SYSTem:ERRor?
query.
Error queue messages have the following format:
Error queue message
For example, –113,"Undefined header;*T<Err> ST?".
Errors are retrieved in a first- in, first- out (FIFO) order. If more than 30
errors occur, the error queue overflows and the last error in the queue is
replaced with error –350,“Queue overflow”. Any time the queue overflows,
the most recent errors are discarded.
When the errors are read, they are removed from the error queue. This
opens a position at the end of the queue for a new error message, if one
is subsequently detected. When all errors have been read from the queue,
further error queries 0,“No error”.
To delete all the errors in the queue from the front panel:

To delete all the errors in the queue remotely, use:
