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 automatically run tests, capture data, and produce easy-to-read reports with a PC.

Technical Specifications

Generator Output

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
