•
Center (50% of the horizontal full scale)
•
Right (90% of the horizontal full scale)
All events displayed at the left of the trigger point are called pre- trigger
information because they happen before the triggering. All events at the
right of the trigger point, measuring after the trigger point, are called
post- trigger information. The amount of delay range (pre- trigger and
post- trigger information) is available depending on the sweep speed
selected and memory depth.

Turn the vernier scale on by pressing the rotary switch once. You will notice the
indicator is disappeared and now you can move the sweep speed in smaller increments.
