四、工作原理
根據(jù)歐姆定律,，被測電阻Rx等于施加電壓V除以通過的電流I,。傳統(tǒng)的高阻計(jì)的工作原理是測量電壓V固定，通過測量流過取樣電阻的電流I來得到電阻值,。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。
本儀器是同時(shí)測出電阻兩端的電壓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,，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，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(duì)其結(jié)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(shí)際誤差可以做到千分之幾或萬分之幾。

According to Ohm's law, the resistance being measured Rx is equal to the applied voltage divided by current V by I. The working principle of the high resistance meter is the traditional measuring voltage V fixed, by measuring the current flowing through the sampling resistor I to obtain the resistance value. From Ohm's law can be seen,because the current I is inversely proportional to the resistance, but not proportional, sois nonlinear resistive display value, i.e., infinite resistance, current is zero, i.e. zero at the header is infinite, scale near the very dense, with a low resolution. The scale is nonlinear. Because the resistance measurement of different voltage, the V will also besome changes, so the high resistance of ordinary gauge is poor accuracy, low resolution.
This instrument is the current flowing through the resistor V and a voltage across the resistor I measured at the same time, through the large-scale integrated circuit internalto complete the calculation of voltage divided by current, then put the results obtainedafter A/D conversion to digital display value of resistance, even current voltage V and the flow resistance at both ends of the I is changed at the same time, the resistance ofthe display value is not like an ordinary high resistance meter that due to changes in the voltage to be measured changes in V or I current and change, so, even if themeasurement of voltage, resistance, power supply voltage is measured change has little influence on the results, the measuring accuracy is very high (patent), theoretically the error can do zero, while the actual error can do a few thousandths or very few.
