A zero value is returned when the error queue is empty. To read the entire contents of the
error queue, repeat ERR? until the response 0,“No Error” is returned. For terminal users,
the error queue return for ERR? is always 0,“No Error” because error messages are
returned instead of queued.
Response: <value>, (error code value)
<string> (text string explaining the error)
Example: ERR? returns 0,“No Error”
Return 0,“No Error” when the error queue is empty.
