三、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。
    本臺電阻率測試儀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。

使用注意事項     
★高阻測量一定要嚴格按使用方法步聚進行,否則有可能造成儀器*損壞或電人。 
7.1 應在“Rx"兩端開路時調零(主機開機)
如接在電阻箱或被測量物體上時調零后測量會產生很大的誤差。一般一次調零后在測試過程中不需再調零,但改變測量電壓后可能要重新調零。 
7.2 禁止將“Rx"兩端短路,以免微電流放大器受大電流沖擊
7.3 在測試過程中不要隨意改動測量電壓, 
★隨意改動測量電壓可能因電壓的過高或電流過大損壞被測試器件或測試儀器,而且有的材料是非線性的,即電壓與電流是不符合歐姆定律,有改變電壓時由于電流不是線性變化,所以測量的電阻也會變化。 
7.4 測量時從低次檔逐漸拔往高次檔 
★每撥一次稍停留1~2秒以便觀察顯示數字,當有顯示值時應停下,記錄當前的數字即是被測電阻值。若顯示“1"時,表示欠量程應往高次檔拔。直到有顯示數字時為止。當有顯示數字時不能再往高次檔撥,否則有可能損壞儀器(機內有過電流保護電路)。除104 Ω檔之外,當顯示低于1.99,表示過量程應換低檔! 
7.5 大部分絕緣材料,特別是防靜電材料的電阻值在加電壓后會有一定變化而引起數字變化 
★由于本儀器的分辯率很高,因而會引起顯示值的末尾幾位數也變化,這不是儀器本身的問題,而是被測量對象的導電機理復雜而使得阻值有些變化。在這種情況下往往取2位有效數就夠了。 
7.6 接通電源后,手指不能觸及高壓線的金屬部分 
★本儀表有二連根線:高壓線(紅)和微電流測試線。在使用時要注意高壓線,開機后人不能觸及高壓線,以免電人或麻手。 
7.7 測試過程中不能觸摸微電流測試端 
★微電流測試端zui怕受到大電流或人體感應電壓及靜電的沖擊。所以在開機后和測試過程中不能與微電流測試端接觸,以免損壞儀表。 
7.8 在測量高阻時,應采用屏蔽盒將被測物體屏蔽. 
★在測量大于1010 Ω以上時,為防止外界干擾面而引起讀數不穩。 
7.9 每次測量完時應將量程開關撥回“104 "檔再進行下次測試
在測量時應逐漸將量程開關撥到高阻檔,測量完時應將電流電阻量程、電壓量程開關撥回低檔。以 確保下次開機時量程開關處在低阻量程檔。

三、工作原理

Three, 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.

本臺電阻率測試儀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。

The resistivity tester 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 at the same time change, resistance displayed value 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 is zero, but the actual error can be done a few thousandths or very few.

使用注意事項

Use the matters needing attention

★高阻測量一定要嚴格按使用方法步聚進行,否則有可能造成儀器*損壞或電人。

★ high resistance measurements using the method must strictly follow the steps, otherwise there may result in permanent damage or power apparatus.

7.1 應在“Rx"兩端開路時調零(主機開機)

7.1 should be in the "Rx" open circuited ends at zero (host computer)

如接在電阻箱或被測量物體上時調零后測量會產生很大的誤差。一般一次調零后在測試過程中不需再調零,但改變測量電壓后可能要重新調零。

If the resistance box or the object being measured at zero measurement will produce great error. A general transfer in the process of testing zero does not need to zero, but change the measurement voltage may want to zero.

7.2 禁止將“Rx"兩端短路,以免微電流放大器受大電流沖擊

7.2 prohibit "Rx" ends of short circuit, so as to avoid the micro current amplifier high current impact

7.3 在測試過程中不要隨意改動測量電壓,

7.3 in the process of testing do not arbitrarily change the voltage measurement,

★隨意改動測量電壓可能因電壓的過高或電流過大損壞被測試器件或測試儀器,而且有的材料是非線性的,即電壓與電流是不符合歐姆定律,有改變電壓時由于電流不是線性變化,所以測量的電阻也會變化。

★ change measuring voltage may be due to the over voltage or current is too large damage to a device or instrument was tested, and some material is nonlinear, namely voltage and current is not accorded with Ohm's law, a voltage change due to current is not a linear change, so the measured resistance will change.

7.4 測量時從低次檔逐漸拔往高次檔

7.4 when measured from low to high grade gradually drawing file

★每撥一次稍停留1~2秒以便觀察顯示數字,當有顯示值時應停下,記錄當前的數字即是被測電阻值。若顯示“1"時,表示欠量程應往高次檔拔。直到有顯示數字時為止。當有顯示數字時不能再往高次檔撥,否則有可能損壞儀器(機內有過電流保護電路)。除104 Ω檔之外,當顯示低于1.99,表示過量程應換低檔!

★ every dial again slightly for 1 ~ 2 seconds in order to observe the display number, when the display value should be stopped, records the current figure was measured resistance values. If the display is "1", said underrange should go to the higher profile drawing. Until the display digital date. When the display numbers cannot go higher gear shifting, or they may damage the instrument (machine over-current protection circuit). In addition to 104 ohm, when the display is less than 1.99, says overrange should downshift!

7.5 大部分絕緣材料,特別是防靜電材料的電阻值在加電壓后會有一定變化而引起數字變化

Most of the 7.5 insulating materials, especially the resistance of antistatic material values in the applied voltage will have some changes caused by digital change

★由于本儀器的分辯率很高,因而會引起顯示值的末尾幾位數也變化,這不是儀器本身的問題,而是被測量對象的導電機理復雜而使得阻值有些變化。在這種情況下往往取2位有效數就夠了。

★ because the instrument resolution is very high, so it will cause the display value of the end digits also change, this is not the instrument itself, the conductive mechanism instead of the measured object is complex and make some changes in resistance. In this case are 2 effective number is enough.

7.6 接通電源后,手指不能觸及高壓線的金屬部分

7.6 after the power is switched on, the metal part of the finger can not touch the high-voltage wire

★本儀表有二連根線:高壓線(紅)和微電流測試線。在使用時要注

★ this instrument has two lines: the roots high-voltage wire (red) and micro current test line. When used to note
