Can anyone tell me what "err" means (other than the obvious!). I get it when either turning on HP3458A or when doing a "test" function from the front panel. The "err" message appears when it finishes doing ROM and RAM tests and when it starts the "Slave test". I have two 3458A's one says "self test failed" when it gives up; the other fails to a "VDC" state.
If it is beyond the user to fix can you tell me where I need to send them to get fixed, please.
Yes you are correct, it means exactly what you think it does, there is an error. Now you need to read the error message by checking it on the front panel so we know what were dealing with. See page 31 of the user's guide for instructions on how to check the error messages then please reply with the messages so we can help you out.
