    Description

    Vintage Biddle / Megger Null Balance Earth Resistance Tester
    James G. Biddle Co. - Plymouth Meeting, PA - Made in England
    The Biddle 63220 is a Null Balance Earth Resistance Meter. It measures ground resistance using a hand-cranked oscillator with four resistance ranges adjustable from 0.01 to 9990.00 Ohms.
    The 63220 measures the ground resistance by applying a test current through an earth electrode under test which returns through the soil and a remote terminal.
    The potential between the earth electrode and a remote terminal potential is observed and balanced against an equal potential in the Earth Tester.
    When a null condition is achieved, a read out in ohms is displayed on a meter which, under proper test procedures, is the earth electrode resistance.
