mmSafety
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 im-
pair safety. Read the following safety information
carefully before attempting to operate or service the
instrument.
• Avoid working alone.
• Disconnect the power and discharge high-
voltage capacitors before testing in Ohms
Continuity, Diode, Capacitance, and COMPO-
NENT 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.
• 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.
• 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 haz-
ardous.
• Use clamp-on probes (current clamps) when
measuring currents exceeding 10A.

867B/863

mWARNING 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.
$WARNING risk of electric shock.
mCAUTION see explanation in manual.
sEquipment protected throughout by DOUBLE
INSULATION or REINFORCED INSULA-
TION.
mmOverload Protection
Voltage or Current Input: 1000V

TURN THE GMM ON BY ROTATING THE SELECTOR TO ANY FUNCTION. Turn the rotary
selector to the AC Volts (v)position. The input connections screen appears for a few seconds,
then the screen sets up for this function, and you are ready to begin. You can toggle the backlight
power level (Model 867B only) by pressing W. Also note that the screen goes dark if you do not
change any controls for about 20 minutes and the GMM is on battery power; pressing Wwakes
up the screen (all models.)

THE SCREEN. In AC Volts, the initial screen presents a primary display of large digits, a
secondary display of smaller digits, and a graphical window showing either a waveform or an
analog NeedleGraphrepresentation of the primary display. In addition, the upper screen line
displays status information. The bottom screen line (immediately above the softkey labels) shows
the display mode, range, and other information. For example, “Combo” appears on this line if a
waveform appears in the graphical window: the GMM is in Combo Mode.

THE SOFTKEYS. Most control settings (selector change or key press) change the softkey labels
along the bottom of the screen. These labels define the present uses for the five blue keys that
are positioned immediately below the screen. Together, the labels and the keys form a set of
Softkeys. These changing softkey definitions allow direct access to a wealth of GMM capabilities.
Refer to Figures 1-6, 1-7, and 1-8 at the end of this chapter for a roadmap to softkey use.

THE HARDKEYS. Hardkeys appear immediately belowthe softkeys. Hardkeys perform the same
operations in all functions. Pressing Wwakes up the screen from Sleep Mode (all models) and toggles
the backlight power level on Model 867B. Although hardkeys can generally be pressed at any time,
certain feature combinations are not allowed. The GMM test tool rejects any hardkey press that is not
allowed; a long beep sounds. Chapter 4 explains each hardkey in detail.

MEASUREMENT CONNECTIONS. Review the input connection scheme now only for
familiarization: no actual connections are necessary during the Quick Tour. Volts, Ohms,
Continuity, Conductance, Diode Test, Capacitance, and Component Test measurements use
Vfor the Red lead. Amps measurements use Afor the Red lead. mAµA measurements
use afor the Red lead. LOGIC Test measurements use Xfor the Red lead. All
functions use Cfor the Black lead. Refer to Figure 1-3 for TL70A test lead connection
views.
FBLINE POWER OR BATTERY POWER. You can power the GMM with batteries or from ac line
power through the Battery Eliminator. New alkaline (AA) cells provide a minimum of 4 hours
operation. A fully charged BP7217 NiCd battery pack typically provides a minimum of 8 hours
operation. The battery eliminator recharges the NiCd battery pack on Model 867B. Refer to
Figure 1-4.
GRS232 SERIAL PC OR PRINTER CONNECTION. Your GMM can use an optional optical serial
interface cable to communicate with a PC or printer. Refer to Chapter 6.

STEP ACTION DESCRIPTION
1dCHANGE THE DISPLAY MODE
With the GMM still in AC Volts, press first d, then 3to change the display mode. The
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.
2JCHANGE 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.)
31USE THE SOFTKEYS
With DC Volts and Combo Mode still active, you can use the DC Volts Softkeys. For example,
press 1to activate “Rel”: difference readings only are now displayed. Press 1 again to
deactivate “Rel”. Explore all five softkeys in this fashion. Press a key first to activate a selection
(label highlighted) and second to disable the selection.

The frequency reading (which was in the secondary display) and DC Volts reading (which was in
the primary display) are swapped.
The softkeys allow you to select different types of frequency measurements (Hz, Duty Cycle,
Pulse Width, or Period). Press 4to select “Period”, then press Fagain to return to the DC
Volts Softkeys. Primary and secondary displays swap again, and the change to “Period” frequency
measurement continues in the secondary display.
