SYSTem Subsystem
SYSTem:ERRor?
This query returns error numbers and messages from the N432A error queue.
When an error is generated by the N432A, it stores an error number and its
corresponding message in the error queue. One error is removed from the error
queue each time this query is sent. The errors are cleared in the first-in first-out
order, where the oldest errors are cleared first. To clear all errors from the error
queue, execute the *CLS command. When the error queue is empty, subsequent
SYSTem:ERRor? queries will return +0,"No error". The error queue has a
maximum capacity of 30 errors.

you remove errors from the queue.
