Features:
1: 5V power supply, two lights indicate, simple to use, safe and does not damage the circuit
2: It is very easy and reliable to use, and even a slight short circuit can be successfully tested.
3: If you don't know the structure of the switch transformer! You can test it randomly! As long as 1 of the groups turns green, it proves that the entire switch transformer is not short-circuited!

Specifications:
Part name: Transformer
Material: abs
Color: white
Size: as shown

How to use
1. When using, connect the mobile phone charger to the 5V power supply and touch the switch transformer pins with two fish clips.
2. If you don't understand the structure of the transformer during the test! You can test the pins at will. During the test, as long as 1 group of green lights turns green, it proves that the entire switch transformer coil is normal and there is no short circuit between the turns! There is no need to test each group!
3. If you know the structure of the switch transformer! Only measure the group with the most coil turns! (ie input, 300V group). Book
The tester can be tested on the road! Make it a habit! After each repair or replacement of parts, a road test should be carried out before turning on the machine to reflect whether the secondary is normal.
! If the tester causes a short circuit, the red light will flash and will not turn green. Do not power on, check the rectifier and capacitor in the output section, and then power on after the tester turns green!
