Safely Using the Test Tool
Attention
Carefully read the following safety
information before using the test tool.
Safety Precautions
Specific warning and caution statements, where they
apply, will be found throughout the manual.
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.
Symbols used on the test tool and in this manual are
explained in the next table.
Warning
To avoid electrical shock, use only Fluke
power supply, Model PM8907 (Power
Adapter/Battery Charger).

Warning
Should this test tool be used with AC
coupling selected, or manual operation of
amplitude or time base ranges, the measuring
results displayed on the screen may not be
representative of the total signal. This can
result in the presence of dangerous voltages
of more than 42V peak (30V rms), not being
detected. To guarantee user safety, all signals
should first be measured with DC coupling
selected and in fully automatic mode. This
ensures that the full signal content is
measured.

Safely Using the Test Tool
Warning
To avoid electrical shock or fire:
• Use only the power supply, Model PM8907
(Battery Charger / Power Adapter).
• Before use check that the selected/indicated
voltage range on the PM8907 matches the
local line power voltage and frequency.
• For the PM8907/808 universal Battery
Charger/Power Adapter use only line cords
that comply with the local safety regulations.
Note
To accommodate connection to various line
power sockets, the PM8907/808 universal
Battery Charger / Power Adapter is equipped
with a male plug that must be connected to a line
cord appropriate for local use. Since the adapter
is isolated, the line cord does not need to be
equipped with a terminal for connection to
protective ground. Since line cords with a
protective grounding terminal are more
commonly available you might consider using
these anyhow.
Warning
To avoid electrical shock or fire if a Test Tool
input is connected to more than 42 V peak (30
Vrms) or on circuits of more than 4800 VA:
• Use only insulated voltage probes, test leads
and adapters supplied with the Test Tool, or
indicated as suitable for the Fluke 123/124
Test Tool.
• Before use, inspect voltage probes, test leads
and accessories for mechanical damage and
replace when damaged.
• Remove all probes, test leads and
accessories that are not in use.
• Always connect the battery charger first to
the ac outlet before connecting it to the Test
Tool.
• Do not connect the ground wire (Figure 1,
item 5) to voltages higher than 42 V peak (30
Vrms) from earth ground.
• Do not apply input voltages above the rating
of the instrument. Use caution when using
1:1 test leads because the probe tip voltage
will be directly transmitted to the Test Tool.
• Do not use exposed metal BNC or banana
plug connectors.

• Do not insert metal objects into connectors.
• Always use the Test Tool only in the manner
specified.

Voltage ratings are given as “working voltage”. They
should be read as Vac-rms (50-60 Hz) for AC sinewave
applications and as Vdc for DC applications.
Overvoltage Category III refers to distribution level and
fixed installation circuits inside a building.
The terms ‘Isolated’ or ‘Electrically floating’ are used in
this manual to indicate a measurement in which the Test
Tool’s Shielded Banana inputs or banana jack is
connected to a voltage different from earth ground.
If Safety Features are Impaired
Use of the Test Tool in a manner not specified may
impair the protection provided by the equipment.
Before use, inspect the test leads for mechanical damage
and replace damaged test leads!
Whenever it is likely that safety has been impaired, the
Test Tool must be turned off and disconnected from the
line power. The matter should then be referred to qualified
personnel. Safety is likely to be impaired if, for example,
the Test Tool fails to perform the intended measurements
or shows visible damage.
The isolated input connectors have no exposed metal and
are fully insulated to protect against electrical shock.
