五 工作原理
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
V
R= ---
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。
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(nèi)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(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(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。而實際誤差可以做到千分之幾或萬分之幾。
