Home / How to measure an optocoupler A7840 with a multimeter
The optocoupler (PC-817) has four pins, pins 1-2 are internally connected to an LED and pins 3-4 are connected to a NPN transistor. Take an analog multimeter, set it to the RX1 or RX10
Testing an optocoupler IC with a multimeter involves a two-step process: first, verifying the functionality of the LED using the diode test mode, and second, checking the phototransistor''s
