Introduction
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.

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.

Enables high-accuracy 1-second response time for MIN MAX recording.
Switches between the ranges available for the selected function. To return to
autoranging, hold the button down for 1 second.
Manually selecting a range causes the meter to exit the Touch Hold®, MIN
MAX, and REL (relative) modes.
Touch Hold captures the present reading on the display. When a new, stable
reading is detected, the meter beeps and displays the new reading.
Stops and starts recording without erasing recorded values.
Stops and starts the frequency counter.

only until all display segments turn on (about one second).
Turns the continuity beeper on and off.
On Model 87, switches between 250 µs and 100 ms or 1 s response
times.
Disables the beeper for all functions.
Stores the present reading as a reference for subsequent readings. The
display is zeroed, and the stored reading is subtracted from all
subsequent readings.
For Models 83 and 85, enables zoom mode for the bar graph.
Starts the frequency counter.
Press again to enter duty cycle mode.
Provides >4000 MΩ input impedance for the 400 mV dc range.
