Introduction to Dynamic Compensation Technology
Dongguan / Nanning, China — KINGPO Technology Development Limited has announced a breakthrough in high-frequency electrosurgical unit (ESU) testing technology with the launch of its KP8850 Series ESU Analyzer. In collaboration with Guangxi Food and Drug Evaluation and Inspection Center and Guangxi Medical Device Testing Center, KINGPO participated in the development of a dynamic compensation method aimed at improving the accuracy of high-frequency ESU testing. This advancement comes with the ability to meet the latest compliance standards, such as GB9706.202-2021 and IEC 60601-2-2.

Technical Milestone: Dynamic Compensation Reduces Measurement Error
Electrosurgical units (ESUs) and RF ablation devices operate at frequencies above 1 MHz. This presents unique challenges for traditional testing systems, which may suffer from parasitic capacitance and inductance that distort impedance measurements. The research team behind the KP8850 Series has developed a real-time dynamic compensation method, significantly reducing impedance errors.
The method, based on high-frequency LCR meters and vector network analyzers, was tested across a frequency range of 1-5 MHz, showing a reduction in impedance measurement error from 14.82% to just 1.81%. Additionally, phase error decreased from 9.8° to 0.8°, thus providing engineers with a more reliable and repeatable testing solution.
