Teledyne API Model 200AU NOX Analyzer Instruction Manual, 02293, Rev. F

Whenever a warning message is reported on the analyzer display, if the RS-232 interface is in the normal mode(i.e. not in quiet mode) the warning message is also sent to the RS-232 interface. These messages are helpful when trying to track down a problem with the analyzer and for determining whether or not the DAS reports are actually valid. The warning message format is for example:

W 194:11:03 0200 SAMPLE FLOW WARN

The format of a warning command is W command. Examples of warning commands are:

W

LIST

List all current warnings

W

CLEAR ALL

Clear all current Warnings

Individual warnings may be cleared via the front panel or the command line interface. To clear the sample flow warning shown above the command would be:

W WSAMPFLOW

5.5.5 CALIBRATION Commands and Messages

There are several methods of both checking the calibration and calibrating the M200AU, these are discussed in Section 7. The C command executes one of the calibration commands shown in Table 5-18.

Table 5-18: RS-232 Calibration Commands

Command

Description

C [id] ZERO [1 or 2]

Start remote zero calibration. The number is optional and selects the

 

range to calibrate. If not specified, the range defaults to range 1.

C [id] COMPUTE ZERO

Tells the instrument to compute a new slope and offset. Same as

 

pressing ZERO-ENTR on front panel.

 

 

C [id] SPAN [1 or 2]

Start remote span calibration.

 

 

C [id] COMPUTE SPAN

Tells the instrument to compute a new slope and offset. Same as

 

pressing SPAN -ENTR on front panel.

 

 

C [id] ASEQ number

Executes automatic calibration sequence (1, 2, or 3).

 

 

C [id] EXIT

Exits the current calibration step and goes to the next one.

 

 

C [id] ABORT

Aborts the entire calibration sequence.
