Inductance inductance coil can be generally used to measure by high frequency g table or inductance meter. If do not have the above two meter, DCresistance can be used multimeter measuring coil to judge its quality.

Using a multimeter to measure the size of inductor resistance resistance gear.If the measured resistance of the inductor is zero, then the inductor windingshave internal short-circuit fault; but many of the inductor resistance value is very small, only a few tenths of ohm, preferably with inductance test instrumentto measure; if the measured inductor resistance is infinite, then the inductorwinding or pins on the winding contact place the open circuit fault.

I have the advantage of a creative, passionate, United and progressive team,so we can more flexibly corresponding special needs to appear on the market,tailored to customers, all kinds of coil winding machine. We have abundantengineers can provide good service for customers, we attach great importance to cooperation with industry partners, gambling public house long, provides the most appropriate customer need the goods and solutions.
