五 工作原理
Five working principle
根據(jù)歐姆定律,被測電阻R等于施加電壓V除以通過的電流I。即
According to Ohm's law, the measured resistance R is equal to the applied voltage V divided by the current I. That is
V
V
R= ---
- R=
I
I
傳統(tǒng)的儀器的工作原理是測量電壓V固定,通過測量流過被測物體的電流I以標定電阻的刻度來讀出電阻值。從上式可以看出,由于電流I是與電阻成反比,而不是成正比,所以電阻的顯示值是非線性的,即電阻無窮大時,電流為零,即表頭的零位處是∞,其附近的刻度非常密,分辨率很低。整個刻度是非線性的。又由于測量不同的電阻時,其電壓V也會有些變化,所以普通的高阻計的精度是很難提高的。
The working principle of the traditional instrument is the measurement of voltage V fixed, by measuring the current flow through the measured object I to calibrate the scale of the resistance of the resistance value. It can be seen that due to the current I is inversely proportional to the resistance, and not directly proportional to, so the resistance to the display value is nonlinear, the resistance is infinite, the current is zero, namely header zero is infinity, near the scale is very close, the resolution is too low. The whole scale is nonlinear. And since the measurement of different resistance, the voltage V will be some changes, so the accuracy of the common high resistance meter is very difficult to improve the.
ZST-121體積、表面電阻率測定儀是同時測出電阻兩端的電壓V和流過電阻的電流I,通過內部的大規(guī)模集成電路完成電壓除以電流的計算,然后把所得到的結果經過A/D轉換后以數(shù)字顯示出電阻值,即便是電阻兩端的電壓V和流過電阻的電流I是同時變化,其顯示的電阻值不象普通高阻計那樣因被測電壓V的變化或電流I的變化而變,所以, 即使測量電壓、被測量電阻、電源電壓等發(fā)生變化對其結果影響不大,其測量精度很高。從理論上講其誤差可以做到零。而實際誤差可以做到千分之幾或萬分之幾。
ZST-121 volume and surface resistivity tester is measured at the same time at both ends of the resistor are voltage V and flowing through the resistor current I, complete the calculation of the voltage divided by current through the interior of the large-scale integrated circuits, and then the obtained results after a / D conversion to digital shows that the resistance value, namely is resistor voltage V and flowing through the resistor current I is changed at the same time, show the value of resistance is not like an ordinary high resistance meter for measured changes in V voltage or current I change and change, so even if the voltage measurement, the measured resistance, a power supply voltage change has little influence on the outcome, and the measurement accuracy is very high. In theory, the error can be zero. And the actual error can be done a few thousand or ten thousand.
