Safety Information: Read First

The Fluke 125 ScopeMeter Test Tool (hereafter referred
to as “Test Tool”) complies with:

• ANSI/ISA-82.02.01

• EN/IEC 61010-1: 2001 600 V Measurement

Category III, Pollution Degree 2

• CAN/CSA-C22.2 No.61010-1-04 (including
CSAUS approval)

C

Use the Test Tool only as specified in the Users Manual.
Otherwise, the protection provided by the Test Tool might
be impaired.

A Warning identifies conditions and actions that pose
hazard(s) to the user. A Caution identifies conditions and
actions that may damage the Test Tool.

Getting Started

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.
The 230V rating of the PM8907/808 is not for use in
North America. A line plug adapter complying with the
applicable National Requirements may be provided to
alter the blade configurations for a specific country.

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 125 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 apply input voltages above the rating

of the instrument. Use caution when using 1:1
test leads because the probe tip voltage w ill
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.

Preparing for Use

Max. Input Voltages

Input A and B directly ...............................600 V CAT III

Input A and B via BB120 ..........................300 V CAT III

Input A and B via STL120.........................600 V CAT III

Max. Floating Voltage

From any terminal to ground ....................600 V CAT III

Voltage ratings are given as “working voltage”. They
should be read as Vac-rms (50-60 Hz) for AC sine
wave applications and as Vdc for DC applications.

Measurement Category III refers to distribution level and
fixed installation circuits inside a building.

The isolated input connectors have no exposed metal and
are fully insulated to protect against electrical shock.

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.

Preparing for Use

At delivery, the installed rechargeable batteries may be
empty. To reach full charge they must be charged for 7
hours with the Test Tool turned off:

• use only the supplied Battery Charger/Power Adapter
model PM8907

• before use check that the PM8907 voltage and
frequency range match the local line power range

• connect the battery charger to the ac outlet

• connect the battery charger to the POWER ADAPTER

input on the right-hand side of the Test Tool.

Caution

To prevent decrease of the battery capacity,
you must charge the batteries at least once a
year.

Getting Started

Powering/Resetting the Test Tool

Turning power on/off:

The Test Tool powers up in its last
setup configuration.

Resetting the Test Tool to the factory (default) settings:

+

Turn power off, then press and hold the
Backlight key and turn on again. You
should hear a double beep.

Changing Backlight and Contrast

To save battery power, the screen can be set to an
economic brightness display when operated on the battery
pack (with no power adapter connected).

Note

Using dimmed display lengthens maximum
battery power operation time.

To change the brightness and contrast:

Open the LIGHT/CONTRAST button
bar.

Dim / Brighten the backlight.

Press CONTRAST.
Adjust the Contrast of the display.

Reading the Screen

The screen is divided into three areas that are indicated in
Figure 2. The areas are:

Reading area

only input A is on, you will see the input A readings only. If
input B is on you will also see the input B readings.

Waveform area (B): Displays the Input A(B) waveform.
The trace identifier (A) is visible on the left of the
waveform. The zero icon (-) identifies the ground level of
the waveform. The bottom line displays the ranges / div
and the power indicator (line or battery).

When battery powered, the battery indicator
informs you about the condition of the battery
from full to empty:

(A): Displays the numeric readings. If
