Whenever the analyzer starts or finishes a 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 M9110AH, these
are discussed in Section 7. C LIST lists the calibration commands available. The C command
executes a calibration command, which may be one of the following:
