Warranty and Product Support

Fluke Biomedical warrants this instrument against defects in materials and work­manship for one full year from the date of original purchase. During the warranty
period, we will repair or, at our option, replace at no charge a product that proves
to be defective, provided you return the product, shipping prepaid, to Fluke Bio­medical. This warranty does not apply if the product has been damaged by acci­dent or misuse or as the result of service or modification by other than Fluke Bio­medical. IN NO EVENT SHALL FLUKE BIOMEDICAL BE LIABLE FOR
CONSEQUENTIAL DAMAGES.

Only serialized products and their accessory items (those products and items bear­ing a distinct serial number tag) are covered under this one-year warranty.
PHYSICAL DAMAGE CAUSED BY MISUSE OR PHYSICAL ABUSE IS NOT
COVERED UNDER THE WARRANTY. Items such as cables and nonserialized
modules are not covered under this warranty.

Recalibration of instruments is not covered under the warranty.

This warranty gives you specific legal rights, and you may also have other rights
which vary from state to state, province to province, or country to country. This
warranty is limited to repairing the instrument to Fluke Biomedical’s specifica­tions.

Warranty Disclaimer

Should you elect to have your instrument serviced and/or calibrated by someone
other than Fluke Biomedical, please be advised that the original warranty covering
your product becomes void when the tamper-resistant Quality Seal is removed or
broken without proper factory authorization. We strongly recommend, therefore,
that you send your instrument to Fluke Biomedical for factory service and calibra­tion, especially during the original warranty period.

Restocking Charges

Products returned within 30 days of original purchase are subject to a minimum restocking fee of 15
%. Products returned in excess of 30 days after purchase, but prior to 90 days, are subject to a mini­mum restocking fee of 20 %. Additional charges for damage and/or missing parts and accessories will
be applied to all returns.

Return Procedure

All items being returned (including all warranty-claim shipments) must be sent freight-prepaid to our
factory location. When you return an instrument to Fluke Biomedical, we recommend using United
Parcel Service, Federal Express, or Air Parcel Post. We also recommend that you insure your ship­ment for its actual replacement cost. Fluke Biomedical will not be responsible for lost shipments or
instruments that are received in damaged condition due to improper packaging or handling.

Use the original carton and packaging material for shipment. If they are not available, we recommend
the following guide for repackaging:

 Use a double-walled carton of sufficient strength for the weight being shipped.
 Use heavy paper or cardboard to protect all instrument surfaces. Use nonabrasive material

around all projecting parts.

 Use at least four inches of tightly packed, industry-approved, shock-absorbent ma-

terial around the instrument.

Returns for partial refund/credit:

Every product returned for refund/credit must be accompanied by a Return Material Authorization
(RMA) number, obtained from our Order Entry Group at 1-800-648-7952 or 1-425-446-6945.

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.

W X Warning

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.

1-4

Introduction and Specifications
General Safety Information

• 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 open­circuited.

• 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.

1

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.

Electromagnetic Interference and Susceptibility

Like all similar equipment, this equipment generates, uses, and can radiate
radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications.

Operation of this equipment in a residential area could cause interference, in
which case the user will be required to correct the interference and bear any

costs. The limits established by the following organizations are designed to
provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment.

The Analyzer has been tested by independent testing laboratories and found to
meet the following requirements:

EC Directive 89/336/EEC EN 50081-1 Emissions

Radiated Emissions and Line Conducted Emissions. Verification was to the
limits and methods of EN 55011. The device is classified as EN 55011, Group
A.

EC Directive 89/336/EEC EN 50082-1 Immunity

Electrostatic Discharge Susceptibility, Radiated Susceptibility, and Electrical
Fast Transient/Burst Susceptibility. Verification of compliance was conducted
to the limits and methods of EN 50082-1:1992, IEC 1000-4-2; EN 61000-4-3;
IEC 1000-4-4; EN 61000-4-5; EN 61000-4-6; EN 61000-4-11.

USA Federal Communications Commission

This equipment has been found to comply with the limits for a Class A digital
device, pursuant to Part 15 of the FCC Rules.

Canadian Department of Communications

This digital apparatus does not exceed Class A limits for radio emissions from
digital apparatus set out in the Radio Interference Regulations of the Canadian
Department of Communications.
