Whenever the analyzer starts or finishes a ZS 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. Table 5-20 shows the format of the text of the calibration messages. 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 NOX=xxxxx PPB NO=xxxxx PPB NO2=xxxxx PPB C DDD:HH:MM IIII FINISH MULTI-POINT CALIBRATION
