
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).
 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.
 The CALIBRATE attribute must always be set to OFF on analyzers with IZS Options
installed and functioning.
 Calibrations should ONLY be performed using external sources of Zero Air and
Span Gas whose accuracy is traceable to EPA standards.
