Error Reporting Commands
EC?
Description : RS232_ERR Byte Query
Echo: RS232_ERR Byte.
Query the value of the RS232_ERR byte. The value of the RS232_ERR byte is
sent to the computer in ASCII format and with a <LF><CR> terminator.
RS232_ERR and bit 0 of STATUS are then cleared to provide a clean error
reporting slate.
Important: See ““Troubleshooting the RGA Communications”” in the RGA
Programming chapter for more details on the use of this query.
Parameters: This command is a query, and can only have one parameter format:
EC?
Error checking:
The only acceptable parameter is a question mark.
The absence of a parameter (i. e. EC) is treated as a bad-parameter error.
ED?
Description : DET_ERR Byte Query
Echo: DET_ERR Byte.
Query the value of DET_ERR and update its value after running a fresh check on
the Electrometer (Bit5 of STATUS and the DET_ERR byte are updated based on
the tests results). The DET_ERR byte value is returned to the computer in ASCII
format and with a <LF><CR> terminator. No errors are present as long as the
byte value is zero.
Consult the Error Byte Definitions section in this chapter for detatils on the
different error bytes of the RGA.
Consult the RGA Troubleshooting chapter of this manual for possible causes and
solutions to any problems reported.
Always try the query a second time before declaring a hardware problem.
Important : The electrometer is not affected by this test, and the detector is
restored to its pre-test configuration once the command excecution is over.
Parameters: This command is a query, and can only have one parameter format:
ED?
