The Outline
Model AX-1142N, digital ohmmeter, can easily measure every resistance from 0.00mΩ to 15.000MΩ, it also possible to percentage measurement for the setup standard value.
Built -in comparator, it can be informed the judgment result by LED indication for LO, GO, HI, and buzzer, also can be printed out.
