function to get an overview of these values before you analyze the signal in
detail in the other functions.
Scope
Scope shows the voltages, currents and the ϕ (phase) angle in oscilloscope
representation as well as their instantaneous values at the cursor position. With
this function you get a clear picture of current and voltage waveforms and their
distortions.
Harmonics
Every signal can be split into an infinite number of sine waves of different
frequency and amplitude. The contribution of each of these individual sine
waves is represented in a bar chart up to the 50
th
harmonic. The smaller the
harmonics are (starting from the 2
nd
harmonic, the 1
st
is the fundamental) the
better the quality of the power network.
Power
This function indicates the values of the transferred power. At the same time
you can measure active power, reactive power, apparent power, distortion
power and the appropriate power factor. You can also view the active and
reactive power energy.
Note
Demand can be logged by setting the averaging period in the Setup
menu to either 10 or 15 minutes, which produces a record of
consecutive averages. This is called block demand.
Events
Events are voltage dips, swells and interruptions. This measuring mode
automatically records all events for later evaluation. The threshold values for
starting the recording are freely configurable in the menu.
