TESTING DEVICE FOR CURRENT DETECTOR

PROBLEM TO BE SOLVED: To dispense with change of a wiring connection of a test circuit, when a temperature rising of the test circuit is inhibited to avoid a reduction of a measurement accuracy to solve a complex of a work by requiring no adjustment of an output voltage from a power source part through an operator and by reducing a power consumption quantity through shortening a continuous energization time to the test circuit and when it is necessary to convert a polarity of a through-current and a current detector of an object to be tested is changed to a detector having a different standard and characteristics. SOLUTION: A predetermined value of a through-current inputted from a measurement point input device 7 and a measurement value of a through-current measuring device 6 are compared by a comparison/detection device 8. When they agree with each other, an output voltage of an output resistance circuit 9 at this time is measured by an output voltage measuring device 10. Thereby, an output voltage of a current detector 1 relative to a predetermined value of the through-current inputted from the measurement point input device 7 is tested.
