Safety
mm
In this manual, the word “WARNING” identifies
conditions and actions that pose hazard(s) to the
user. The word “CAUTION” refers to conditions
and/or actions that can damage the instrument. Use
of the instrument in a manner not specified may impair safety. Read the following safety information
carefully before attempting to operate or service the
instrument.
• Use caution when working above 60V dc or 30V
ac rms. Such voltages pose a shock hazard.
• When using the probes, keep your fingers away
from probe contacts. Keep your fingers behind
the finger guards on the probes.
• Place test leads in proper input terminals.
• Disconnect the live test lead before disconnect-
ing the common test lead.
• Avoid working alone.
• Disconnect the power and discharge high-
voltage capacitors before testing in Ohms
Continuity, Diode, Capacitance, and COMPONENT Test.
• Inspect the test leads for damaged insulation or
exposed metal. Check test lead continuity.
Damaged leads should be replaced.
• Do not use the GMM if it looks damaged.
• Select the proper function and range for your
measurement.
• When measuring current, turn the power off to
the circuit being tested before connecting the
GMM test tool in that circuit.
• Check GMM test tool fuses before measuring
current transformer secondary or motor winding
current. (See Testing the Fuses in the User
Maintenance chapter.) An open fuse may allow
high voltage buildup, which is potentially hazardous.
• Use clamp-on probes (current clamps) when
measuring currents exceeding 10A.
ix
867B/863
Users Manual
WARNING
m
Hazardous voltages are present on
the External Trigger input terminal
and any attached probe when the
GMM is measuring voltages greater
than 30V rms or 60V dc.
Replacing Fuses
The following fuses should be used:
• F 440 mA, 1000V, Minimum Interrupt Rating
10,000A.
• F 11A, 1000V, Minimum Interrupt Rating
17,000A.
Warning
Use of fuses with voltage ratings
below 1000V reduces protection.
Do not replace the 440 mA 1000V
fuse with a 4/10A 600V fuse.

CHANGE THE DISPLAY MODE
With the GMM still in AC Volts, press first d, then
screen changes to the View Mode, where the entire screen is used for displaying a waveform.
You can repeat this procedure to select any of the display modes available in AC Volts (Combo,
Meter, View, and Trend.) Refer to Table 1-3 for an overview of display modes available in each
function. Examples of all display modes (Combo, Meter, View, Trend, Logic Test, Auto Diode
Test, Component Test, and Sleep) follow this table. Along with the flexibility provided by multiple
softkey definitions, display modes increase the versatility of your GMM considerably.
Many operations activated in one display mode are retained when you select a new mode. For
example, “Rel”, “dB”, Min Max, range, and frequency measurement type are retained.
CHANGE THE FUNCTION
Rotate the selector to DC Volts (E). Observe that the display shifts back to Combo Display Mode.
(This is the default mode, as established on the screen you see when you turn the selector to
SET UP.)
USE THE SOFTKEYS
With DC Volts and Combo Mode still active, you can use the DC Volts Softkeys. For example,

Making Measurements
Note
Recharge the NiCd battery pack before using the 867B. See Battery Considerations in Chapter 3.
Introduction
This chapter shows overall procedures for making
measurements in any of the rotary selector positions.
Necessary input connections are shown. Softkeys
used with each of the display modes available for the
selected function are also shown.
Using the Selector
To begin using the GMM, turn the selector to any
of the indicated functions. Softkey labels
momentarily identify the display modes available for
this function, then proceed to list the softkeys
available with this function.
Softkeys
Any selector setting or hardkey press provides you
with a unique set of softkey labels along the bottom
of the display. These labels define the present uses
for the five blue keys that are positioned immediately
below the display.
In Combo and Meter display modes, some labels are
used with several different selector positions; see
Table 2-1 for descriptions of these common labels.
Other labels are unique for the selector position;
these labels are defined in this chapter as needed.
View and TrendGraph softkey labels are common
for all functions that can use these modes; refer to
Chapter 5 for a full discussion.
Hardkeys
Although hardkeys can generally be pressed at any
time, certain feature combinations are not allowed.
The GMM rejects any hardkey press that is not
allowed and tells you so with a long beep.

Start relative readings in the primary display (REL is displayed). The relative reference (stored
when “Rel” is selected) appears with the softkey.
Peak Hold displays the highest and lowest peak values encountered in the present measurement
function. These values replace either the secondary reading in Meter Mode or the graphical
display in Combo Mode.
Toggle between true “rms” (“rms” annunciator on in display) and “Average” (average responding,
rms indicating - no annunciator) readings in any ac function. The rms/Average selection remains
in effect until you change the selector position. The rms/Average settings made in one display
mode are automatically made for other display modes in the same selector position. “Average” or
“rms” can be set as the standard selection on the SET UP display.
In VDC or mV DC, use the full display to show the numerical “DC” and “AC rms” values. Press
again to return to the original display.
3
Show dBm values in the primary display. The “dB” value shown above this softkey identifies the
resistance used in computing dBm; 600Ω is the standard value. You can change this value from
the SET UP display. (Rotate the selector to SET UP, change the reference selection, then rotate
the selector back to the original ac function.)

Toggle between “DC” and “AC” amps or mAµA measurements. “DC” is the standard
configuration.
Activate the beeper for continuity or Manual Diode testing; a beep then sounds each time the
voltage drop passes below 0.7V (Continuity) or the logic activity indicator flashes (LOGIC
Testing). A short circuit results in a continuous tone. If the reading goes above 30 volts, a
possibly dangerous voltage exists on the inputs but is not displayed. Therefore, the safety
indicator (l) lights.
