Error Messages

•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. The multimeter 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, “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 multimeter responds with +0, “No error”.

•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.

•Front-Panel Operation:

3:ERROR (SYS MENU)

If the ERROR annunciator is on, press Shift > (Recall Menu) to read the errors stored in the queue. The errors are listed horizontally on the “parameter” level. All errors are cleared when you go to the “parameter” level and then turn off the menu.

ERR 1: -113

First error in queue

Error code

•Remote Interface Operation:

SYSTem:ERRor? Reads one error from the error queue

Errors have the following format (the error string may contain up to 80 characters):

-113,"Undefined header"
