1) all symbols as selected measurement (Ohm, mA, A, V...) but no 7 segment digits (blank)
2) see 1
3) see 1
4) nothing, still blank, beeper does also not work
5) see 4
6) see 4
But if you select MIN/MAX, you read 00.00, so the digits themself and the µC are not the problem...
Thx a lot for your patience but as I have "some more DMMs" its not important to reactivate that one, anyway its an TrueRMS which would have been missing in my equipment...
