This manual covers the model ESU-2400 and ESU-2400H Electrosurgical Unit Analyzers.
Throughout this manual the term ESU-2400 will be used to apply to both models. Sections
that are specific to the ESU-2400H model will use the term ESU-2400H exclusively.
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
DFA2Technology®(Patent Pending) utilized in the ESU-2400H allow the system to
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.

CQM Cable Differences –Two CQM cables are provided in the standard accessory kit.
The only difference between them is that one cable has a small pin and the other does
not. The cable with the pin is used to enable the REM circuitry on the DUT. The cable
without the pin is used to bypass the REM circuit and allow for shorting of the REM leads.
Note that some generators do not allow for the REM circuit to be disabled. For these
generators it does not matter which cable is used.
When using the ESU-2400 CQM test mode, the cable with the pin must be used.
For other modes, the Dispersive ports on the ESU-2400 are shorted together and the
cable without the pin should be used.

OVERVIEW

The ESU-2400 Series utilizes an internal current transformer and internal precision load
resistors for simple configuration of typical Electrosurgical Generator testing. Many of the
world’s leading Electrosurgical generator manufacturers utilize this exact same technique
when they test, service and calibrate their generators.
Internal configuration relays allow for simple connections to the DUT. When the Measure
RF Energy, Measure RF Leakage, or REM/ARM/CQM mode is selected from the main
menu, the relays configure the internal connections as required. Shown below are
examples of external connections to the DUT.
Monopolar:
1. Yellow Active Lead from Active Jack on ESU-2400 to DUT Output.
2. Blue Dispersive Lead from Dispersive Jack on ESU-2400 to DUT Dispersive.
