A single impulse event between hot and neutral or neutral and ground can be

displayed as a graph, enabling you to see if the impulse is causing zero

crossings.

An impulse graph is produced using the amplitude, direction and position (in

degrees) of the event. The graphical representation is not intended to show

what the wave form looks like nor does it show the duration of the impulse.

To graph an impulse you must choose an event that contains only one

impulse; it is not possible to graph an event consisting of multiple impulses .

1. With the Site Report window open at the Events tab, double-click the

single-impulse event you want to graph.

(There are two other ways of opening an impulse graph: select the single-

impulse event you want to graph by clicking it, and then, either choose Single

Impulse...from the View menu. or click the View Single Impulse button on

the Toolbar.)

2. To open the dialog box of display options, right-click the mouse with the

pointer in the graph.
