Introduction
XWWarning
Read "Safety Information" before you use the
Meter.
Except where noted, the descriptions and instructions in
this manual apply to Series V Models 83 and 87
multimeters (hereafter referred to as “the Meter”).
Model 87 appears in all illustrations.

80 Series V
Users Manual
Safety Information
The Meter complies with:
• EN61010-1:2001
• ANSI/ISA S82.01-2004
• CAN/CSA C22.2 No. 1010.1:2004
• UL610101-1
• Measurement Category III, 1000V, Pollution
Degree 2
• Measurement Category IV, 600V, Pollution
Degree 2
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.
Electrical symbols used on the Meter and in this manual
are explained in Table 1.
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 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 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.

Safety Information
• 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 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
by the 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.
• 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. First, make a
voltage measurement without the filter to
detect the possible presence of
hazardous voltage. Then select the filter
function.

WCaution
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 all measurements.
• Before measuring current, check the
Meter's fuses. (See "Fuse Test".)

Making Measurements
Power-Up Options
Holding a button down while turning the Meter on activates
a power-up option. Table 4 includes the power-up options.
Automatic Power-Off
The Meter automatically turns off if you do not turn the
rotary switch or press a button for 30 minutes. If MIN MAX
Recording is enabled, the Meter will not power off. To
disable automatic power-off, refer to Table 4.
Input Alert Feature
If a test lead is plugged into the mA/µA or A terminal, but
the rotary switch is not set to the correct current position,
the beeper warns you by making a chirping sound and the
display flashes “LEAd”. 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.
W Caution
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 the Meter.
Measuring AC and DC Voltage
Model 87 features true rms readings, which are accurate
for distorted sine waves and other waveforms (with no dc
offset) such as square waves, triangle waves, and
staircase waves.
The Meter's voltage ranges are 600.0 mV, 6.000 V,
60.00 V, 600.0 V, and 1000 V. To select the 600.0 mV dc
range, turn the rotary switch to mV.
To measure ac or dc voltage, refer to Figure 2.
