JBHF電機引接線使用特性：
電線導體的*允許工作溫度應不超過70℃。具有良好的柔軟性及耐熱、耐溶劑性。
Method for judging breaking point of electric wire and cable JBHF電機引接線
數(shù)字萬用表除了可以進行電壓、電流、電阻、電容和晶體管等基本參數(shù)的測量外，還可以通過變通使用，使其功能得到進一步拓展，達到一表多用的目的?，F(xiàn)給出用數(shù)字萬用表判斷電線電纜斷點的方法。
Digital multimeter can in addition to measuring basic parameters of voltage and current, resistor, capacitor and transistor etc., but also through flexible use, its function can be further extended to a table for multiple purposes. A method for judging the breakpoint of the wire and cable is given by the digital universal meter. JBHF電機引接線
當電纜或電纜的內部出現(xiàn)斷線故障時，由于外部絕緣皮的包裹，使斷線的確切位置不易確定。用數(shù)字萬用表可以將這一難題輕松搞定。具體方法：把有斷點的電線（電纜）一端接在220V市電的火線上，另一端懸空。將數(shù)字萬用表拔至AC2V擋，從電線（電纜）的火線接入端開始，用一只手捏住黑表筆的筆尖，另一只手將紅表筆沿導線的絕緣皮慢慢移動，此時顯示屏顯示的電壓值大約為0.445V（DT890D型表所測）左右。當紅表筆移動到某處時，顯示屏顯示的電壓突然下降到0.0幾伏（大約是原來電壓的十分之一），從該位置向前（火線接入端）的大約 15cm處即是電線（電纜）斷點所在。
When the cable or cable in the internal fault, due to the external insulation of the package, so that the exact location of the broken line is not easy to determine. With a digital table can be a difficult problem to get this problem. Concrete method: one end of the wire (cable) with a breakpoint is connected to the wire of the 220V city electricity, and the other end is hung up. The digital multimeter to pull the AC2V block from the wire (cable) FireWire access terminal, with a hand pinch black pen nib, the other hand the insulation red pen along the conductor slowly move, the display shows the voltage value is approximay 0.445V (DT890D scale test) about. When the pen moves to somewhere, voltage display suddenly dropped to 0 volts (about 1/10 of the original voltage), from the forward position (FireWire access terminal) about 15cm is the wire (cable) breakpoint.
