Volts / Amps / Hertz
This function simultaneously shows the voltage and current signal. 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.
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
impression of the phase shifts.
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.
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.
