Getting Started

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 CCSAUS approval)

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.

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 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 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.

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.

Press LIGHT.

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 (A): Displays the numeric readings. If 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).

Note:

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