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).
