Multimeter Command Reference
SYSTem
SYSTem
The
SYSTem
command subsystem returns error numbers and their associated
messages from the error queue. You can also query the SCPI version to which
this instrument complies.
Subsystem Syntax
SYSTem
:ERRor?
:VERSion?
:ERRor?
SYSTem:ERRor?
returns the error numbers and corresponding error messages
in the error queue. See Appendix B in this manual for a listing of the error
numbers, messages and descriptions.
Comments
–
When an error is generated by the multimeter, it stores an error number
and corresponding message in the error queue.
–
One error is removed from the error queue each time the
SYSTem:ERRor?
command is executed. The errors are cleared in a first-in, first-out order.
This means that if several errors are waiting in the queue, each
SYSTem:ERRor?
query returns the oldest (not the most recent) error. That
error is then removed from the queue.
–
When the error queue is empty, subsequent
SYSTem:ERRor?
queries
0,“No error”. To clear all errors from the queue, execute the
*CLS
command.
–
The error queue has a maximum capacity of 20 errors. If the queue
overflows, the last error is replaced with -350,“Too many errors”. No
additional errors are accepted by the queue until space becomes available.
