Inductor detection methods and experience oled module

1 color code inductor detection
Place the multimeter R × 1 block, red, black pen color code each received either an inductor terminals, then the pointer should be swinging to the right. According to the measured resistance value size, specific identification of the following three conditions: Lcd display module 
A. color code inductor measured resistance value is zero, the internal short circuit fault. B. measured DC resistance of the inductor color code the size of the inductor coil wound enameled wire diameter used, the number of turns wound directly, as long as the resistance value can be measured, the measured color code may be considered a normal inductor The.
(2) the detection of the transformer in the week
A. The multimeter dial to R × 1 block, in accordance with the windings of the transformer in the week pinout law, one by one check each winding off the situation, and then determine whether it is normal. B. Detection insulation
Place the multimeter R × 10k block, do the following test several states:
(A) between the primary winding and the secondary winding resistance value;
(2) the primary winding and the resistance value between the shell;
(3) secondary winding resistance value between the shell.
The results of these tests appear in three ways: lcd graphic display modules 
(1) resistance is infinite: normal;
(2) resistance to zero: a short-circuit fault;
(3) less than infinite resistance, but greater than zero: a leakage fault.
