四,体积表面电阻率测试仪LST-121工作原理
Four, volume surface resistivity tester LST-121 working principle
根据欧姆定律,被测电阻Rx等于施加电压V除以通过的电流I。传统的高阻计的工作原理是测量电压V
According to Ohms law, the measured resistance Rx is equal to the applied voltage V divided by the current I. The working principle of the traditional high resistance meter is to measure the voltage V
固定,通过测量流过取样电阻的电流I来得到电阻值。从欧姆定律可以看出,由于电流I是与电阻成反比,
The resistance value is obtained by measuring the current I flowing through the sampling resistor. As can be seen from Ohms law, the current I is inversely proportional to the resistance,
而不是成正比,所以电阻的显示值是非线性的,即电阻无穷大时,电流为零,即表头的零位处是∞,其
And is not proportional, so the display value of resistance is nonlinear, that is, when the resistance is infinite, the current is zero, that is, the zero position of the meter is the
附近的刻度非常密,分辨率很低。整个刻度是非线性的。又由于测量不同的电阻时,其电压V也会有些变
The scale is very close and the resolution is very low. The whole scale is nonlinear. And because the measurement of different resistance, the voltage V will change
化,所以普通的高阻计是精度差,分辨率低。
So the ordinary high resistance meter is of low precision and low resolution.
本仪器是同时测出电阻两端的电压V和流过电阻的电流I,通过内部的大规模集成电路完成电压除以
This instrument is to measure the resistance of both ends of the voltage V and current through the resistor I, through the internal large-scale integrated circuit to complete the voltage divided by
电流的计算,然后把所得到的结果经过A/D转换后以数字显示出电阻值,即便是电阻两端的电压V和流
The calculated results show that the resistance value is displayed by the V conversion after the A/D conversion
过电阻的电流I是同时变化,其显示的电阻值不象普通高阻计那样因被测电压V的变化或电流Ｉ的变化而
The current I of the over resistance is the same as that of the conventional high resistance meter because of the change of the measured voltage V or the change of the current I
变,所以,即使测量电压,被测量电阻,电源电压等发生变化对其结果影响不大,其测量精度很高(专利),
Therefore, even if the measuring voltage, the measured resistance, the power supply voltage and the like have little influence on the result, the measuring precision is high (patent),
从理论上讲其误差可以做到零,而实际误差可以做到千分之几或万分之几。
In theory, the error can be zero, and the actual error can be a few thousandths of a few.
