Working principle
根据欧姆定律，被测电阻Rx等于施加电压V除以通过的电流I。传统的高阻计的工作原理是测量电压V固定，通过测量流过取样电阻的电流I来得到电阻值。从欧姆定律可以看出，由于电流I是与电阻成反比，而不是成正比，所以电阻的显示值是非线性的，即电阻无穷大时，电流为零，即表头的零位处是∞，其附近的刻度非常密，分辨率很低。整个刻度是非线性的。又由于测量不同的电阻时，其电压V也会有些变化，所以普通的高阻计是精度差、分辨率低。
According to Ohm's law， the measured resistance Rx is equal to the applied voltage V divided by the current I. The traditional high resistance meter works is the measurement of the voltage V fixed， by measuring the flow through the sampling resistance of the current 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 since the measurement of different resistance， the voltage V will be some changes， so the average high resistance meter is poor accuracy， low resolution.
本仪器是同时测出电阻两端的电压V和流过电阻的电流I，通过内部的大规模集成电路完成电压除以电流的计算，然后把所得到的结果经过A/D转换后以数字显示出电阻值，即便是电阻两端的电压V和流过电阻的电流I是同时变化，其显示的电阻值不象普通高阻计那样因被测电压V的变化或电流Ｉ的变而变，所以，即使测量电压、被测量电阻、电源电压等发生变化对其结果影响不大，其测量精度很高(**)，从理论上讲其误差可以做到零，而实际误差可以做到千分之几或万分之几。
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 the measured voltage or current change of V I variation， so， even if the measured voltage， the measured resistance and power voltage change has little influence on the results， the measurement accuracy is very high (patent)， theoretically the error can be zero， while the actual error can be done a few thousandths or very few.
