WARNING!
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 port (refer to Section 8.2).
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.
