To Set Zoom:
Setting Zoom Offset
You can zoom into one or more of the eight slots in a channel using a combination of
this Zoom Offset and the Zoom Interval. If you decide to zoom in on a portion of the
channel, that is, you zoom in on fewer than the eight slots available, you can use the
Zoom Offset setting to determine which of the slots is displayed first on the left side
of the screen.
Your Zoom Offset setting also determines which slot is displayed when Zoom is set
to Rise/Fall, that is, you choose to display only the rising and falling edges of a
single slot.
The possible values you can set for Zoom Offset depend on your Zoom setting. If
Zoom is set to Slots, that is, you want to display one or more slots or partial slots,
you can set Zoom Offset to any value between 0.25 and 7.75 using 0.25 increments.
If your Zoom setting is Rise/Fall, you can only set Zoom Offset to a whole integer
value between 0 and 7.
Your Zoom Offset setting is also limited by your Zoom Interval setting. With eight
slots in any one channel, your Zoom Offset and your Zoom Interval settings can not
total any more than eight slots. As an example, if your Zoom Interval is already set
to five, you can not set this Zoom Offset any higher than three. Using the same
example, if you want to set your Zoom Offset higher than three, you must first lower
your Zoom Interval setting.
NOTE It is this Zoom Offset setting here that is limited by your Zoom Interval setting. Be
aware that this Zoom Offset setting can be reduced by a later setting of a high Zoom
Interval.
NOTE The first of the eight slots in a channel is always referred to as Slot 0, and the final
slot in the channel is Slot 7.
This setting is only available when View is set to Power versus Time.
