四、體積電阻率測(cè)試儀工作原理
根據(jù)歐姆定律關規定，被測(cè)電阻Rx等于施加電壓V除以通過的電流I發展基礎。傳統(tǒng)的高阻計(jì)的工作原理是測(cè)量電壓V固定，通過測(cè)量流過取樣電阻的電流I來得到電阻值建強保護。從歐姆定律可以看出同期，由于電流I是與電阻成反比，而不是成正比使命責任，所以電阻的顯示值是非線性的效果，即電阻無窮大時(shí)使用，電流為零，即表頭的零位處是∞可持續，其附近的刻度非常密主要抓手，分辨率很低。整個(gè)刻度是非線性的構建。又由于測(cè)量不同的電阻時(shí)創新科技，其電壓V也會(huì)有些變化，所以普通的高阻計(jì)是精度差共創輝煌、分辨率低具有重要意義。
本儀器是同時(shí)測(cè)出電阻兩端的電壓V和流過電阻的電流I，通過內(nèi)部的大規(guī)模集成電路完成電壓除以電流的計(jì)算大部分，然后把所得到的結(jié)果經(jīng)過A/D轉(zhuǎn)換后以數(shù)字顯示出電阻值強大的功能，即便是電阻兩端的電壓V和流過電阻的電流I是同時(shí)變化，其顯示的電阻值不象普通高阻計(jì)那樣因被測(cè)電壓V的變化或電流Ｉ的變化而變解決，所以，即使測(cè)量電壓敢於監督、被測(cè)量電阻幅度、電源電壓等發(fā)生變化對(duì)其結(jié)果影響不大，其測(cè)量精度很高()重要的作用，從理論上講其誤差可以做到零貢獻，而實(shí)際誤差可以做到千分之幾或萬分之幾。

Four. The principle of volume resistivity tester
According to Ohm's law, the measured resistance Rx is equal to the applied voltage V divided by the current I. The traditional high resistance meter works by measuring the voltage V, and by measuring the current I through the sampling resistance, the resistance is obtained. From Ohm's law can be seen as the current I is inversely proportional to the resistance, but not proportional, so is nonlinear resistance display value is infinite resistance when the current is zero, which is zero at the header is infinite, the scale near the very dense, low resolution. The whole scale is nonlinear. Because of the different resistance measurement, the voltage V will change, so the ordinary high resistance meter is of poor precision and low resolution.
This instrument is the current flowing through the resistor V and the voltage across the resistor I measured at the same time, the large scale integrated circuit to complete the calculation of the internal voltage divided by the current, and then the results obtained after A/D conversion by the digital display of the resistance value, even if the current voltage V and the flow resistance of the two ends of the I is changed at the same time, the resistance value is not displayed as ordinary high resistance meter as a result of changes in the measured voltage or current change of V and I, so even if the measurement voltage, the measured resistance and power voltage change has little influence on the results, the measuring accuracy is very high (patent), according to the theory of the error can do zero, while the actual error can be done a few thousandths or very few.
