An ohmmeter and circuit therefor which does not require an internal battery or a continuing coupling to an external voltage source during normal use, with the necessary operating electrical power supplied through a high capacity capacitor which, after initial energization by a temporary connection to an external voltage source, develops a stored source of operating power. As the operating current is constant, there is no necessity for scale adjustment prior to each use of the ohmmeter.
