するようにされていることを特徴とする抵抗計。[Claim for Utility Model Registration] An AC constant current signal for measurement is applied to the resistor to be measured to which a direct current is applied via a test probe, and the current signal for measurement flowing through the resistor to be measured and the current signal are used to In an ohmmeter that determines the resistance value of the resistor to be measured by separating and measuring the AC voltage signal generated in the resistor to be measured from the DC voltage signal via a capacitor, the test probe is brought into contact with and separated from the resistor to be measured. An associated relay is selectively supplied with a drive current, and when the relay is turned on by the supply of the drive current, its contacts open to put the capacitor in a non-short circuit state, and the drive current is cut off. The resistance meter is characterized in that when the resistance meter is turned off, the contacts close to short-circuit the capacitor.
