Error Queue
If an error occurs due to invalid input or buffer overflow, its error code
is sent to the error queue. The error code can be read from the
queue with the command FAULT?. The error queue holds 15 error
codes. When it is empty, FAULT? returns 0. The error queue is
cleared when power is reset or when the clear command *CLS is
entered.
