Unpacking

The following items are included in your Fluke 43B kit. See Figure 1.

Safety Information

Read First
Read the safety information before using the Fluke 43B.
Specific warning and caution statements, where they apply, will be found throughout the manual.

A "Warning" identifies conditions and actions that pose hazard(s) to the user.

A "Caution" identifies conditions and actions that may damage the Fluke 43B.

The following international symbols are used on the Fluke 43B and in this manual:

	Read the safety information in the manual		Double Insulation (Protection Class)
	Earth		Equipotential inputs, connected internally

To avoid electrical shock, use only a Fluke power supply, Model PM8907 (Power Adapter/Battery Charger).

Do the following to avoid electrical shock or fire if a Fluke 43B common input is connected to more than 42 V peak (30 V rms):

• Use only test leads and test lead adapters supplied with the Fluke 43B (or safety-designed equivalents as specified in the accessory list, see Users Manual.)
• Do not use conventional exposed metal banana plug connectors.
• Use only one common connection to the Fluke 43B.
• Remove all test leads that are not in use.
• The maximum allowable input voltage is 600V. Use test lead adapters that have a rating of 600V or more.
• When powering the Fluke 43B, first connect the power adapter to the outlet before connecting it to the Fluke 43B.
• Do not insert metal objects into the power adapter connector of the Fluke 43B.

In the scope function it is possible to select AC coupling and to operate time base ranges and amplitude manually. In this case, 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 42 V peak (30 V rms) not being detected. To guarantee user safety, all signals should first be measured with DC coupling. This ensures that the full signal is measured.

The terms 'Isolated' or 'Electrically floating' are used in this manual to indicate a measurement in which the Fluke 43B 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 Fluke 43B COM (common) is connected to an earth ground potential.
The Fluke 43B common inputs (red INPUT 1 shield, gray INPUT 2 shield, and black 4-mm banana COM input) are connected internally via self-recovering fault protection. This is denoted by the symbol.

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.

If Safety-Precautions are Impaired
Using the Fluke 43B in a manner not specified may impair the protection provided by the equipment. Before using, inspect the test leads for mechanical damage and replace damaged test leads!
If it is likely that safety has been impaired, turn the Fluke 43B off and disconnect it from the line power. The matter should then be referred to qualified personnel. Safety is likely to be impaired if, for example, the Fluke 43B fails to perform the intended measurements or shows visible damage.

Current Probe

• Use extreme caution when clamping the current probe around uninsulated conductors or bus bars.
• Never use the current probe on circuits rated higher than 600V in measurement category III (CAT III) of EN/IEC61010-1
• Keep your fingers behind the finger guard.

Do not use a probe that is cracked, damaged, or has a defective cable. Such probes should be made inoperative by taping the clamp shut to prevent operation.

Introducing the Product

Powering the Device

To power the Fluke 43B from a standard AC outlet, perform steps 1-3.

1. Plug the power adapter into the AC outlet.
2. Connect the power adapter cable to the Fluke 43B (see Figure 2).
   
3. Turn the Fluke 43B on.
   The opening screen will appear on the display (see Figure 3).
   

Note
If the Fluke 43B does not turn on, the batteries may be dead. Leave the Fluke 43B connected to the outlet for 15 minutes and try again.

The screen shows which test leads or probes you should use on the inputs.
Note that in the screen shown in Figure 3, for example, you should use TEST LEADS for voltage measurements and a 1 mV/A current probe for current measurements.

Inputs

INPUT 1: Use the red test lead on input 1 ( )
COM : Use the black test lead on the COM input ( COM).
Use these inputs for all voltage measurements, and for Ohm, continuity, diode capacitance and temperature measurements.
The Fluke 43B common inputs (red INPUT 1 shield, gray INPUT 2 shield, and black COM input) are connected internally via self-recovering fault protection.
INPUT 2: Use the i400s AC current probe on input 2 ( ).
This input is mainly used for current measurements. Use the BB120 banana-to-BNC adapter to connect the current probe.

Note
If you use other test leads or probes, change the probe settings in the instrument setup menu (see "Selecting Probes").

Main Menu

All functions can be easily selected from the main menu.

1. Open the main menu

Volts / Amps / Hertz

This function simultaneously shows the voltage and current signal. Also the Crest factor is shown. Use this function to get a first impression of the voltage and current signal before examining the signal in more detail with the other functions.
With the ENTER key you can toggle between Volts / Amps / Hertz, Power, and Harmonics functions.

Power

This function measures and displays the following power readings: active power (W), apparent power (VA), reactive power (VAR), power factor (PF), displacement power factor (DPF or cos ϕ) and frequency. The voltage and current waveforms give a visual representation of the phase shifts
Fluke 43B can perform power measurements on balanced 3-phase, 3conductor power systems. The load must be well balanced and have either a wye or delta configuration. This makes it possible to measure 3 phase power using single phase connections. The 3 phase power mode measures the fundamental power only.
With the ENTER key you can toggle between Power, Harmonics, and Volts / Amps / Hertz functions.

Harmonics

Harmonics are periodic distortions of the voltage, current, or power sine wave. The signal can be conceived of as a combination of various sine waves with different frequencies. The contribution of each of these components to the full signal is shown as a bar.
The large numbers refer to the full signal; the small numbers belong to the selected harmonic component.
With the ENTER key you can toggle between Harmonics, Volts / Amps / Hertz, and Power functions.

Sags & Swells

Sags and swells measures fast deviations (from one cycle to a few seconds) from the normal voltage signal, and displays current simultaneously.
The results are plotted on the screen as a graph. The graph shows the minimum and maximum values at each point of the graph.
The SAGS & SWELLS function is particularly useful to record flicker.

Transients

Transients are fast spikes on the voltage (or current) signal. Spikes may contain enough energy to damage sensitive electronic equipment.
This function detects spikes on the voltage signal and stores a picture of the signal in memory. A transient is detected when it crosses an envelope around the voltage waveform. The width of the envelope can be set manually.

Inrush Current

Inrush currents are surge currents which occur, for example, when a large motor is started.
This function shows the current signal at the moment of the surge. If the current exceeds a specified level, the signal appears as a gray band on the display formed by the peak-peak values of the waveshape.
Use INRUSH CURRENT to look for inrush currents or other surge currents.
Measure the peak current and duration of the surge current.

Selecting Probes

For standard operation, use the red test lead on input , the black test lead on COM and the current clamp on input . If you are using other test leads or probes, you must change the probe settings accordingly.

1. Open the main menu

Select the type of probe you are going to use on input 1. For all applications in the Applications Guide, you must use test leads.

4. 
   
5. Accept the probe settings for input 1. The screen closes.
6. Select PROBES again.

Select the sensitivity of the current probe you are going to use on input 2.
For all applications in the Applications Guide, use the i400s current probe and choose 1 mV/A.

7. Move to the probe settings for input 2.
   
9. Accept the probe settings for input 2.

Note
Select 1V/A when using testleads on input [2] in the Scope Mode. A reading of 1A then equals 1V.
