IMPORTANT

IMPACT ON READINGS OR DATA

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 COMM 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.
