The Outline
AX-126B Battery digital m ohmmeter measures internal resistance of battery having electro motive force. Not affect for thermal electromotive force, can be measured contact resistance such as relay, switch, and connector.
It suitable for internal resistance measurement capacitor, like large capacity capacitor of electric double layer capacitor.
Contact check function is standard equipment: When measure 4 terminals, either one contact failure occurs, outputs Contact Error signal.
