Less than a year ago, Owon launched this clamp meter very similar to the UT210E. The DMM chip marking has been sanded, but I believe it also uses the DM1106EN like the Owon HDS200 line (which is also sanded). Using your calculator with the backup of my EEPROM (HE24C08) I was able to see that the modification of the order of the resistance/diode/continuity/capacitance functions is successful, but after making this modification the 100A current range becomes unusable, in AC it returns OL and DC returns 60A+ offset to OL. It is also possible to activate the temperature function, which is non-existent in the stock version but the measured value is wrong (expected?). I also tried switching AC/DC modes without success. I assume that these problems are because the Owon CM2100 has 7 positions on the selector (in addition to 2 OFF positions if that is relevant) which perhaps causes the memory addresses to change and also that in the EEPROM there is more useful data than 256 bytes. Any help is welcome, thank you very much! eeprom-cm2100b-original.bin.zip
