B-2
Status and Error Messages
Introduction
This Appendix contains a summary of status and error messages, which status register bits
are set when messages occur, and methods to avoid or eliminate most common SCPI errors.
Status and error messages
Table B-1 summarizes status and error messages, which are stored in the Error Queue. Each
message is preceded by a code number. Negative (-) numbers are used for SCPI-de
fi
ned
messages, and positive (+) numbers are used for Keithley-de
fi
ned messages. Note that error
and status conditions will also set speci
fi
c bits in various status registers, as summarized in
Table B-1.
Section 14 has detailed information on registers and queues. Brie
fl
y, you can use the follow-
ing queries to obtain error and status information:
•
:SYST:ERR?
—
reads Error Queue.
•
*ESR?
—
reads Standard Event Status Register.
•
:STAT:OPER?
—
reads Operation Event Register.
•
:STAT:MEAS?
—
reads Measurement Event Register.
•
:STAT:QUES?
—
reads Questionable Event Register.
NOTE
SCPI-confirmed messages are described in volume 2: Command Reference of the
Standard Commands for Programmable Instruments. Refer to the :SYSTem:ERRor?
command.
