More Information
For more information regarding the Delta (Δ) Amplitude and Flicker Function in Current
mode, refer to "Delta (Δ) Amplitude, Flicker Function (Volts)".
Delta (Δ) Amplitude, Single (Sags & Swells) Function (Volts)
This mode allows the user to output a single or one-time amplitude deviation. From this
mode, the user can specify the RAMP-UP time, the WIDTH of the event, and the %
deviation.
Note
Before starting this section, refer to "Entering the PQ Modes " earlier in
this chapter.
Delta (Δ) Amplitude Mode (Volts)
Press the ΔAMPL softkey to access the Delta (Δ) amplitude functions. From this mode
the flicker and single (sags & swells) functions are accessible. The ΔAMPL Menu, shown
below, appears in the Control Display.

Press the TYPE flicker blue softkey. This will put the calibrator in the single (Sag &
Swells) Mode.
How to Set the Ramp-up Period
Press the RAMP-UP blue softkey. The Control Display changes to a screen, shown
below, instructing the user to enter the period over which the output ramps to the selected
value.

How to Set the Sag & Swell Width
The WIDTH blue softkey allows the user to specify the duration of the sag or swell event
in seconds.
How to Set the Sag/Swell Amplitude
The ΔI/I softkey allows the user to specify the amplitude of the deviation as a percentage
of the nominal output value. The value is positive for swell events and negative for sags.
