Introduction
The RF303 Electrosurgical Analyzer, hereafter referred to as the “Analyzer”,
tests electrosurgical units (ESU) for generator output and high frequency (HF)
leakage. It is compatible with both isolated and earth/ground-referenced types
of electrosurgical units. You can test both the high-level monopolar and the
low-level bipolar ESU outputs using this versatile Analyzer.
The Analyzer uses a precision high-voltage capacitive attenuator to sample the
applied ESU signal. You can use this attenuated HF voltage and the selected
test load resistance value to derive the true-rms values of both current and
wattage.
The Analyzer internal test load simulates the range of resistance encountered
during surgical procedures. Additionally, a second, 200 ohm (e) auxiliary test
load resistance is built-in to analyze earth/ground-referenced ESUs as specified
in the International Standard IEC 601-2-2.
The exclusive use of non-conductive, high-impact plastic case material
minimizes extraneous high frequency leakages within the Analyzer.
General Safety Information
This Analyzer complies with safety and technical requirements described in
the following directives:
•UL 3101-1
•CAN/CSA C22.2 No. 1010.1 (1992)
•EC 73/23/EEC EN 61010–1
•ANSI / AAMI HF–18-1986
•IEC 601-2–2
•IEC 1289-1
•IEC 1289-2
A Warning identifies hazardous conditions and actions that could cause
bodily harm or death.
A Caution identifies conditions and actions that could damage the Analyzer,
the equipment under test, or cause permanent loss of data.

Warnings and Cautions
When testing electrosurgical units, observe the following to ensure operator
safety and maintain integrity of the high frequency (HF) measurement.
WXWarning
To avoid possible electric shock, burning of the skin, or
personal injury, follow these guidelines:
•Use only test leads supplied with the Analyzer to test the
ESU. These test leads utilize a shrouded 4mm plug to
limit exposure to the high-voltage and high frequency
ESU signal. The retractable ends of these leads are for
use on ESU only.

Introduction and Specifications
General Safety Information 1
1-5
•Do not plug in or remove a test lead from either the ESU
or the Analyzer while the ESU generator is activated (or
keyed). This high frequency ESU signal can be several
thousand volts in amplitude when the output is open-
circuited.
•Whenever practical during testing, activate the ESU
generator output using the foot switch supplied with the
ESU.
•No probes or accessories supplied with the analyzer are
intended for handheld use. Set up using the safety test
leads and stand clear when activating the ESU with the
footswitch.
•Place the Analyzer on an insulated, non-conductive work
surface to limit possible HF current paths to earth
ground.
•Routinely inspect test leads for wear and tear. Repair or
replace the test leads to maintain operator safety and
Analyzer performance.
Note
To ensure accuracy of measurement, follow these guidelines:
•Whenever practical during testing, place test leads carrying the
ESU signals in parallel, approximately 0.5 meters apart, to limit
capacitive coupling.
•Avoid crossing or tangling test lead cables during use and do not
drape them across conductive, grounded surfaces. Due to their
length, erroneously high HF readings may result.
