From this menu, the user may edit the wave harmonics. Refer to "Editing Wave
Harmonics" earlier in this section.
Note
Building a wave can be time consuming, especially if using one of the
preinstalled waves. To minimize the time the calibrator has to rebuild the
waveform, leave the calibrator in Standby Mode whenever recalling or
creating waves. Only when
O
is pressed will the calibrator recompute
the waveform.
Φ
& REF Menus
In the Volts and Volts dual output mode, phase between the voltage and current outputs
can be varied by the user. These menus operate in the same fashion as the normal dual
output mode, as described in Chapter 4.

Note
Before starting this section, refer to "Entering the PQ Modes earlier in this
chapter.
Delta (
Δ
) Amplitude Mode (Volts)
Enter the PQ Delta (
Δ
) Amplitude Mode. From this mode, the user can simulate a
continuous change in amplitude of the output (flicker), or a single (one time) change in
output amplitude (sag & swell condition). The
Δ
AMPL mode menu, shown below,
appears in the Control Display.

How to Select the Flicker Function
From the PQ:
Δ
AMPL Menu, select SET
Δ
. The Flicker Menu, shown below appears in
the Control Display.
nn344f.eps
The TYPE blue softkey specifies the function, "flicker" for the flicker function and
"single" for the Sags & Swells function. Ensure that the TYPE is set to flicker.
How to Set the Repeat Frequency
From the Flicker Menu, press the RPTFREQ blue softkey to enter the frequency of the
flicker event. This period is also referred to as the flicker modulation frequency.
How to Set the Modulation Pattern
Press the MODWAVE blue softkey to select either squarewave or sinewave modulation.
