % of reading
• 128 internal user-selectable
test loads from 10 Ω to 5200 Ω
• Foot-switch output for trigger-
ing the ESU under test
• Ansur QA-ES software plug-in
for automated test protocols
• Large display
• RS-232 and Centronic-Printer
interface
QA-ES Series II analyzes electrosurgical units quickly and accurately. A
wide load-resistance range provides 128 user-selectable loads, including
very low loads for testing many of today’s ESUs.
An accuracy of ± 2 % of reading down to 20 mA guarantees reliable
high-frequency leakage results. With capability to run an automatic-power-
distribution test in as little as 1 minute, the QA-ES works fast so technicians
save time.
An Ansur QA-ES software plug-in allows users to create and automati-
cally run tests, capture data, and produce easy-to-read reports with a PC.
Modes of operation
Continuous operation Continuous measurement of power, current, peak-to-peak voltage
(closed load only), and crest factor
Single operation Single measurement after the set delay time of the ESU output of
power, current, peak-to-peak voltage (closed load only), and crest
factor
Power distribution Automatic measurement of power, current, peak-to-peak voltage
(closed load only), and crest factor through a user-selectable load
range
RF leakage current Provides connections and load configurations to measure HF
leakage from both grounded and isolated equipment
RECQM Test the “return electrode control quality monitoring
using the QA-ES internal loads
Manual/remote via Ansur test automation software

10 Ω to 2500 Ω in step of 25 Ω
2500 Ω to 5200 Ω in step of 100 Ω
Measurement True-rms value of applied waveform
RMS bandwidth 30 Hz to 10 MHz (-3 dB) for instrumentation only
30 Hz to 2.5 MHz (-3 dB) with loads
Low frequency filter 100 Hz filter to avoid low-frequency disturbance or interference
Current ± 5 % of reading for loads from 100 to 2000 ohms
Additional fixed load
200 Ω 400 W for 30 s; max 15 % duty cycle
Crest factor The higher of the two peak voltage measurements is used for
computation
Range: 1.4 to 16 (V peak/V rms).
Foot-switch output The foot switch output can be used to trigger the electrosurgical
unit
