号源としたことを特徴とする抵抗計。[Scope of Claim for Utility Model Registration] An AC signal source that causes a constant AC current for measurement to flow through a resistor to be measured, and a control signal from the AC signal source that generates an AC voltage in the resistor to be measured by the AC constant current. A resistor that has a detector that performs synchronous detection and an A/D converter of an integrator that converts the detected output of the detector into digital, and that determines the resistance value of the resistor to be measured from the conversion data of the A/D converter. The meter is equipped with a frequency divider that divides the clock frequency of the A/D converter to a predetermined value, and the frequency divider is used as an AC signal source that supplies an AC constant current for measurement to the resistor to be measured. A resistance meter featuring
