NOTICE
The Fluke 87 generates and uses radio frequency energy. If it is not used according to the
Instructions in this manual, it may cause interference to radio and television reception. The
Fluke 87 has been type tested and found to comply with the limits for aclass Bcomputing
device in accordance with the specifications in Subpart Jof Part 15 of FCC rules, which are
designed to provide reasonable protection against such interfence in aresidential location.
However, there Is no guarantee that interference will not occur in aparticular location. If this
equipment does cause Interference, which can be determined by turning the Fluke 87 off and
on, the user is encouraged to try to correct the interference by one or more of the following
measures:
•Move the Fluke 87 away from the receiver.
•If necessary, the user should consult the dealer or an experienced radio/television
technician for additional suggestions.

INTRODUCTION
INTRODUCTION
NOTE
This meter has been designedand tested according to
IEC Publication 348, Safety Requirementsfor Elec-
tronic Measuring Apparatus. This manual contains
information and warnings which must befollowed
to ensure safe operation and retain the meter in safe
condition.
WARNING
READ "MULTIMETER SAFETY" BEFORE
USING THE METER.
The Fluke 87 True RMS Multimeter (also referred to as "the
meter") is ahandheld, 4000-count instrument that is designed
for use in the field, laboratory, and at home. The meter com-
bines the precision of adigital meter with the speed and versa-
tility of ahigh resolution analog display. Frequencies between
0.5 Hz and 200 kHz can be measured with up to 0.01 Hz resolu-
tion. The meter is powered by a9V battery and has arugged
case sealed against dirt, dust and moisture. Asnap-on holster,
with flexible stand (Flex-Stand™), protects the meter from
rough handling. The flexible stand allows the meterto be stood
or hung.
The meter also provides:
•AMIN MAX Recording mode, in which the meter
"remembers" the lowest and highest readings, calcu-
lates the true average of all readings taken over a
period as long as thirty-six hours, and displays these
values. The beeper emits aMin Max Alert™ when a
new minimum or maximum reading is recorded.
•APeak MIN MAX mode that captures changes as short
as 1millisecond.
•An alternate Frequency Counter mode that measures
duty cycle and displays it as avalue between 0.0 and
99.9%.
•An Input Alert™ that causes the beeper to sound if the
test leads are plugged into the wrong input terminals for
the function being performed.
•AREL mode that allows you to store areading in
memory, and display the difference between the stored
value and subsequent readings.
•ATouch Hold® mode that allows you to keep your eyes
fixed on the probes when taking measurements in diffi-
cult or hazardous circumstances, then read the display
when it is convenient and safe.

MULTIMETER SAFETY
•Adisplay back-light that makes the meter useable in
dark areas.
•A41/2-digit display mode for ten times increase in
resolution.
•ACapacitance mode that measures capacitors from
0.01 nFto5//F.
After unpacking the meter, if you notice that the meter is dam-
aged or something is missing, contact the place of purchase
immediately. Save the shipping container and packing mate-
rial in case you have to reship the meter.
MULTIMETER SAFETY
Before usings the meter, read the following safety information
carefully. Inthis manualtheword, "WARNING," is reserved for
conditions and actions that pose hazard(s) to the user; the
word, "CAUTION," is reserved for conditions and actions that
may damage your meter. The symbols shown in Figure 1are
used internationally to denote the electrical functions and
conditions indicated. If the meter is not used as described in
this manual, the safety features of the meter might be impaired.
•Avoid working alone.
•Do not allow the meter to be used if it is damaged, or its
safety is impaired.

Inspect the test leads for damaged insulation or exposed
metal. Check test lead continuity. Damaged leads should
be replaced.
Be sure the meter is in good operating condition. During
acontinuity test, a meter reading that goes from over-
load (OL) to generally means the meter is working
properly.
Select the proper function and range for your
measurement

•Disconnect the live test lead before disconnecting the
common test lead.
•Follow all safety procedures for equipment being tested.
Disconnect the input power and discharge all high-
voltage capacitors through aprotective impedance
before testing in the Oand -w- functions.
•When making acurrent measurement turn the power
off before connecting the meter in the circuit.
•Check meter fuses before measuring current trans-
former secondary or motor winding current (See "Fuse
Test" in the "MAINTENANCE" Section.) An open fuse
may allow high voltage build-up, which is potentially
hazardous.
GETTING STARTED QUICKLY
Examine the meter carefully, familiarizing yourself with the
layout of the input terminals, rotary switch, pushbuttons and
display. Notice the WARNING information and summary of
power-on options engraved into the rear panel.
If you have used amultimeter before, simply examining your
meter will probably give you agood idea how to use it. The
following procedure is an overview of how to take basic
measurements.
GETTING STARTED QUICKLY
WARNING
TO AVOID ELECTRICAL SHOCK OR DAMAGE
TO THE METER, DO NOT APPLY MORE THAN
1000V BETWEEN ANY TERMINAL AND EARTH
GROUND.
1. Insert the test leads in the appropriate input terminals
(see Table 1). If the test leads are in the wrong input ter-
minals when the meter is turned on and the beeper has
not been disabled, the beeper will emit awarning. See
"Input Terminals and Input Alert", below.
2. To turn the meter on and select afunction, turn the rotary
switch from OFF to the appropriate switch position. All
segments on the liquid -crystal display (LCD) will turn on
for one second, then the meter is ready for normal oper-
ation. If you would like to freeze the display with all seg-
ments on, press and hold down any button, while turning
the meter on. As long as the button is held down, all LCD
segments will remain on.
3. To select an additional operation, press the appropriate
pushbuttons above the rotary switch as described in the
items below. (See also, Figure 2.)

HOW TO USE THE METER
•To operate the MIN MAX and RANGE buttons: press to
select, press again to scroll or increment, and press and
hold for two seconds to exit.
•To operate the Hz button: press to select the frequency
mode, press again to select duty cycle, and press again
to exit.
•To operate the back-lit display, press the YELLOW but-
ton. The back-light automatically turns off in 68 seconds
to conserve battery life.
•To operate the remaining buttons: press to select and
press again to exit.
NOTE
The response of the display and the pushbuttons
slows down in the capacitance mode.
An annunciator is displayed when amode has been selected.
Aquick way to reset all the pushbuttons to their default state is
to turn the rotary switch to an adjacent function and then back
to the function you are using.
4. To take ameasurement, use the test lead probes to make
the proper contacts. Remember, insert the meter in the
circuit in parallel for voltage and in series for current
4
measurements. Read the measurement on the display. If
you did not manually select arange (by using the
RANGE button), the rangethat provides the best resolu-
tion is automatically selected.
5. To run aperformance check of the meter, turn the
rotary switch to Qarid connect atest lead from the
VO-w-input to the mA //A input. (If you are using atest
probe, touch the half of the input contact nearest the
LCD.) The display should read 1.000 kQ ±5digits. With
the rotary switch still at Q, test the Afuse (15A) by
inserting the plug end of the test lead into the Ainput
and test the mA //A fuse (1 A) by inserting the plug end
of the test lead into the mA fjA input. The beeper emits
an Input Alert if the fuses are good.
Although this procedure will allow you to get started quickly,
we suggest that you take the time to read the remainder of this
manual so that you can learn to take full advantage of your
meter's capabilities.
