WARNING - USERS
The ESU-2050 Analyzers are for use by
skilled technical personnel only.
WARNING - USE
The ESU-2050 Analyzers are intended for testing
only and they should never be used in
diagnostics, treatment or any other capacity
where they would come in contact with a patient.
WARNING - MODIFICATIONS
The ESU-2050 Analyzers are intended for use
within the published specifications. Any
application beyond these specifications or any
unauthorized user modifications may result in
hazards or improper operation.
WARNING - CONNECTIONS
All connections to patients must be removed
before connecting the Device Under Test (DUT)
to the Analyzer. A serious hazard may occur
if the patient is connected when
testing with the Analyzer.
Do not connect any leads from the patient
directly to the Analyzer or DUT.
WARNING – POWER ADAPTOR
Unplug the Power Adaptor before
cleaning the surface of the Analyzer.
WARNING - LIQUIDS
Do not submerge or spill liquids on the Analyzer.
Do not operate the Analyzer if internal
components not intended for use with fluids may
have been exposed to fluid, as the internal
leakage may have caused corrosion and be a
potential hazard.
2
CAUTION - SERVICE
The ESU-2050 Analyzers are intended to be
serviced only by authorized service personnel.
Troubleshooting and service procedures
should only be performed by
qualified technical personnel.
CAUTION - ENVIRONMENT
The ESU-2050 Analyzers are intended to function
between 15 and 30 °C.
Exposure to temperatures outside this range can
adversely affect the performance of the Analyzer.
CAUTION - CLEANING
Do not immerse. The Analyzer should be
cleaned by wiping gently with a damp, lint-free
cloth.
CAUTION - INSPECTION
The ESU-2050 Analyzers should be
inspected before each use for wear and
the Analyzer should be serviced
if any parts are in question.

ELECTROSURGICAL UNIT ANALYZER
The Model ESU-2050 Electrosurgical Unit Analyzer is a high accuracy True RMS RF
Voltmeter designed to be used in conjunction with an RF Current Transformer to measure
various parameters relating to Electrosurgical Units. It is microprocessor based and utilizes
a combination of unique hardware and software to provide meaningful and accurate results
even from difficult signals (like Spray). The Patent Pending DFA
system to digitize the signal, analyze its components and provide highly accurate results. It
may be used as a stand-alone meter or in conjunction with a PC utilizing the provided
software.
The following are highlights of some of the main features:
®
• TRUE RMS READINGS USING DFA
TECHNOLOGY
• MV, MV PEAK, MA, CREST FACTOR AND WATTAGE RANGES
• LARGE GRAPHICS DISPLAY WITH CURSOR SELECTION

MAIN SCREENS
– There are six main screens, 5 Display Screens which have 1, 2, 3, 4
and 5 display zones respectively and the Quick Config screen which displays the current
hardware configuration. In the Display Screens, each Display Zone can be customized to
show the desired parameter of mV RMS, mA RMS, Watts, mV Peak or Crest Factor.
The available screens can be toggled through using .

The Quick Config Screen allows the user to see the current configuration and provide a
quick method of changing the RF Current Transformer (Donut) Attenuation or Load
Resistance parameters.
Use to highlight the parameter to change and then to sequence through
the available options.
NOTE: On power up, the Quick Config Screen will display for a few seconds to indicate the
current configuration and then the default Display Screen will be displayed. The Quick
Config Screen can be accessed using .
