6-2 AUTOCALIBRATION INTERVAL OPERA-
TION
In the example shown in Figure 6-2, the sys-
tem time is 17:00:00 May 29, 2001.
Therefore, the Zero Cal is set to start at hour
1 with an interval of 24 hours will next occur at
1 AM on the following day.
The Zero & Span Cal is set to start at hour 7
with an interval of 48 hours will next occur at 7
AM on the second day.
The Program Cal is set to start at hour 20 with
an interval of 24 hours will next occur at 8 PM
on the following day.
Start of interval time: is the time of day the
event is to occur in the range of 0 to 23.
Interval time: is the desired interval between
calibrations in the range of 1 to 10,000 hours
(up to 416 + days).
If the start of interval time is prior to the cur-
rent system time, the event will first occur at
the nearest start time plus the interval time.
