2. Setting the phase

Repeatedly press the “Sel” button (in the middle of cursor buttons) until the phase
value appears in edit mode (blue background).

The value can be set using numeric keyboard and confirmed by pressing ° softkey. The
value can be set using cursor buttons or rotary knob as well.

Next folders (outputs) are activated by repeatedly pressing „Channel“ softkey.
3. Setting amplitude and phase of harmonic components

First should be selected required harmonic component (1-50). Repeatedly press the
“Sel” button (in the middle of cursor buttons) until the parameter Harmonic appears in
edit mode (blue background).

Number of harmonic component can be set using numeric keyboard and confirmed by
pressing „Enter“ button. The value can be set using cursor buttons or rotary knob as
well. Next to the harmonic component number is displayed amplitude and phase of this
harmonic component.

Pressing the „Sel“ button appears the amplitude of selected harmonic component in
edit mode (blue background). This is not valid for the fundamental harmonic (1.
harmonic component) if harmonics components are deifned as % of RMS. Amplitude
of fundamental harmonic is calculated using the RMS value of output signal and
amplitudes of harmonic components 2-50 in this case.

Amplitude of harmonic components 2-50 can be set using numeric keyboard and
confirmed by pressing „%“ softkey. The value can be set using cursor buttons or rotary
knob as well. Amplitude can be set in range 0 to 30.000%. Amplitude is expressed as
% of RMS value or % of Fundamental harmonic.

Phase of harmonic components 2-50 can be set using numeric keyboard and confirmed
by pressing „°“ softkey. The value can be set using cursor buttons or rotary knob as
well. Phase can be set in range 0.00 to 359.99 °.

„Harm+“ („Harm-“) softkeys facilitate listing among harmonics components. Softkeys
displays amplitude of next (previous) harmonic component.

„Ampl. “ („Phase “) softkeys switch between Amplitude and Phase edit mode for
selected harmonic component.

All harmonic components 2-50 can be cleared by pressing „Clear“ softkey. „Clear“
softkey is available if the fundamental harmonic is displayed.

Output terminals are disconnected if new amplitude is set.
