  • Measurement Of Resistance Or Impedance (AREA)

Abstract

PURPOSE: To make a decision on contact resistance easily by comparing the lightness of a reference light emitting diode or lamp to that of a light emitting diode or lamp connected in series to the contact of a relay to be tested.
CONSTITUTION: To measure resistance at contact (b), push-button switch 2 is turned ON and the lightness of a light emitting diode or lamp 7 showing the value of a current flowing through each contact is compared with those of reference light emitting diodes or lamps 7a, 7b and 7c to judge the contact resistance value of relay 1 to be tested. The reference light emitting diodes or lamps 7a, 7b and 7c are increased or decreased in number according to the percision of the contact resistance value decision.
