LIMITED WARRANTY AND LIMITATION OF LIABILITY

Each Fluke product is warranted to be free from defects in material and workmanship under normal use and

service. The warranty period is one year and begins on the date of shipment. Parts, product repairs, and

services are warranted for 90 days. This warranty extends only to the original buyer or end-user customer of

a Fluke authorized reseller, and does not apply to fuses, disposable batteries, or to any product which, in

Fluke's opinion, has been misused, altered, neglected, contaminated, or damaged by accident or abnormal

conditions of operation or handling. Fluke warrants that software will operate substantially in accordance with

its functional specifications for 90 days and that it has been properly recorded on non-defective media. Fluke

does not warrant that software will be error free or operate without interruption.

Fluke authorized resellers shall extend this warranty on new and unused products to end-user customers

only but have no authority to extend a greater or different warranty on behalf of Fluke. Warranty support is

available only if product is purchased through a Fluke authorized sales outlet or Buyer has paid the

applicable international price. Fluke reserves the right to invoice Buyer for importation costs of

repair/replacement parts when product purchased in one country is submitted for repair in another country.

Fluke's warranty obligation is limited, at Fluke's option, to refund of the purchase price, free of charge repair,

or replacement of a defective product which is returned to a Fluke authorized service center within the

warranty period.

To obtain warranty service, contact your nearest Fluke authorized service center to obtain return

authorization information, then send the product to that service center, with a description of the difficulty,

postage and insurance prepaid (FOB Destination). Fluke assumes no risk for damage in transit. Following

warranty repair, the product will be returned to Buyer, transportation prepaid (FOB Destination). If Fluke

determines that failure was caused by neglect, misuse, contamination, alteration, accident, or abnormal

condition of operation or handling, including overvoltage failures caused by use outside the product’s

specified rating, or normal wear and tear of mechanical components, Fluke will provide an estimate of repair

costs and obtain authorization before commencing the work. Following repair, the product will be returned to

the Buyer transportation prepaid and the Buyer will be billed for the repair and return transportation charges

(FOB Shipping Point).

THIS WARRANTY IS BUYER'S SOLE AND EXCLUSIVE REMEDY AND IS IN LIEU OF ALL OTHER

WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY IMPLIED WARRANTY

OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. FLUKE SHALL NOT BE LIABLE

FOR ANY SPECIAL, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OR LOSSES,

INCLUDING LOSS OF DATA, ARISING FROM ANY CAUSE OR THEORY.

Since some countries or states do not allow limitation of the term of an implied warranty, or exclusion or

limitation of incidental or consequential damages, the limitations and exclusions of this warranty may not

apply to every buyer. If any provision of this Warranty is held invalid or unenforceable by a court or other

decision-maker of competent jurisdiction, such holding will not affect the validity or enforceability of any other

provision.

INTERFERENCE INFORMATION

This equipment generates and uses radio frequency energy and if not installed and used in strict

accordance with the manufacturer's instructions, may cause interference to radio and television

reception. It has been type tested and found to comply with the limits for a Class B digital device in

accordance with the specifications of Part 15 of FCC Rules, which are designed to provide

reasonable protection against such interference in a residential installation.

Operation is subject to the following two conditions:

•This device may not cause harmful interference.

•This device must accept any interference received, including interference that may cause

undesired operation.

There is no guarantee the interference will not occur in a particular installation. If this equipment

does cause interference to radio or television reception, which can be determined by turning the

equipment off and on, the user is encouraged to try to correct the interference by one or more of

the following measures:

•Reorient the receiving antenna

•Relocate the equipment with respect to the receiver

•Move the equipment away from the receiver

•Plug the equipment into a different outlet so that the computer and receive are on different

branch circuits

If necessary, the user should consult the dealer or an experienced radio/television technician for

additional suggestions. The user may find the following booklet prepared by the Federal

Communications Commission helpful: How to Identify and Resolve Radio-TV Interference

Problems. This booklet is available from the U.S. Government Printing Office, Washington, DC

20402. Stock No. 004-000-00345-4.

SAFETY TERMS IN THIS MANUAL

This instrument has been designed and tested in accordance with IEC publication

1010-1 (1992-1), Safety Requirements for Electrical Measuring, Control and Laboratory

Equipment, and ANSI/ISA-S82.01-1994, and CAN/CSA-C22.2 No. 1010.1-92. This User

Manual contains information, warning, and cautions that must be followed to ensure safe

operation and to maintain the instrument in a safe condition. Use of this equipment in a

manner not specified herein may impair the protection provided by the equipment.

This instrument is designed for IEC 1010-1 Installation Category II use. It is not designed

for connection to circuits rated over 4800 VA.

WARNING statements identify conditions or practices that could result in personal injury

or loss of life.

CAUTION statements identify conditions or practices that could result in damage to

equipment.

SYMBOLS MARKED ON EQUIPMENT

WARNING Risk of electric shock. Refer to the manual (see the Index for

references).

GROUND Ground terminal to chassis (earth).

Attention Refer to the manual (see the Index for references). This

symbol indicates that information about usage of a feature is contained in

the manual.

AC POWER SOURCE

The instrument is intended to operate from an ac power source that will not apply more

than 264V ac rms between the supply conductors or between either supply conductor

and ground. A protective ground connection by way of the grounding conductor in the

power cord is required for safe operation.

USE THE PROPER FUSE

To avoid fire hazard, for fuse replacement use only the specified unit: 100 or 120 V

operation, 2 ampere/250 volt time delay; 200 or 240 V operation, 1 ampere/250 volt time

delay.

GROUNDING THE INSTRUMENT

The instrument utilizes controlled overvoltage techniques that require the instrument to

be grounded whenever normal mode or common mode ac voltages or transient voltages

may occur. The enclosure must be grounded through the grounding conductor of the

power cord, or through the rear panel ground binding post.

USE THE PROPER POWER CORD

Use only the power cord and connector appropriate for the voltage and plug

configuration in your country.

Use only a power cord that is in good condition.

Refer power cord and connector changes to qualified service personnel.

DO NOT OPERATE IN EXPLOSIVE ATMOSPHERES

To avoid explosion, do not operate the instrument in an atmosphere of explosive gas.

DO NOT REMOVE COVER DURING OPERATION

To avoid personal injury or death, do not remove the instrument cover without first

removing the power source connected to the rear panel. Do not operate the instrument

without the cover properly installed. Normal calibration is accomplished with the cover

closed. Access procedures and the warnings for such procedures are contained both in

this manual and in the Service Manual. Service procedures are for qualified service

personnel only.

DO NOT ATTEMPT TO OPERATE IF PROTECTION MAY BE IMPAIRED

If the instrument appears damaged or operates abnormally, protection may be impaired.

Do not attempt to operate the instrument under these conditions. Refer all questions of

proper instrument operation to qualified service personnel.
