5.3.2.2.1. Key F4 “Fnz” in AC+DC voltage measurement
While measuring AC+DC voltage, press key F4 (Fnz) to open
the drop-down menu shown on the screen to the side. At each
subsequent pressure of key F4, the cursor will scroll through the
available items, as follows:
• Max: it constantly displays the maximum RMS value of
Voltage;
• Min: it constantly displays the minimum RMS value of
Voltage;

• Cr+: it constantly displays the maximum positive crest value;
• Cr-: it constantly displays the minimum negative crest value;
• Rst: it deletes all stored Max, Min, Cr+ and Cr- values;
• Esc : it goes back to a normal measuring mode.
By pressing key F3 (OK), the selected item is confirmed.
To the side, an example of measurement with active Max
function. The display shows the active function.

5.3.2.3. Voltage harmonics
The screen shows an example of Voltage Harmonics
measurement.
By pressing keys F1 (◄) or F3 (►), it is possible to move the
cursor over the graph and to select the harmonic to be
measured.
It is possible to measure up to the 25 th harmonic, for
fundamental frequencies between 10Hz and 75Hz, and up to the
8
th harmonic for fundamental frequencies between 75Hz and
400Hz.

open the drop-down menu shown on the screen to the side. At
each subsequent pressure of key F4, the cursor will scroll
through the available items, as follows:
• Max: it constantly displays the maximum RMS value of the
selected current harmonic;
• Min: it constantly displays the minimum RMS value of the
selected current harmonic;
• Abs: it displays the absolute value of the harmonics in Volts;
