Lifetime Limited Warranty

Each Fluke 20, 70, 80, 170 and 180 Series DMM will be free from defects in material and workmanship for
its lifetime. As used herein, “lifetime” is defined as seven years after Fluke discontinues manufacturing the
product, but the warranty period shall be at least ten years from the date of purchase. This warranty does
not cover fuses, disposable batteries, damage from neglect, misuse, contamination, alteration, accident or
abnormal conditions of operation or handling, including failures caused by use outside of the product’s
specifications, or normal wear and tear of mechanical components. This warranty covers the original
purchaser only and is not transferable.

For ten years from the date of purchase, this warranty also covers the LCD. Thereafter, for the lifetime of
the DMM, Fluke will replace the LCD for a fee based on then current component acquisition costs.

To establish original ownership and prove date of purchase, please complete and return the registration card
accompanying the product, or register your product on http://www.fluke.com. Fluke will, at its option, repair
at no charge, replace or refund the purchase price of a defective product purchased through a Fluke
authorized sales outlet and at the applicable international price. Fluke reserves the right to charge for
importation costs of repair/replacement parts if the product purchased in one country is sent for repair
elsewhere.

If the product is defective, 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. Fluke will pay return
transportation for product repaired or replaced in-warranty. Before making any non-warranty repair, Fluke
will estimate cost and obtain authorization, then invoice you for repair and return transportation.

THIS WARRANTY IS YOUR ONLY REMEDY. NO OTHER WARRANTIES, SUCH AS FITNESS FOR A
PARTICULAR PURPOSE, ARE EXPRESSED OR IMPLIED. 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. AUTHORIZED RESELLERS ARE NOT
AUTHORIZED TO EXTEND ANY DIFFERENT WARRANTY ON FLUKE’S BEHALF. Since some states do
not allow the exclusion or limitation of an implied warranty or of incidental or consequential damages, this
limitation of liability may not apply to you. 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.

performing the verification tests or calibration adjustment
procedures documented in this manual.

• Do not perform the verification tests or calibration
adjustment procedures described in this manual unless you
are qualified to do so.

• The information provided in this manual is for the use of
qualified personnel only.

• The 80 Series V Digital Multimeters contains parts that can
be damaged by static discharge.

• Follow the standard practices for handling static sensitive
devices.

The 80 Series V Calibration Manual provides the following information:

Calibration Manual

Precautions and Safety Information

XWWarning

To avoid possible electric shock or personal injury, inspect the
test leads for damaged insulation or exposed metal. Check the
test leads for continuity. Replace damaged test leads before
using the Meter.

In this manual, a Warning identifies conditions and actions that pose hazard(s) to the
user; a Caution identifies conditions and actions that may damage the Meter or the test
instruments.

XWWarning

To avoid possible electric shock or personal injury, follow these
guidelines:

• Use this Meter only as specified in this manual or the
protection provided by the Meter might be impaired.

• Do not use the Meter if it is damaged. Before using the
Meter, inspect the case. Look for cracks or missing plastic.
Pay particular attention to the insulation surrounding the
connectors.

• Make sure the battery door is closed and latched before
operating the Meter.

• Replace the battery as soon as the battery indicator (M)
appears.

• Remove test leads from the Meter before opening the
battery door.

• Inspect the test leads for damaged insulation or exposed
metal. Check the test leads for continuity. Replace damaged
test leads before using the Meter.

• Do not apply more than the rated voltage, as marked on the
Meter, between the terminals or between any terminal and
earth ground.

• Never operate the Meter with the cover removed or the case
open.

• Use caution when working with voltages above 30 V ac rms,
42 V ac peak, or 60 V dc. These voltages pose a shock
hazard.

• Use only the replacement fuses specified in this manual.

• Use the proper terminals, function, and range for

measurements.

• Avoid working alone.

• When measuring current, turn off circuit power before

connecting the Meter in the circuit. Remember to place the
Meter in series with the circuit.

Digital Multimeter

Precautions and Safety Information

• When making electrical connections, connect the common
test lead before connecting the live test lead; when
disconnecting, disconnect the live test lead before
disconnecting the common test lead.

• Do not use the Meter if it operates abnormally. Protection
may be impaired. When in doubt, have the Meter serviced.

• Do not operate the Meter around explosive gas, vapor, or
dust.

• Use only a single 9 V battery, properly installed in the Meter
case, to power the Meter.

• When servicing the Meter, use only specified replacement
parts.

• When using probes, keep fingers behind the finger guards
on the probes.

• Do not use the Low Pass Filter option to verify the presence
of hazardous voltages. Voltages greater than what is
indicated may be present. Make a voltage measurement
without the filter to detect the possible presence of
hazardous voltage, then select the filter function.

XCaution

To avoid possible damage to the Meter or to the equipment
under test, follow these guidelines:

• Disconnect circuit power and discharge all high-voltage
capacitors before testing resistance, continuity, diodes, or
capacitance.

• Before measuring current, check the Meter's fuses.
See " Testing the Fuses”.
