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.
