AT2511直流電阻測試儀(低電流型) @AT2511%
AT2511是一種經(jīng)濟實用型的直流低電阻測試儀，是AT511A的升級版本。
AT2511相對于前代產(chǎn)品AT511A，具有更廣的測試范圍：0.01mΩ～200.0kΩ，大顯示5000數(shù) 。同時提升了測試速度：快可達10次/秒且讀數(shù)穩(wěn)定。改良的全自動量程測試電路，全電子開關(guān)的設(shè)計，可瞬間完成從高量程到低量程的切換。
AT2511使用了0.8寸的高亮數(shù)碼管 顯示，全中文的按鍵和指示器，使儀器顯示更清晰，傻瓜式操作界面也易于使用。
AT2511使用優(yōu)越的小電流測試特性，特別適用于對測試電流敏感的電阻，如鉑熱電阻、銅熱電阻、PTC陶瓷熱電阻、合金絲型直流電阻、電流保護器件的直流電阻等。
AT2511同樣適用于測量各種接觸電阻；變壓器、電感器、電機、偏轉(zhuǎn)線圈繞線電阻；導(dǎo)線電阻；車、船、飛機的金屬鉚接電阻；印制版線條和孔化電阻等。

AT2511 DC resistance tester (low current) @AT2511%
AT2511 is a DC low resistance tester is a economic and practical is an upgraded version of AT511A.
AT2511 compared to the previous generation products AT511A has wider testing range: 0.01M ohm to 200.0k ohm maximum display 5000numbers. At the same time improve the test speed: up to 10 times / secand stable. Improved automatic range test circuit design of the electronic switch can instantly switch from the highest to the lowest scale range.
AT2511 uses bright digital 0.8 inch display the Chinese buttons andindicator the instrument display more clearly fool style operationinterface is easy to use.
The use of small current test characteristics superior to that of AT2511especially suitable for the resistor sensitive to test current such asplatinum thermal resistance thermal resistance heat resistance of PTC ceramics alloy wire type DC resistance current protection device in DC resistance etc..
AT2511 is also used for measuring contact resistance; transformersinductors motor deflection coil winding resistance; resistance of conductor; metal riveting resistance car ship aircraft; printed edition lineand hole resistance etc..
