Calibration Procedures
The CALIBRATE attribute must always be set to OFF for analyzers used in US
EPA controlled applications that have IZS option installed.
Calibration of instruments used in US EPA related applications should only be
performed using external sources of zero air and span gas with an accuracy
traceable to EPA or NIST standards and supplied through the analyzer's sample
The following example sets Sequence2 to carry out a zero-span calibration every other
day starting at 01:00 on September 4, 2002, lasting 15 minutes. This sequence will start
0.5 hours later each day.

Avoid setting two or more sequences at the same time of the day. Any new
sequence which is initiated from a timer, the COM ports, or the contact
closures will override any sequence in progress. Note that two sequences with
different daily increments may eventually overlap.
If at any time an illegal entry is selected, (for example: Delta Days > 366) the
