The Outline
Model AX-122N, digital ohmmeter, can be percentage measurement from 0.1Ω to 9.99MΩof resistance value.
The unit is indicated the measurement value for digital displayed by high-speed double integral type analog to digital conversion system, and outputs a signal outside to judge -NG, GO, and +NG installing with comparator.
