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.
