SYSTem

:ERRor?
:VERSion?
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.
•
When an error is generated by the digitizer, 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 return
+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.
