The following example sets sequence #2 to do a zero-span calibration every other day
starting at 2:15 PM on September 4, 2008, lasting 15 minutes, without calibration. This
will start ½ hour later each iteration.

CALIBRATE
The programmed STARTING_TIME must be a minimum of 5 minutes later
than the real time clock for setting real time clock (See Section 5.6.4).
Avoid setting two or more sequences at the same time of the day. Any
new sequence that is initiated whether from a timer, the COM ports or the
contact closure inputs will override any sequence that is in progress.
With CALIBRATE turned ON, the state of the internal setup variables
DYN_SPAN and DYN_ZERO is set to ON and the instrument will reset the
slope and offset values for the CO response each time the AutoCal
program runs.
This continuous readjustment of calibration parameters can often mask
subtle fault conditions in the analyzer.
CALIBRATE is enabled, the analyzer's test functions, slope and offset
values be checked frequently to assure high quality and accurate data
from the instrument.
