Current Inrush Example

This example illustrates programming the SW to simulate a current inrush waveform
that is 0V between 0° and 90°, then instantaneously jumps from 0V to 120V at 90°.

At the MAIN MENU, use either the Knob or the Up/Down Arrow keys to select the

WAVEFORM

menu, then either press the

Enter

key or the

Right Arrow

key.

The WAVEFORM Menu will default to the LOAD sub-menu. If the cursor is not
pointing to LOAD, use the Knob or Up/Down Arrow keys to select

LOAD

3. Press

the

Enter

key to enter the

FUNC

(function) mode.

4. Press

Enter

> again to place a box around the waveshape selection.

Use the Knob to cycle through the waveshape selections until

SINE

appears in

the FUNC box.
