四、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，所以普通的高阻計是精度差、分辨率低。 
    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。

6.6測試 
測量時從低檔位逐漸拔往高檔，每撥一次稍停留1～2秒以使觀察顯示數字， 當被測電阻大于儀器測量量程時，電阻表顯示“1"，此時應繼續將儀器撥到量程更高的位置，當測量儀器有顯示值時應停下，當前的數字乘以檔次即是被測電阻值。當有顯示數字時不要再往更高次檔撥，否測儀器會過量程，機內保護電路開始工作，儀器測量準確度會下降。 
6.7 測試完畢將電阻電流量程拔至“104 "檔，電壓量程調至10V后關閉電源
★每測量一次均應將量程開關撥回到104“調零"檔的量程位置以免開機或測量端短路時而損壞儀器。

四、工作原理

Four, work 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。

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.
