Click to expand... The battery only supplies power to the electronics. It doesn't provide a clock for timing etc. RRITESH said: like ds1307? Click to expand... That's one possibility. There are lots of similar chips. The clock could be part of the measurement chip. too.

Here also this describes just one possibility. Not all meters need to be connected liek, this. There are other ways, too, e.g. wireless communication...
