WARNING
READ "SAFETY" CAREFULLY BEFORE USING YOUR
SCOPEMETER TEST TOOL.
SAFETY
The instrument described in this manual is designed to be
used only by qualified personnel.
Safety Precautions
To use this instrument safely, it is essential that operating
and servicing personnel follow both generally accepted
safety procedures and the safety precautions specified in
this manual.
Specific warning and caution statements, where they
apply, will be found throughout the manual.
Where necessary, the warning and caution statements
and/or symbols are marked on the instrument.
A CAUTION identifies conditions and actions that may
damage the test tool.
A WARNING IDENTIFIES CONDITIONS AND ACTIONS
THAT POSE HAZARD(S) TO THE USER.
International electrical symbols used are explained below.
The terms "Isolated" or "Electrically floating" are used in
this manual to indicate a measurement in which the
ScopeMeter test tool COM (common, also called ground) is
connected to a voltage different from earth ground. The
term "Grounded" is used in this manual to indicate a
measurement in which the ScopeMeter test tool COM
(common) is connected to an earth ground potential.
The ScopeMeter test tool COM (common) inputs (red
INPUT A BNC shield, grey INPUT B BNC shield, and black
4-mm banana jack) are connected internally via self-
recovering fault protection. The input connectors have no
exposed metal and are fully insulated to protect against
electrical shock. The black 4-mm banana jack COM
(common) can be connected to a voltage above earth
ground for isolated (electrically floating) measurements

and is rated up to 600V rms above earth ground. The ScopeMeter test tool uses a three-lead connection sys-
tem for dual input, isolated (electrically floating) measure-
ments. The connections for isolated and grounded
measurements are shown in the following illustration.

NOTE
Fluke 91 has a two lead connection system.

X91/92/96/99/105 Users Manual
WARNING
DO THE FOLLOWING TO AVOID ELECTRICAL SHOCK
IF A SCOPEMETER TEST TOOL COM (COMMON)
INPUT IS CONNECTED TO >42V PEAK (30V RMS):
1. USE ONLY THE TEST LEAD/PROBE SET SUPPLIED
WITH THE SCOPEMETER TEST TOOL (OR
SAFETY-DESIGNED EQUIVALENTS WITHOUT
EXPOSED METAL CONNECTORS).
2. DO NOT USE CONVENTIONAL EXPOSED METAL
BNC OR BANANA PLUG CONNECTORS IF THE
COM (COMMON) IS >42V PEAK (30V RMS).
3. USE ONLY ONE COM (COMMON) CONNECTION
(THE 4-MM BLACK BANANA JACK).
4. REMOVE ALL PROBES AND TEST LEADS THAT
ARE NOT IN USE.
5. USE 600V RATED PROBE TIP ADAPTERS.
"600V" IS PRINTED ON EQUIPMENT SO RATED.
6. CONNECT THE PM8907 POWER ADAPTER TO THE
AC OUTLET BEFORE CONNECTION TO THE
SCOPEMETER TEST TOOL.

XI
If Safety-Protection is Impaired
Use of equipment in a manner not specified may
impair the protection provided by the equipment.
Before use, inspect probes for mechanical damage
and replace damaged probes!
Whenever it is likely that safety has been impaired, the
instrument must be turned off and disconnected from line
power. The matter should then be referred to qualified
personnel. Safety is likely to be impaired if, for example,
the instrument fails to perform the intended measurements
or shows visible damage.
MAKING ISOLATED MEASUREMENTS
Isolating from Earth Ground
The ScopeMeter test tool uses a three-lead connection
system for dual input, isolated (electrically floating)
measurements. Use a test lead connected to the black 4-mm
banana jack as common ground.
There are only three wires to connect for dual input isolated
ground operation, useful for three-phase industrial voltage
measurements. You can connect the three leads on the
test tool (INPUT A, INPUT B, and common) to a three-
phase electrical power line in any order. Use the A-B mode
(see Chapter 5) to display all three phases of electrical
power at the same time.
For three-phase electrical or other isolated ground
industrial measurements, we strongly recommend that you
use the black Industrial Alligator Clip and the red and grey
Industrial Probe Alligator Clips (see Figure 4). These parts
are included with original purchase ScopeMeter test tools
and are also available as accessories from your FLUKE
representative.
Isolating from Input to Input
The ScopeMeter test tool is not isolated between inputs but
uses the black 4-mm banana jack for measurements
isolated from earth ground.
Complete isolation between INPUT A and INPUT B is
useful for some floating measurement applications, such
as measuring different isolated transformer windings at the
same time.
For those applications requiring true isolated grounds
(commons) between inputs, we recommend that you make
two separate measurements or use two ScopeMeter test
tools.

PREPARING TO USE THE DEMONSTRATION (DEMO) BOARD
A Demo Board with 9V battery is included in your ScopeMeter test tool kit. It generates different types of waveforms that can
be measured at test points TP1 to TP5. All descriptions and measurement examples refer to a waveform that can be
measured on the Demo Board.
Do not connect the Demo Board yet, but when you make measurements, do the following:
•Place the Demo Board on a non-conductive surface.
•Connect the 9-volt battery, and make sure that polarity is correct.
The displays and measurements shown in this manual are typical. They will vary depending on the condition of the Demo
Board battery.
