Table 7-9: RS-232 Calibration Messages

Message	Description
START ZERO CALIBRATION	Beginning IZS zero calibration
FINISH ZERO CALIBRATION, SO21=xxxxx PPM	Finished IZS zero calibration
START SPAN CALIBRATION	Beginning IZS span calibration
FINISH SPAN CALIBRATION, SO21=xxxxx PPM	Finished IZS span calibration
START MULTI-POINT CALIBRATION	Beginning multi-point calibration
FINISH MULTI-POINT CALIBRATION	Finished multi-point calibration
1Depends on which units are currently selected.

Whenever the analyzer starts or finishes an Zero/Span calibration, it issues a status report to the RS-232 interface. If the RS-232 interface is in the normal mode, these reports will be sent. Otherwise, they will be discarded. The format of these messages is:

C DDD:HH:MM IIII CALIBRATION STATUS MESSAGE

An example of an actual sequence of calibration status messages is:

C DDD:HH:MM IIII START MULTI-POINT CALIBRATION

C DDD:HH:MM IIII FINISH MULTI-POINT CALIBRATION

There are several methods of both checking the calibration and calibrating the M100AH that are discussed in Section 8. The C command executes a calibration command, which may be one of the following:
