一、產(chǎn)品概述：該儀器是用于測量電池內(nèi)部阻抗及電壓，它是對被測對象施加1KHz交流信號，通過測量其交流壓降而獲得其內(nèi)阻（它不同于多用表測量電阻的原理，它所測量的值上毫歐級，而多用表測量的是歐姆級，且多用表只能測量無電源對象的阻值，而內(nèi)阻儀不僅可測無源對象的阻值，也可測有源對象的阻值），它通過測定內(nèi)阻來判斷電池的優(yōu)劣。不僅測試速度快且可靠性高。它的最大優(yōu)點是能夠設定測試參數(shù)的范圍，實測結果不在設置范圍之內(nèi)，微電腦系統(tǒng)可以自動報警。杜絕人為誤判誤讀的錯誤，保證產(chǎn)品質量。這也是與普通內(nèi)阻儀的區(qū)別所在。二、適用范圍：1、移動電話使用的鎳鎘、金屬氫化物電池（組）鋰電池。2、鉛酸蓄電池和免維護蓄電池。3、也可適用各類電池研究試驗的科研單位和生產(chǎn)廠家。三、產(chǎn)品特點：1，智能報警系統(tǒng)：與普通內(nèi)阻測試儀相比，此種測試儀帶有智能報警系統(tǒng)，電池的電壓、內(nèi)阻范圍可進行設置，測量結果超過設置的范圍，微電腦系統(tǒng)可自動報警。2，程序智能：此儀器內(nèi)部帶微電腦系統(tǒng)，單片機控制，采用智能化程序。3，操作簡便：配送快速測試架，安裝銅條，方便操作。4，選材嚴格：所有選材都是進口組件，采用原裝進口2543IC集成管，運算速度快，可靠性高。5，測試精度高： 電壓分辨率：0.01V 內(nèi)阻分辨率：2?：1m? 200m?：0.1m?6，測試速度快：能在瞬間顯示測試結果。四、綜合指標：1、輸入電壓：AC220V 10% 50Hz 2Hz2、溫度：0 50℃3、外形尺寸：300 250 100（㎜）4、重量：1.5㎏5、保險管：0.5A250V快熔式保險管6、顯示器：數(shù)字式五、測量范圍及精度：測量項目量程測量范圍分辯率測定時間精度輸入阻抗電阻200 m 0.1-200 m 0.1 m 100ms 0.5 m 2 1 m -2 1 m 100ms 2 m 電壓19.99V0-19.99V0.01V100ms 0.01 V10K JX-008 Automatic battery inner resistance testing machine ,which is shortenedly termed as machine hereafter, is applied to measure the inner resistance of battery and the damage degree of acidification membrane done to the battery. By imposing 1KHz AC signal on the object tested, the inner resistance can be worked out through measuring its AC voltage drop. (It is different from the principle of measuring resistance with multi-purpose electric meter. It is utilized to measure milliohm-class resistance and can be applied for object with or without power supply, multi-purpose electric meter is used to measure ohm-class resistance and only applied for object with no power supply; so the two cannot be thought as equal.) The quality of battery is measured by magnitude of the resistance value. Generally speaking, the smaller the resistance value is, the better quality the battery has. Therefore, it is quick and reliable to test the quality of battery by measuring the inner resistance. II. Applicable Scope 1. Cadmium nickel battery, metallic hydride nickel battery and lithium battery for mobile phone; 2. Lead acid storage battery and maintenance-free storage battery; 3. Scientific research units researching various batteries or battery producer. III. Guide line for work safety In order to prevent the battery and machine from being damaged, the rules hereafter should be followed. 1.Check before using to ensure that there is no breakage on the surface of the machine and no shortage of fittings. Pay attention to the insulativity of elements near the connector. 2.Check the testing needle,chang it if the testing needle is broken off or damaged somewhere. 3.The testing needle in the same board cannot be connected in case of short circuit. 4.The machine is prohibited to be used near volatile gas,steam,dust and acid environment. 5.The inner resistance and voltage shoud be within the measuring scope of the machine, or the reading will be inaccurate, even the machine might be ruined when the voltage is obove 40.00V . 6.Ensure the normal working of the machine by measuring the known resistance. Chech out the machine according to the methods defined by this specifications if it is out of order.(Chapter 10, troubleshooting). Please sent it back to factory for repair if the problem is not solved. 7.If the fuse is ruined, cut off the power source and replace it with the fuse of the same size. 8.Cut off the power source before inserting terminal stub into the machine port. 9.Machine is prohibited to be used for measuring high voltage power source(e.g, power source with 220V or a higher voltage.),or you should be responsible for the concequance caused.
