Fluke QA-ES II Electrosurgical Analyzer Repair
The Fluke QA-ES II is an electrosurgical analyzer – it measures the high-frequency power an electrosurgical generator delivers into a known load, which is a demanding measurement because of the frequencies and power levels involved.
Is your Fluke QA-ES II worth repairing?
High replacement cost and few alternatives. The internal load bank and the RF measurement path are what fail, and both are serviceable. Our answer for the Fluke QA-ES II: Repair and recalibrate. Generator verification depends on the load and the measurement both being right. We evaluate free of charge and quote before any work begins, and if the numbers do not favour repair we say so rather than quoting anyway.
What typically fails on the Fluke QA-ES II
- Crest factor or waveform analysis faults.
- Connection or footswitch interface faults.
- Display, memory or export faults.
- Power measurement drifted – the primary function, and one that silently passes generators it should fail.
- Internal load bank faults – load resistance shifting, which changes every power reading.
- RF leakage measurement errors.
What you get back
Component-level repair rather than assembly swapping, NIST-traceable calibration with the measured results documented, and a 90-day parts-and-labor warranty. Most instruments are back with you inside 5-10 business days.
Fluke Service Center works on Fluke instruments only. Send it in for a free evaluation, or email us with the model and the symptom and we will tell you what to expect before you ship anything.
