WARNING - USERS
The ESU-2300 Analyzers are for use by
skilled technical personnel only.
WARNING - USE
The ESU-2300 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-2300 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 - TEST LEADS
There are retractable ends on the test leads for
use with the ESU to avoid possible electric
shock, skin burns or personal injury.
Do not touch any metal on the
banana plugs or probes.
2
WARNING - POWER SUPPLY
Unplug the Power Supply 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.
3
CAUTION - SERVICE
The ESU-2300 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-2300 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 - VENTILATION
The ESU-2300 Analyzers include ventilation grills
on either side of the units to help prevent
overheating during operation. These grills and
internal fan should not be blocked.
Continuing to apply a high-level ESU signal
after an Error Message,
can result in damage to the unit.
CAUTION - CLEANING
Do not immerse. The Analyzer should be
cleaned by wiping gently with a damp, lint-free
cloth.
CAUTION - INSPECTION
The ESU-2300 Analyzers should be
inspected before each use for wear and
the Analyzer should be serviced
if any parts are in question.

ESU-2300
ELECTROSURGICAL UNIT ANALYZER
The Model ESU-2300 is a high-accuracy Electrosurgical Analyzer. The “measurement
engine” of the ESU-2300 is a specially-engineered True-RMS RF Ammeter and Wattmeter,
particularly suited to measuring the complex RF waveforms produced by electrosurgical
generators. The ESU-2300 has been designed to comply with electrosurgical manufacturer
industry standard current sensing technology, and thus utilizes an internal precision RF
Current Transformer. The analyzer utilizes a precision internal test load resistor network.
The ESU-2300 is intended to be routinely used to measure the various parameters relating
to the testing and performance validation of electrosurgical generators. The Patent Pending
®
DFA
Technology allows the ESU-2300 to aggressively digitize the complex electrosurgical
generator waveform, analyze its components and provide highly accurate and stable
results. It may be used as a stand-alone meter or in conjunction with a PC utilizing the
optional software.

GENERAL OPERATION
The ESU-2300 is controlled by 5 light touch keys for navigation, plus 1 light touch key for
LCD display backlight control. The navigation keys allow the user to move around within
the displayed parameters, select the desired options, choose a specific category and
control the setup for the unit. When a key is depressed there is an audio click when it is
accepted, or a “Razz” tone if the key is invalid.
A large LCD graphics display with high intensity white backlight provides the user with
information about the current status of the device configuration options, test results and
more. The display identifies the function of each key on a dynamic basis. As the operation
mode changes, the key functions change to suit the operating mode.
BACKLIGHT KEY
The Graphic LCD display may be viewed with or without the backlight. Depressing any key
will activate the backlight. However, since the backlight will drain the internal rechargeable
battery at an accelerated rate if left on, it will automatically be shut off after a user
programmable delay when running the ESU-2300 on battery power.
The key is provided to toggle the backlight on or off at any time.
NOTE: The backlight parameter in the System Setup screen may be set to Off, 1-20 sec or
Always On.
13
FUNCTION KEYS
There are five keys that are used to provide general operational control. The
functions of the keys vary depending on the current screen. The section of the screen
just above the key indicates its current meaning.
NOTE: Only functions that are available to the user will be visible at any given time.
Sample Function Key Labeling
SERIAL COMMUNICATION
There are two serial ports on the side panel. One is a standard USB port and the other is a
DB9 RS232 port. The RS-232 Port is used for field Firmware upgrades via the FLASH
Update PC Utility and the USB Port is used to interface with a PC for remote control
operation or digitized electrosurgical waveform capture.
OSCILLOSCOPE OUTPUT
A BNC connector is provided to connect an oscilloscope to the unit. This output is an
uncalibrated attenuated version of the ESU Generator output waveform.
POWER SWITCH
The main power switch for the Analyzer is located on the side panel.
14
LINE POWER
A Kycon 3 position locking connector is provided for the 9 VDC external universal power
supply for using the ESU-2300 with line power. When connected to line power, this
connection provides a connection for Earth/Ground.
NOTE: While operating the ESU-2300 on battery power, a Jumper Lead must be run
from the Earth/Ground Jack to an Earth/Ground point for all of the RF leakage tests.
(See Leakage Tests for more information.)
The Universal Power Supply takes a Standard Power Adapter Cable with Small
Standard Product Plug and Required International Connector (See Options Below).
