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
According to Ohm's law, the measured resistance Rx is equal to the applied voltage V divided by the current I. Traditional high resistance meter working principle is to measure the voltage 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，
The resistance value is obtained by measuring the current I flowing through the sampling resistor. From Ohm's law, it can be seen that the current I is inversely proportional to the resistance,
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
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.
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
The scale is very close and the resolution is very low. The whole scale is nonlinear. And because the measurement of different resistance, the voltage V will be a little change
化，所以普通的高阻計是精度差、分辨率低。
So the common high resistance meter is of low precision and 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
The instrument is to measure the voltage at both ends of the V and the current through the resistance of I, through the internal scale integrated circuit to complete the voltage divided by
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
The calculation of the current, and then the results obtained after the A/D conversion to figure out the value of the resistance, even the resistance of both ends of the voltage V and flow
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
The current I of the over resistance is changed at the same time, the resistance value which is displayed is not the same as that of the ordinary high resistance meter because of the change of the measured voltage V or the change of the current I.
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()，
Change, so, even if the measurement voltage, measured resistance, supply voltage and other changes have little impact on its results, the measurement accuracy is very high (patent),
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。
In theory, the error can be zero, and the actual error can be done a few thousand or ten thousand.
