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

Introduction

WWarning

Read "Safety Information" before you use the

meter.

Except where noted, the descriptions and instructions in

this manual apply to Series III Models 83, 85, 87, and

87/E multimeters. Model 87 is shown in all illustrations.

Safety Information

This meter complies with:

• EN61010.1:1993

• ANSI/ISA S82.01-1994

• CAN/CSA C22.2 No. 1010.1-92

• 1000 V Overvoltage Category III, Pollution Degree 2

• UL3111-1

Use the meter only as specified in this manual, otherwise

the protection provided by the meter may be impaired.

In this manual, a Warning identifies conditions and

actions that pose hazards to the user. A Caution

identifies conditions and actions that may damage the

meter or the equipment under test.

International symbols used on the meter and in this

manual are explained in Table 1.

WWarning

To avoid possible electric shock or personal

injury, follow these guidelines:

• Do not use the meter if it is damaged.

Before you use 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 you operate the meter.

• Replace the battery as soon as the

battery indicator (M) appears.

AC or DC Conforms to European Union directives

Refer to the manual for information

about this feature.

Conforms to relevant Canadian

Standards Association directives

Battery Double insulated

Inspected and licensed by TÜV Product Services.

Safety Information

• Remove test leads from the meter before

you open the battery door.

• Inspect the test leads for damaged

insulation or exposed metal. Check the

test leads for continuity. Replace

damaged test leads before you use the

meter.

• 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.

Caution

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.

• Use the proper terminals, function, and

range for your measurements.

• Before measuring current, check the

meter’s fuses. (See "Testing the Fuses".)

80 Series III

Users Manual

To protect yourself, use the following guidelines:

• Use caution when working with voltages above 30 V

ac rms, 42 V ac peak, or 60 V dc. Such voltages

pose a shock hazard.

• When using the probes, keep your fingers behind the

finger guards.

• Connect the common test lead before you connect

the live test lead. When you disconnect test leads,

disconnect the live test lead first.

• 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.

Power-Up Options

Holding a button down while turning the meter on

activates a power-up option. Table 4 includes the power-

up options available. These options are also listed on the

back of the meter.

Automatic Power-Off

The meter automatically turns off if you do not turn the

rotary switch or press a button for 30 minutes. To disable

automatic power-off, hold down the blue button while

turning the meter on. Automatic power-off is always

disabled in MIN MAX recording mode.

80 Series III

Users Manual

Input Alert™ Feature

If a test lead is plugged into the mA/µA or A terminal, but

the rotary switch is not correctly set to the mA/µA or A

position, the beeper warns you by making a chirping

sound. This warning is intended to stop you from

attempting to measure voltage, continuity, resistance,

capacitance, or diode values when the leads are plugged

into a current terminal.

Placing the probes across (in

parallel with) a powered circuit when a lead is plugged into

a current terminal can damage the circuit you are testing

and blow the meter’s fuse.

This can happen because the

resistance through the meter’s current terminals is very

low, so the meter acts like a short circuit.

Making Measurements

The following sections describe how to take

measurements with your meter.

Measuring AC and DC Voltage

Voltage is the difference in electrical potential between

two points. The polarity of ac (alternating current) voltage

varies over time, while the polarity of dc (direct current)

voltage is constant over time. The meter presents ac

voltage values as rms (root mean square) readings. The

rms value is the equivalent dc voltage that would produce

the same amount of heat in a resistance as the measured

sinewave voltage. Models 85 and 87 feature true rms

readings, which are accurate for other wave forms (with

no dc offset) such as square waves, triangle waves, and

staircase waves.

The meter’s voltage ranges are 400 mV, 4 V, 40 V, 400 V,

and 1000 V. To select the 400 mV dc range, turn the

rotary switch to mV.

To measure ac or dc voltage, set up and connect the

meter as shown in Figure 2.
