•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

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/μAor Aterminal, 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.
WCaution
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.
Low Pass Filter (87)
The 87 is equipped with an ac low pass filter. When measuring ac voltage
or ac frequency, press Ato activate the low pass filter mode (K).
The Meter continues measuring in the chosen ac mode, but now the signal
diverts through a filter that blocks unwanted voltages above 1 kHz, refer to
Figure 2. The lower frequency voltages pass with reduced accuracy to the
measurement below 1 kHz. The low pass filter can improve measurement
performance on composite sine waves that are typically generated by
inverters and variable frequency motor drives.
XWWarning
To avoid possible electric shock or personal injury, 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.
Note
In Low Pass Mode, the Meter goes to manual mode. Select
ranges by pressing the RANGE button. Autoranging is not
available in Low Pass Mode.

Bar Graph
The analog bar graph functions like the needle on an analog meter, but
without the overshoot. The bar graph updates 40 times per second.
Because the graph responds 10 times faster than the digital display, it is
useful for making peak and null adjustments and observing rapidly
changing inputs. The graph is not shown for capacitance, frequency
counter functions, temperature, or peak min max.
The number of lit segments indicates the measured value and is relative
to the full-scale value of the selected range.
In the 60 V range, for example, the major divisions on the scale represent
0, 15, 30, 45, and 60 V. An input of -30 V lights the negative sign and the
segments up to the middle of the scale.
The bar graph also has a zoom function, as described under “Zoom
Mode” in the Users Manual located on the 80 Series V User Manuals CD.
Table 6. MIN MAX Functions
Button MIN MAX Function
B Enter MIN MAX recording mode. The Meter is locked in the range displayed before you entered MIN MAX mode.
(Select the desired measurement function and range before entering MIN MAX.) The Meter beeps each time a new
minimum or maximum value is recorded.

AutoHOLD Mode
13
AutoHOLD Mode
XWWarning
To avoid electrical shock or personal injury, do not use
AutoHOLD mode to determine that circuits are without
power. The AutoHOLD mode will not capture unstable or
noisy readings.
The AutoHOLD mode captures the present reading on the display. When a
new, stable reading is detected, the Meter beeps and displays the new
reading. To enter or exit AutoHOLD mode, press D.
Relative Mode
Selecting relative mode ( F) causes the Meter to zero the display
and store the present reading as the reference for subsequent
measurements. The Meter is locked into the range selected when you
pressed F. Press Fagain to exit this mode.
In relative mode, the reading shown is always the difference between the
present reading and the stored reference value. For example, if the stored
reference value is 15.00 V and the present reading is 14.10 V, the display
shows -0.90 V.
Maintenance
XWWarning
To avoid electrical shock or personal injury, repairs or
servicing not covered in this manual should be performed
only by qualified personnel as described in the
80 Series V Service Information.
General Maintenance
Periodically wipe the case with a damp cloth and mild detergent. Do not
use abrasives or solvents.
Fuse Test
If a test lead is plugged into the mA/μAor Aterminal and the rotary
switch is turned to a non-current function, the Meter chirps and flashes
“LEAd” if the fuse associated with that current terminal is good. If the
Meter does not chirp or flash “LEAd”, the fuse is bad and must be
replaced.
XWWarning
To avoid electrical shock or personal injury, remove the test
leads and any input signals before replacing the battery or
fuses. To prevent damage or injury, install ONLY specified
replacement fuses with the amperage, voltage, and speed
ratings shown in Replacement Parts in the Users Manual
located on the 80 Series V User Manual CD.

Detailed Specifications
For all detailed specifications:
Accuracy is given as ±([% of reading] + [number of least significant digits]) at 18° C to 28° C, with relative humidity up to 90 %, for a period of one year after
calibration.
For Model 87 in the 4 ½-digit mode, multiply the number of least significant digits (counts) by 10. AC conversions are ac-coupled and valid from 3 % to 100 %
of range. Model 87 is true rms responding. AC crest factor can be up to 3 at full scale, 6 at half scale. For non-sinusoidal wave forms add -(2 % Rdg + 2 % full
scale) typical, for a crest factor up to 3.

between 1 and 30 counts. A 30 count residual reading will cause only a 2-digit change for readings over 3 % of range. Using REL to offset this reading
may produce a much larger constant error in later measurements.
[3] Frequency range: 1 kHz to 2.5 kHz.
[4] A residual reading of up to 13 digits with leads shorted, will not affect stated accuracy above 3 % of range.

1. AC conversion for Model 83 is ac coupled and calibrated to the rms value of a sine wave input.
2. AC conversions for Model 87 are ac coupled, true rms responding, and valid from 3 % to 100 % of range, except 400 mA range (5 % to 100 % of
range) and 10 A range (15 % to 100 % or range).
3. Model 87 is a true rms responding meter. When the input leads are shorted together in the ac functions, the Meter may display a residual reading
between 1 and 30 counts. A 30 count residual reading will cause only a 2 digit change for readings over 3 % of range. Using REL to offset this reading
may produce a much larger constant error in later measurements
4. W10 A continuous up to 35 °C; < 20 minutes on, 5 minutes off at 35 °C to 55 °C. 20 A for 30 seconds maximum; > 10 A unspecified.
5. Below a reading of 200 counts, add 10 counts.
6. 400 mA continuous; 600 mA for 18 hrs maximum.
