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 (Setup>Instrument, Section 2.5.9).
•
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.
•
It is recommended that calibrations be performed using
external sources of Zero Air and Span Gas whose
accuracy is traceable to EPA standards.
