                    體積電阻率表面電阻測(cè)試儀工作原理：
Four, working principle
根據(jù)歐姆定律，被測(cè)電阻Rx等于施加電壓V除以通過(guò)的電流I。傳統(tǒng)的高阻計(jì)的工作原理是測(cè)量電壓V固定，通過(guò)測(cè)量流過(guò)取樣電阻的電流I來(lái)得到電阻值。從歐姆定律可以看出，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(wú)窮大時(shí)，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(gè)刻度是非線性的。又由于測(cè)量不同的電阻時(shí)，其電壓V也會(huì)有些變化，所以普通的高阻計(jì)是精度差、分辨率低。
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 is the measurement of the voltage V fixed, by measuring the flow through the sampling resistance of the current I to get the resistance value. Can be seen from Ohm's law, 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 average high resistance meter is poor accuracy, low resolution.
本儀器是同時(shí)測(cè)出電阻兩端的電壓V和流過(guò)電阻的電流I，通過(guò)內(nèi)部的大規(guī)模集成電路完成電壓除以電流的計(jì)算，然后把所得到的結(jié)果經(jīng)過(guò)A/D轉(zhuǎn)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(guò)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，所以，即使測(cè)量電壓、被測(cè)量電阻、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()，從理論上講其誤差可以做到零，而實(shí)際誤差可以做到千分之幾或萬(wàn)分之幾。
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.
