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, 3- conductor 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.
