ERROR
hardware errors have been detected. A record of up to 20 errors can be stored in the
power supply's error queue. See chapter 5 "Error Messages", starting on page 123 for
a complete listing of the errors.
• 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 over the remote
interface. When you have read all errors from the queue, the
turns off. The power supply beeps once each time an error is generated.
• If more than 20 errors have occurred when you operate the power supply over the
remote interface, the last error stored in the queue (the most recent error) is replaced
with -350, "Too many errors". No additional errors are stored until you remove
errors from the queue. If no errors have occurred when you read the error queue,
the power supply responds with +0, "No error" over the remote interface or "NO
ERRORS" from the front panel.
• The error queue is cleared when power has been off or after a *CLS (clear status)
command has been executed. The *RST (reset) command does not clear the error
queue.
