Title: Measuring device for contact resistance
Inventor: KATSUBE YASUHIRO
IPC: G01R27/02
Filed: 1979-03-09
Abstract: PURPOSE:To enable to accurately determine a deteriorated state of contacts to be  measured, by controlling the potential difference between the contacts so as not to  exceed a predetermined level even when the contacts are deteriorated to cause an  increase in the contact resistance. CONSTITUTION:A reference resistor Rs and a contact resistor Rx for contacts to be measured are series-connected to a variable power source which consists of a variable voltage source Es or a variable current source Is. A control circuit CN is adapted to receive a potential difference Vx occurring between both ends of the contact resistor Rx, and an output value of the variable power source is varied such that the potential difference Vx has a certain value determined by the contact structure. The value of the contact resistor Rx is calculated such as to satisfy an equation Rx= (Vx/Vs)Rs wherein Vs represents a potential difference occurring between both ends of the reference resistor Rs. This permits preventing a film, which is formed due to the oxidation of conacts, from being broken. Accordingly, the state of deterioration of the contacts can be accurately determined.
