– Errors are retrieved in first-in-first-out (FIFO) order. The first error returned is
the first error that was stored.
– Errors are cleared as you read them. When you have read all the errors from
the error queue, the power indicator turns off and the errors are cleared.
– The error queue is cleared by the clear status (*CLS) command and when
