As shown in Fig. 2, “div” value within standard is displayed on PC screen.

As shown in Fig. 3, it becomes easy to judge if the standard range of cycle of waveform is set by cursor.

The standard value, TIME/DIV, and CURSOR(T1,T2) varies according to the conditions of low-speed adjust-

ment, high-speed adjustment, and other lenses, etc, so check by Fig. 2 of the PC screen when adjustment is 

made.
