6-62 Error Reporting Commands
SRS Residual Gas Analyzer
Always try the query a second time before declaring a hardware problem.
Parameters: This command is a query, and can only have one parameter format:
EQ?
Error checking:
The only acceptable parameter is a question mark.
The absence of a parameter (i. e. EQ) is treated as a bad-parameter error.
ER?
Description : STATUS Byte Query.
Echo: STATUS Byte.
Query the value of the STATUS Error byte.
The STATUS byte value is returned to the computer in ASCII format and with a
<LF> terminator. No errors are present as long as the byte value is zero.
If one or more bits of the STATUS byte are found set, the specific error bytes
(PS_ERR, DET_ERR, QMF_ERR, CEM_ERR, FIL_ERR, and RS232_ERR)
must be queried individually to diagnose the problem.
Consult the Error Byte Definitions section of 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.
Important : Since internal checks are constantly being performed within the
RGA Head, the STATUS Byte should be queried regularly by the programming
software to detect any possible problems.
Parameters: This command is a query, and can only have one parameter format:
ER?
Error checking:
The only acceptable parameter is a question mark.
The absence of a parameter (i. e. ER) is treated as a bad-parameter error.
