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 selfrecovering 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.
IX
The ScopeMeter test tool uses a three-lead connection system for dual input, isolated (electrically floating) measurements. The connections for isolated and grounded measurements are shown in the following illustration.
Figure 1. Common (Ground) Connections |
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.

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 threephase 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.

POWERING THE SCOPEMETER TEST TOOL
The test tool can be powered from any of the following sources. Refer to Figure 1-2.
•Internal Battery Pack (PM9086)
A rechargeable NiCad Battery Pack comes installed in every test tool.
•C Cell Batteries
You can use four alkaline batteries in place of the NiCad Battery Pack. (The charger is defeated when standard C cells are installed).
•Power Adapter (PM8907)
The Power Adapter/Battery Charger powers the test tool from a standard ac outlet. The test tool can be used during battery charging. Verify that your local line voltage is appropriate before using the Power Adapter/Battery Charger to power the test tool and/or charge the battery pack.
See Appendix 9C for more information.
•Automotive Adapter (PM9087, optional)
The Automotive Adapter powers and charges from a standard 12V dc automotive accessory (lighter) outlet.
Refer to Chapter 8 for battery replacement instructions.

MINIMIZING SIGNAL NOISE
In general, using your test tool on battery power only will minimize noise pickup. Using the 10:1 probe will help in noise rejection.
If you use the Power Adapter (PM8907), connect a test lead from the black 4-mm banana jack COM (common) to the measurement common (ground) of the system under test. This technique reduces or eliminates any power line related noise.

CHARGING THE BATTERY
WARNING
TO AVOID ELECTRICAL SHOCK, USE ONLY A BATTERY CHARGER THAT IS AUTHORIZED FOR USE WITH SCOPEMETER TEST TOOL.
Use the following procedure to charge the battery pack and power the instrument:
1.Connect the Power Adapter/Battery Charger to line voltage.
2.Insert the Power Adapter/Battery Charger low voltage plug into the Power Adapter connector of the ScopeMeter test tool. The test tool can now be used while the NiCad batteries charge slowly. If the test tool is turned off, the batteries charge more quickly.
NOTE
When the batteries are completely empty, the test tool can not work during charging. In that case it is advised to charge the batteries for 21 hours before using the test tool.
During operation, when the batteries are low, a blinking battery symbol 
appears on the top right of the display. When this occurs there is typically more than 30 minutes of operating time left.
3.The Power Adapter/Battery Charger uses a trickle charge for the batteries, so no damage can occur if you leave it charging for long periods, e.g., through the weekend. Typically a 21-hour recharge provides 4 hours of use.
Saving Battery Life
When operated only on batteries, the test tool conserves power by shutting itself down. If no new keys have been pressed for 6 minutes or if the battery level is too low, the test tool beeps and displays a message. This prompts you to turn off the test tool or to continue. If no key is pressed during the next 5 minutes, the test tool turns itself off automatically.
When the 
is pressed ON, the last configuration prior to the automatic shutdown will be restored.
Automatic power shutdown will not occur if Min Max TrendPlot™ or ScopeRecord™ is active or if any key is pressed. Although recording will continue if the batteries are low, memory retention is not jeopardized.
If the Power Adapter is connected, there is no automatic power shutdown.

LOOKING AT ALL
MEASUREMENT CONNECTIONS
The ScopeMeter test tool provides four signal connection points: two safety BNC jack inputs (red INPUT A and grey INPUT B) and two safety 4-mm banana jack inputs (COM and Ω 
EXT.mV). This arrangement is shown in Figure 1-3. All connections are positioned within a protective recess at the top of the instrument. The banana jacks are also used as Waveform Generator Output. 92B 96B
Figure 1-3. Measurement Connections
In 
mode, you can use the red INPUT A BNC jack and the grey INPUT B BNC jack as input.
In 
mode, only the red INPUT A BNC jack is used as input.
In 
, 
, and 
modes, use the red and black 4-mm banana jacks.
For low frequency measurements (up to about 2 MHz), ground can be connected to the black 4-mm banana jack. For higher frequencies you must use the HF Adapter or Mini Testhook on the probe.
The red 4-mm banana jack also serves as an input connection for an external trigger in Scope mode or as an output connection for the waveform generator. This waveform generator can provide voltage or current output.
Common Ground, Inputs A B
The test tool uses a three-lead connection system for dual input, isolated (electrically floating) measurements.
Input/Output Terminal Ratings
Maximum voltage ratings are defined near the related terminal. Refer to the Specifications in Appendix 10A for complete terminal rating information.

READING THE DISPLAY
The display provides a great deal of information. The major part of the display is always devoted to meter readings or the scope waveform. A Dual display appears in 
, 
, 
, and 
modes, and is divided into two areas: Main display and Bottom display. A Scope display appears in 
mode, and is divided into three areas: Top display, Main display, and Bottom display.
