Description

The Model ESU-2400 Electrosurgical Unit Analyzer is a high-accuracy True RMS RF

Measurement system designed to be used in the calibration and routine performance

verification of Electrosurgical Generators. It offers a higher degree of accuracy than

previously attainable with conventional Electrosurgical Unit Analyzer designs. The ESU-

2400 provides an advanced low reactance internal load bank with a range of 0 to 6400

ohms in 1 ohm increments. It is microprocessor based and utilizes a combination of

unique hardware and software to provide accurate and reliable test results, even from

difficult waveforms such as “Spray”. The DFA Technology  utilized in the ESU-2400 and

Technology  (Patent Pending) utilized in the ESU-2400H allow the system to 2 DFA

aggressively digitize the complex RF waveforms produced by Electrosurgical Generators, analyze each individual digital data point, and provide highly accurate measurement results. 

The ESU-2400, unlike many conventional ESU Analyzers, has internal high voltage setup relays to control the measurement path, allowing the user to switch between Power measurements, Leakage measurements, REM/ARM/CQM testing, or even run an autosequence that could include any or all of these tests – without even moving wires around!

The current transformer internal to the ESU-2400 senses the RF current flowing through the internal test load and produces a ratiometric voltage which is digitized and analyzed by the microprocessor. Combining the standard and low ranges of the ESU-2400 with the use of the current transformer, the user has full control over the ability to get high accuracy and high resolution readings from all types of Electrosurgical Generators.
