220V AC Inductor Switch



Precautions
The resistance should be checked before use. Checking whether the performance is good or not is measuring whether the actual resistance is consistent with the nominal value and whether the error is within the allowable range. The method is to measure with the resistance of the multimeter.

Two points to note when measuring
1, according to the measured resistance value to determine the range, so that the pointer indicates the middle of the scale line, so easy to observe.
2, after determining the resistance file range, it is necessary to carry out zero adjustment, the method is a short-circuit between the two table pens (direct contact), adjust the "zeroing" electrical appliances so that the pointer is accurate on the Ω scale line "0", and then measure the resistance Resistance value. In addition, pay attention not to touch the two ends of the resistor or contact the metal part of the test pen. Otherwise it will cause a test error.
The resistance value measured with a multimeter is close to the nominal value. It can be considered that the quality is basically good, and if there is too much difference or no problem at all, it is bad.
