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 over the remote
interface. 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.
The
*RST
(reset command) command does not clear the error queue.
– Front-panel operation:
Press (Local) key to return to front-panel operation mode if the power
supply is in remote operation mode.
If the ERROR annunciator is on, press key to view the errors. Use the knob
to scroll through the error numbers. Press to view the text of the error
message. Press or key to decrease or increase the scrolling speed of the
text on the display. All errors are cleared when you exit the menu by pressing
the key or let the display time out for about 30 seconds.
– Remote interface operation:
Errors have the following format (the error string may contain up to 80
characters).
3: ERR -102
SYSTem:ERRor? Read and clear one error from the error queue
-102, “Syntax error”
