The invention discloses a resistance calibration device, comprising a shell, a shift switch installed on the shell, a connecting terminal connected with each gear of the shift switch, a first connector connected with a common terminal of the shift switch and a second connector connected with the connecting terminal. When the resistance of a measured tooling is calibrated, only the connecting terminal in the resistance calibration device is needed to be connected with the connecting terminal connected with two ends of each resistor fixedly, the first connector and the second connector are respectively connected with a COM end and a V Omega end of a multimeter, the multimeter is adjusted to a resistance testing gear to directly record test data, and then the test accesses of different resistors can be switched on by moving the shift switch, thus resistance value of each resistor needed to be tested can be obtained. Compared with the prior art, through the resistance calibration device disclosed by the invention, the resistance measurement can be realized by only moving the shift switch, while the fact that a probe is needed to be pressed on a pin of a micropositioner when measuring each resistor is avoided, hence the labor intensity of a tooling member is greatly reduced, the testing time is lowered, and the work efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of resistance calibration, and more specifically, to a resistance calibration device. Background technique [0002] Test tooling is a kind of equipment used to test products, including: FCT (Functional Circuit Test, test function) universal base, pneumatic base, general discharge tooling, special discharge tooling, etc. When the test fixture is used for a long time, the resistances in the circuits inside the test fixture are prone to abnormalities (increase, decrease or failure of the resistance value), thus causing the test to be uncontrollable. Therefore, it is necessary to regularly check the resistance value of each circuit in the test tool. [0003] At present, every time the resistance in the test tooling is checked, the tooling worker needs to use the two probes of the multimeter to test the resistance value of the resistance on the pins of the needle holder, and record the data every time a resistan...
