ESU Analyze FAQs
Q1: What is the main purpose of this high frequency electrosurgical analyzer?
A: It measures key performance and safety parameters of electrosurgical units (ESUs), including output power in various modes, high-frequency leakage current, REM/CQM function, power distribution curves, crest factor, and more โ ensuring compliance with safety standards and reliable clinical performance.
Q2: Which standards does this analyzer comply with?
A: It fully supports IEC 60601-2-2:2017 (including AMD1:2023), WS/T 602-2018, JJF 1217-2025, and GB 9706.202-2021 (modified adoption of IEC). This makes it suitable for global export, Chinese regulatory requirements, preventive maintenance, and calibration verification.
Q3: How accurate is the power and leakage current measurement?
A: Power accuracy is typically ยฑ2.5% or better (reading), and leakage current accuracy is typically ยฑ5% or better โ competitive with leading analyzers for high-power and high-frequency ESU testing.
Q4: Can it test REM / CQM (Return Electrode Monitor / Contact Quality Monitor) functions?
A: Yes โ it provides full verification, including adjustable impedance simulation (typically 5 ฮฉ โ 150 ฮฉ), alarm threshold testing, activation timing, and reliability checks in both manual and automatic modes.
Q5: Does it support testing of modern ESU modes like vessel sealing or advanced waveforms?
A: Yes, it handles pure cut, blend cut, coagulation, fulguration, desiccation, spray, vessel sealing, electric stimulation modes, and non-standard RF waveforms with deep waveform buffering for stable capture.
Q6: How often should ESUs be tested using this analyzer?
A: Follow manufacturer recommendations, hospital policy, or regulatory guidelines โ typically annually for preventive maintenance, after repairs, during acceptance testing, or as required by JJF calibration cycles.

A: It offers comparable measurement depth, waveform fidelity, true RMS accuracy, and REM/CQM testing capabilities at a more practical price point, while fully meeting the same key international and Chinese standards.
Q11: Why is an ESU Analyzer essential for medical device testing?
An ESU Analyzer ensures that Electrosurgical Units (ESU) are performing within safe limits. It measures high-frequency parameters like power output, leakage current, and crest factor. Testing with a professional analyzer like the Kingpo ESU Tester is critical to prevent patient burns and ensure compliance with IEC 60601-2-2 standards.
Q12: Does the Kingpo ESU Analyzer come with a calibration certificate?
Yes. Every Kingpo ESU Analyzer includes a traceable Calibration Certificate PDF. This document verifies the instrument's accuracy against national standards, which is a mandatory requirement for hospital audits and ISO quality management systems.
Q13: Which electrosurgical units (ESU) is this tester compatible with?
Our ESU Analyzer is universally compatible with major brands, including ValleyLab (Covidien), Bovie, ConMed, and Erbe. It supports testing for both monopolar and bipolar outputs, providing accurate RMS measurements for various waveforms.
Q14: How often should an Electrosurgical Unit be tested?
According to most hospital PPM (Planned Preventive Maintenance) protocols and international standards, ESUs should be tested at least once a year. However, after any major repair, a full safety and performance validation using an ESU analyzer is required before returning the unit to the operating room.
Q15: Can this analyzer measure high-frequency leakage current?
Absolutely. The Kingpo ESU Analyzer is specifically designed to measure HF leakage current in multiple configurations (active to ground, dispersive to ground, etc.), ensuring the electrosurgical generator's isolation meets safety thresholds.
