SYSTem:ERRor?
This order is used to query the error information of the power supply. When the
error LED lights on the front panel, it tells us that there is one or more hardware
or order syntax error happened. There are at most 20 groups of error message.
Send the order once will read one error message from the error queue.
Error messages follow the FIFO (first-in-first-out) principle. The first error
will be returned first. when you read all the error tips information in the error
queue. The ERROR led will turn off. When error occur the buzzer of the
power supply will beep once.
If more than 20 errors occurred, the last one stored in the queue will be
replaced by “-350”,
Meaning "too many mistakes.". If the error
messages in the error message queue are not read out, the error
following will not be saved to the queue. If there is no error message,
when read error information, it will return “+0”, meaning “no error”.
If turn off the power supply or send *CLS (clear status) order, the error
messages in the error queue will be cleared. *RST order will not clear the
error messages in the error queue.
