SYSTem:ERRor?

Query the instrument’s error queue. A record of up to 10 errors is stored in the instrument’s error queue. Errors are retrieved in first-in-first-out (FIFO) order. The first error returned is the first error that was stored.

When you have read all errors from the queue, the ERROR annunciator turns off and the errors are cleared. 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.
