四、工作原理 

    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。 
    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的变化而变,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。

四、工作原理

Four, work 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 divided by current V by I. The working principle of high resistance meter is the traditional measure voltage V fixed, by measuring the current flows through the sampling resistor I to get the resistance value. From Ohm's law can be seen, the current I is inversely proportional to the resistance, not proportional, so is nonlinear resistive display value, namely the infinite resistance, current is zero, i.e. zero at the header is ∞, graduated in the vicinity of the very tight, very low resolution. The scale is nonlinear. Because the resistance measurement is different, its voltage V there will be some changes, so the high resistance of ordinary 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的变化而变,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 current and voltage V and flow resistance at the same time measuring resistor I, the large scale integrated circuit internal to complete the calculation of voltage divided by current, and then the obtained results after A/D conversion to digital display resistance value, even if is current and voltage of V and flow resistance at both ends of the I is changed at the same time, the displayed value resistance do not like ordinary high resistance meter that due to changes in the measured voltage or current change of V I and change, so, even if the measurement of voltage, resistance, power supply voltage is measured and the change had little effect on the results, the measuring accuracy is very high (patent), theoretically the error can do zero, while the actual error can be done a few thousandths or very few.
