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 or damaged by accident or
abnormal conditions of operation or handling. Fluke warrants that software will oper-
ate 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 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 coun-
try.
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 or
send the product, with a description of the difficulty, postage and insurance prepaid
(FOB Destination), to the nearest Fluke authorized service center. 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 the failure
was caused by misuse, alteration, accident or abnormal condition of operation or han-
dling, 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 transporta-
tion 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, IN-
CLUDING LOSS OF DATA, WHETHER ARISING FROM BREACH OF WARRANTY
OR BASED ON CONTRACT, TORT, RELIANCE OR ANY OTHER THEORY.
Since some countries or states do not allow limitation of the term of an implied war-
ranty, 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 of competent jurisdiction, such
holding will not affect the validity or enforceability of any other provision.

Do not use the meter if the meter or test leads look damaged, or if you
suspect that the meter is not operating properly.
Turn off power to the circuit under test before cutting, unsoldering, or
breaking the circuit. Small amounts of current can be dangerous.
Do not apply more than 500V rms between a terminal and earth ground.
Use caution when working above 60V dc or 30V ac rms. Such voltages
pose a shock hazard.
When using the probes, keep your fingers behind the finger guards on
the probes.
Disconnect the live test lead before disconnecting the common test lead.
