Optocoupler Tester 4-Pin Through-Hole & Optocouplers – USB-C Powered Online Detection Tool with LED Indicator, PCB Test Module Repair Technicians(6th)

Product description features:1. Test and confirm that the board under test is in the off state, and the electrolytic capacitors on the mainboard have been fully discharged. It is strictly forbidden to test when the mainboard 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 brightness of the light may be different from that of the optocoupler). As long as it flashes, it means the optocoupler is good)4. Measure to for ensure that the optocoupler test board is in good with the tested optocoupler5. If the indicator light is always on or off, remove the optocoupler from the circuit board, insert it into the optocoupler seat of the breadboard, and reconfirm the test results6.
