I do not know what it means.
Does it display that whatever the function or 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 ?
It could be worth cleaning the input sockets.
Some DMM's also detect blown fuses, have you checked fuses?
Other than that I'd check the function selector switch contacts, dirty contacts can give unexpected behaviour i.e. when the CPU is being told one function but the input path is selecting something different.

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.

Hello,
after much research and experimentation. I managed to discover the origin of the error, it is the corrupted flash.
I changed it and it was OK.
Thank you for your help.

Flash as in microprocessor's firmware or configuration EEPROM?
How did you go about replacing and rewriting necessary data?
