四、工作原理
Four, working principle

        根據歐姆定律,被測電阻Rx等于施加電壓V除以通過的電流I。傳統的高阻計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,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,所以普通的高阻計是精度差、分辨率低。
According to Ohm's law, the measured resistance Rx is equal to the current voltage divided by the I V. The traditional working principle of high resistance meter is to measure the voltage V fixed, by measuring the current through the sampling resistor I to get the resistance value. 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. And because the measurement of different resistance, the voltage V will also have some change, so the ordinary high resistance meter is the poor accuracy, low resolution.
本儀器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。
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.
