"C ASEQ1<CRLF>" Do a auto-cal sequence
2
"C ASEQ2<CRLF>" Do a auto-cal sequence

"C ASEQ3<CRLF>" Do a auto-cal sequence
2
"C ABORT<CRLF>" Aborts auto-cal sequence
"C EXITZ<CRLF>" Exit zero cal only
"C EXITS<CRLF>" Exit span cal only
"C EXIT<CRLF>" Exit zero span or hold

Executed only if the instrument is in the proper calibration mode and concentration is within
calibration limits. This command adjusts slope and offset values.

NOTE
The commands in Table 7-5 can only be entered via the RS-232 port
when the analyzer is in the sample mode.
When a control command is issued, the CPU will respond by issuing a status report. For example
if the host computer issues the command.
C CALZ<CRLF>
to do a zero check, the CPU will send the status report
C DDD:HH:MM IIII START ZERO CALIBRATION<CRLF>
to the RS-232 output.
