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 three years 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.
