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 power supply beeps once each time an error is
generated.
If more than 20 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 supply responds with +0,
‘‘No error’’ over the remote interface or ‘‘
NO ERRORS
’’ from the front panel.
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.
Note that the
*RST
(reset command) command does not clear the error queue.
