Measuring Functions

The following information provides an overview of each rotary switch position.

This function displays the voltage and current values at the same time, plus the

frequency and the neutral-conductor current. You can also use this measuring

function to get an overview of these values before you analyze the signal in

detail in the other functions.

Scope shows the voltages, currents and the

(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 are sinusoidal voltages with a frequency that corresponds to an

integer multiple of the fundamental (line) frequency.

Every repetitive 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 40

harmonic. The smaller

the harmonics are (starting from the 2

harmonic, the 1st is the fundamental)

the better is the power network quality.

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.
