Limited Warranty & 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.
