Error Messages
•
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 errors from the queue, the
ERROR annunciator turns off and the errors are cleared. The
instrument beeps once each time an error is generated.
•
If more than 10 errors have occurred, the last error stored in the
queue (the most recent error) is replaced with
-350, “Queue overflow” .
No additional errors are stored until you remove errors from the
queue. If no errors have occurred when you read the error queue, the
instrument responds with +0, “
No error ”.
•
The error queue is cleared by the
*CLS
(clear status) command or
when power is cycled. The errors are also cleared when you read the
queue. The error queue
is not cleared by an instrument reset (
*RST
command) or a card/module reset (
SYSTem:CPON
command).
•
