Teledyne 200AH 用户手册

 

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 M200AH, 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: 

C LIST 

List calibration commands 

C ZERO 

Enter zero calibration mode 

C SPAN 

Enter span calibration mode 

C COMPUTE ZERO 

Do a zero calibration 

C COMPUTE SPAN 

Do a span calibration 

C EXITZ 

Exit zero calibration 

C EXITS 

Exit span calibration 

C EXIT 

Exit zero or span calibration 

 

When Diagnostic mode is entered from the RS-232 port, the diagnostic mode issues additional 
status messages to indicate which diagnostic test is currently selected. Examples of Diagnostic 
mode messages are: 

D DDD:HH:MM IIII ZERO VALVE=ON 

D DDD:HH:MM IIII ENTER DIAGNOSTIC MODE 

D DDD:HH:MM IIII EXIT DIAGNOSTIC MODE
