Teledyne 300M instruction manual 5 Control Commands, when the analyzer is in the sample mode

Teledyne API Model 300M CO Analyzer Instruction Manual, 04033, Rev. A

Table 7-5: Control Commands

Command Message	Meaning
"C ZERO<CRLF>"	Do a zero check
"C COMPUTE ZERO<CRLF>"	Calibrate Zero point1
"C SPAN<CRLF>"	Do a span check
"C COMPUTE SPAN<CRLF>"	Calibrate Span point1
"C ASEQ1<CRLF>"	Do a auto-cal sequence2
"C ASEQ2<CRLF>"	Do a auto-cal sequence2
"C ASEQ3<CRLF>"	Do a auto-cal sequence2
"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

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

2 Initiated only If automatic calibration sequence setup is programmed and enabled.

NOTE

The commands in Table 7-5can 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.
