DISPLAY

zvx1: This button can be pressed to vertically zoom in on the waveform displayed.

This is a cyclic zoom with x1, x2, x4 and x8 options, which then returns to

normal.

Hold: This option takes a screen shot of the waveform currently being viewed. The

run button allows returning to the continuous waveform display mode.

Phas: This accesses the phasors graphical display screen. The phasors display

screen only gives the data (F4) option on the bottom menu. Pressing data

will return the user to the screen that displays the variables' real time numeric

values. (See Section 6.1.2.)

Phasors are graphically displayed on this screen. A table of the most representative numeric

values is also displayed on this screen.
