Problems solved by technology

[0003] The application number 200510049572.X pointed out the method to solve this problem, that is, to combine the coils with 1, 2, 3, and 4 units of indication value, but ignore the influence of mutual inductance between the four coils, when each coil indication value After the measurement, the indication value will be different when put together, so the four coils should be placed together in the wooden box and then corrected. When the inductance value exceeds 100mH, due to the large mutual inductance between the separated coils, this method cannot be used.

Embodiment Construction

[0012] in figure 1 and figure 2 Among them, 1 unit indicating coil 9, 2 unit indicating coil 10, 3 unit indicating coil 11, 4 unit indicating coil 12,

[0013] press image 3 Place them, wind them in the same clockwise rotation direction and connect them, and then connect a normally closed contact wire to the five-pole, eleven-throw switch 7 on the connection point. After the four coils are firmly fixed in the wooden box 3, all The wires connected to the switch 7 are led out from the holes of the wooden board 4 which is slightly smaller than the horizontal section of the wooden box, and then the four coils are pressed tightly and fixed with pins 8. Two binding posts 1 and a five-pole, eleven-throw switch 7 are fixed on the panel 6.

[0014] in image 3 The terminal 1 is connected to a unit indicating coil 9 and the start end is connected to the first layer normally closed contact of the five-pole, eleven-throw switch 7. The connecting point of 1 unit indicating coil and 2 unit i...

Abstract

The high frequency inductance decade box can output eleven indication values of (0 - 10). The original decimal induction box winded around signal framework into separate taps is modified into the coils of indicating value 1, indicating value 2, indicating value 3 and indicting value 4. Through diverter switch, eleven indicating values of (0 - 10) can be outputted.

Description

Technical field [0001] The invention relates to an instrument capable of outputting eleven step inductance values ​​from 0 to 10. Background technique [0002] At present, the commercially available decimal inductance box GX9 / 0 is a coaxial inductance coil. When the value is 1 to 4, the frequency characteristic can still be displayed when the value is 5 to 10. Due to the distributed capacitance, the frequency characteristic is poor. [0003] The application number 200510049572.X pointed out the method to solve this problem, that is, divide the coils of 1, 2, 3, 4 into four unit indications, but ignore the mutual inductance between the four coils. When each coil shows the value After the calibration, the displayed value is different when put together. Therefore, the four coils must be put together in a wooden box and then corrected. When the inductance exceeds 100mH, this method cannot be used due to the large mutual inductance between the coils after separation. Summary of the i...
