Error Conditions When the front-panel ERROR annunciator turns on, one or more
command syntax or hardware errors have been detected. A reco rd of up
to 20 errors is stored in the multimeter’s error queue. See chapter 5,
“Error Messages,” for a complete listing of the errors.
•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 th e queue, the ERROR annunciator tur ns off.
The multimeter beeps once each time an error is generated.
•If more than 20 errors have occurr ed, 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 occurre d when you read the error queu e,
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.
•Remote Interface Operation:
