thanks for your repply.
Does it display that whatever the function or only on current? yes its only on current.
These meters have dual contacts on some of the input sockets to detect if the leads are correctly plugged for the selected function ? Yes this multimeter detect if the probe test is on the right position.
Some DMM's also detect blown fuses, have you checked fuses? The fuses its OK.
I have clean the contacts but, it's the same.
