Optocoupler Tester 4-Pin Optocouplers – USB-C Powered Online Detection Tool with LED Indicator, PCB-Based Test Module Repair & Troubleshooting (6th w/Flashlight & Rechargeable Battery)

Product description Features:1. Test to confirm that the board under test is turned off and the electrolytic capacitors on the motherboard are fully discharged. It is strictly forbidden to test when the motherboard is powered on.2. Confirm the optocoupler PIN1 (the pin with a small dot on the test board also has a corresponding mark 1 pin)3. Connect the optocoupler test board to the USB power cord, and test the optocoupler with the test board probe point. If the light in the optocoupler test board keeps flashing, it means that the optocoupler is good (the light brightness may be different from the optocoupler). As long as it flashes, it means that the optocoupler is good)4. Measure to for ensure that the optocoupler test board has good with the tested optocoupler5. If the indicator light is always on or off, remove the optocoupler from the circuit board and insert it into the optocoupler seat of the breadboard to reconfirm the test results6.
