The multifunctional transformer tester includes a housing, and a transformer detection circuit board and a battery are arranged inside the housing, and the battery supplies power to the transformer detection circuit board. A display screen and a multi-function selection switch are arranged on one side of the housing. The display screen is connected with the transformer detection circuit board through the data line, and the display screen can display the output information of the transformer detection circuit board. The multi-function selector switch is connected with the transformer detection circuit board through the data line, and the multi-function selector switch can change the gear position of the transformer detection circuit board. The present invention adds a fixing clip to the original metal probe. When the staff needs to measure accurately, they only need to use the fixing clip to clamp the measured joint to measure accurately, reducing the influence of hand shaking and force on the experimental data. , and the staff does not need to hold the metal probe with both hands to measure, and can debug and record the instrument while measuring.
Description
technical field [0001] The invention relates to a tester, in particular to a multifunctional transformer tester. Background technique [0002] The multi-functional mutual inductance tester is a transformer field test instrument developed by analyzing the mathematical model of the transformer in detail on the basis of the original successful development of the transformer calibrator. The measurement pen of the existing mutual inductance tester is only a single metal probe structure. In the field operation, the staff needs to hold two probes with two hands at the same time for measurement. When the hand shakes or the force is small, it is easy to cause the probe The resistance change between the measured circuit and the measured circuit will affect the accuracy of the measured data. Since the test leads of the mutual inductance tester are made of metal, and there is moisture and dirt in the experimental environment, the test leads of the mutual inductance tester are very easy...
