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 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 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 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
handling, 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, 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
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 of competent
jurisdiction, such holding will not affect the validity or enforceability of any other
provision.

Safety Information

This meter has been designed and tested in accordance with IEC
Publication 348. To ensure that the meter is used safely, follow all safety
and operating instructions in this manual. If the meter is not used as
described in this manual, the safety features of the meter might be
impaired.

•

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.

1-1. Introduction

Your Fluke Model 8060A is a handheld, microcomputer-based 4½ digit
multimeter that is ideally suited for use in the field, laboratory, shop, or
home. The 8060A has all the features that have become accepted standards
for quality handheld multimeters, as well as some new features that have not
been offered before in a handheld multimeter. New features include the
following:

•

True rms measurements for ac signals up to 100 kHz.

•

Frequency measurements up to 200 kHz.

•

Voltage measurements in dBm referenced to 600Ω or in dB relative to

an operator-selected reference voltage.

•

Resistance measurements up to 300 MΩ.

•

Ability to store any input signal as an offset or relative reference value.

Other features include:

• Functions:

All standard DMM measurement functions, such as ac and dc volts and
ac and dc current, as well as resistance, conductance, continuity, and
diode test.

• Ranges:

Leading zero suppression.
Automatic polarity.
Overrange indication.
Protection from overloads and transients up to 1500V peak.
Dual-slope integration a/d conversion to ensure noise-free

measurements.
Autoranging MΩ resistance range (to 300 MΩ), as well as four fixed

resistance ranges from 200Ω to 200 kΩ.

• Operator Convenience:

4½ digit Liquid Crystal Display.
Software-controlled self-test routines for quick verification of internal

circuitry and operation.

Power:

170 hours of continuous operation can be expected from a 9V alkaline
battery (NEDA 1604).

Low battery voltage is automatically detected and displayed. The low
battery indication, BT, appears on the display when about 20% of the
battery life remains.

A full line of accessories is available to enhance the capabilities of the
8060A.
