三、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。
    本台电阻率测试仪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。

使用注意事项     
★高阻测量一定要严格按使用方法步聚进行,否则有可能造成仪器*损坏或电人。 
7.1 应在“Rx"两端开路时调零(主机开机)
如接在电阻箱或被测量物体上时调零后测量会产生很大的误差。一般一次调零后在测试过程中不需再调零,但改变测量电压后可能要重新调零。 
7.2 禁止将“Rx"两端短路,以免微电流放大器受大电流冲击
7.3 在测试过程中不要随意改动测量电压, 
★随意改动测量电压可能因电压的过高或电流过大损坏被测试器件或测试仪器,而且有的材料是非线性的,即电压与电流是不符合欧姆定律,有改变电压时由于电流不是线性变化,所以测量的电阻也会变化。 
7.4 测量时从低次档逐渐拔往高次档 
★每拨一次稍停留1~2秒以便观察显示数字,当有显示值时应停下,记录当前的数字即是被测电阻值。若显示“1"时,表示欠量程应往高次档拔。直到有显示数字时为止。当有显示数字时不能再往高次档拨,否则有可能损坏仪器(机内有过电流保护电路)。除104 Ω档之外,当显示低于1.99,表示过量程应换低档! 
7.5 大部分绝缘材料,特别是防静电材料的电阻值在加电压后会有一定变化而引起数字变化 
★由于本仪器的分辩率很高,因而会引起显示值的末尾几位数也变化,这不是仪器本身的问题,而是被测量对象的导电机理复杂而使得阻值有些变化。在这种情况下往往取2位有效数就够了。 
7.6 接通电源后,手指不能触及高压线的金属部分 
★本仪表有二连根线:高压线(红)和微电流测试线。在使用时要注意高压线,开机后人不能触及高压线,以免电人或麻手。 
7.7 测试过程中不能触摸微电流测试端 
★微电流测试端zui怕受到大电流或人体感应电压及静电的冲击。所以在开机后和测试过程中不能与微电流测试端接触,以免损坏仪表。 
7.8 在测量高阻时,应采用屏蔽盒将被测物体屏蔽. 
★在测量大于1010 Ω以上时,为防止外界干扰面而引起读数不稳。 
7.9 每次测量完时应将量程开关拨回“104 "档再进行下次测试
在测量时应逐渐将量程开关拨到高阻档,测量完时应将电流电阻量程、电压量程开关拨回低档。以 确保下次开机时量程开关处在低阻量程档。

三、工作原理

Three, 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.

本台电阻率测试仪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。

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.

使用注意事项

Use the matters needing attention

★高阻测量一定要严格按使用方法步聚进行,否则有可能造成仪器*损坏或电人。

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

7.1 应在“Rx"两端开路时调零(主机开机)

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

如接在电阻箱或被测量物体上时调零后测量会产生很大的误差。一般一次调零后在测试过程中不需再调零,但改变测量电压后可能要重新调零。

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 禁止将“Rx"两端短路,以免微电流放大器受大电流冲击

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

7.3 在测试过程中不要随意改动测量电压,

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

★随意改动测量电压可能因电压的过高或电流过大损坏被测试器件或测试仪器,而且有的材料是非线性的,即电压与电流是不符合欧姆定律,有改变电压时由于电流不是线性变化,所以测量的电阻也会变化。

★ 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 测量时从低次档逐渐拔往高次档

7.4 when measured from low to high grade gradually drawing file

★每拨一次稍停留1~2秒以便观察显示数字,当有显示值时应停下,记录当前的数字即是被测电阻值。若显示“1"时,表示欠量程应往高次档拔。直到有显示数字时为止。当有显示数字时不能再往高次档拨,否则有可能损坏仪器(机内有过电流保护电路)。除104 Ω档之外,当显示低于1.99,表示过量程应换低档!

★ 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 大部分绝缘材料,特别是防静电材料的电阻值在加电压后会有一定变化而引起数字变化

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

★由于本仪器的分辩率很高,因而会引起显示值的末尾几位数也变化,这不是仪器本身的问题,而是被测量对象的导电机理复杂而使得阻值有些变化。在这种情况下往往取2位有效数就够了。

★ 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 接通电源后,手指不能触及高压线的金属部分

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

★本仪表有二连根线:高压线(红)和微电流测试线。在使用时要注

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