7 APPENDIX Error Messages
7.1 Error Messages
When the front-panel ERROR annunciator turns on, and the power supply generates a short beep, one or more command
syntax or hardware errors have been detected. A record of up to 20 errors is stored in the power supply’s memory.
Errors are stored and retrieved in first-in-first-out (FIFO) order. The first error returned is the first error that was stored. When
you have read or cleared all errors from the queue, the ERROR annunciator turns off automatically.
If more than 20 errors have occurred, 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 read or remove errors from the queue. If no errors have occurred when
you read the error queue, the supply responds with + 0, “No error”.
The error queue is cleared after a *CLS (clear status) command has been executed. The *RST (reset) command does not
clear the error queue. All error records will be lost when the power is turned off.
Front-Panel operation:
If the ERROR annunciator is on, press the “Error” key repeatedly to read the errors stored in the queue in sequence. The
error queue is cleared when you read all errors and then the “ERROR” annunciator turns off.
Remote interface operation:
SYSTEM:ERROR? Read one error from the error queue
