四、體積表面電阻測定儀工作原理

   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，即電阻大時，電流為，即表頭的位處是∞，其附近的刻度密，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差、分辨率低。

    According to Ohm's law, the measured ristance Rx is equal to the applied voltage V divided by the current through the I. The traditional high impedance meter works by measuring the voltage V fixed by measuring the current flowing through the sampling ristor I to get the ristance value. As can be seen from Ohm's law, since the current I is inversely proportional to the ristance, rather than proportional to the ristor value displayed is nonlinear, i.e. infinite ristance, the current is zero, that the header is at zero ∞, its the scale is very close to dense, low rolution. Entire scale is nonlinear. Also, because the ristance of different measurement, the voltage V will be some variation, so the ordinary differential impedance meter is the precision, low rolution.

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，其測量很高()，從理論上講其誤差可以做到，而實際誤差可以做到幾或幾。

The instrument is also measure the voltage V across the ristor and a current flowing through the ristor I, large scale integrated circuit via the internal voltage divided by current calculation completion, then the rults obtained after A / D conversion to dial display ristor value, even the voltage V across the ristor and the current I flowing through the ristor is changed simultaneously, which shows the ristance value is not as common as a rult of taking into account the measured impedance chang or voltage V and the variation of the current I, therefore, even if the measuring voltage, ristance is measured, and power supply voltage chang little effect on its rults, the measurement accuracy is high (patent), in theory the error can be zero, the actual errors can be done a few thousandths or very few.
