B-2 Error and Status Messages Model 6220/6221 Reference Manual
Introduction
Coded error and status messages are reported for error/status events that may
occur. The coded error and status messages are listed in Ta ble B -1 . Error/status
codes with a negative (-) number are reserved by SCPI. Positive (+) numbered
codes are instrument-dependent.
The code and message is displayed briefly on the Model 622x when the
error/status event occurs. The code and message is also place in the Error
Queue. The following commands are used to read the Error Queue:
SYStem:ERRor?
STATus:QUEue?
When a queue command is sent, the latest error/status event is returned and is
then cleared from the queue. Details on the “Error queue” are provided on
page 11-20.
When an error or status event occurs, a corresponding bit in a status register will
set. The status registers include the Standard Event Register, Measurement
Event Register, Operation Event Register and the Questionable Event Register.
Table B -1 also lists the register bit that is set by the error/status event. The status
structure is covered in Section 11.
NOTE Error/status events +950 through +962 pertain to the KI-220
Language, which is covered in Section 15. The status regis-
ters that are affected by the listed error/status events are ex-
plained in the Model 220, 230 Programming Manual available
for download at www.keithley.com.
