摘要
本文所论述的问题,在实际电测量过程中是一个极易被忽视的大问题。由于联接线本身电阻和分布电容的存在,将使应变片的灵敏度降低;输出电压的幅值减小,相位发生改变;影响仪器的调平,以及出现零漂现象。
The paper described herein this article is a big problem very easily neglected in the process of electric test. Because of the existance of the
resistance of the connecting wire itself and the distributed capacitance,
it will make sensitivity of the contingency plate reduce, the range ability
value of the output voltage decrease and the phase change, it will also
affect the instrument adjustment and there will appear the zero drift,
etc. Only by correctly using the connecting wire of the electric test
and holding the revising methods of error, can the electric test be
carried out smoothly and the accuracy of the test result be also
assured.
