Why can''t I test the transistor part of an optocoupler
When testing an NPN BC139 transistor here the test-cycle as described in the url works. The base pin was only used during multimeter testing
Using two multimeters to test the quality of the optocoupler
Home / Using two multimeters to test the quality of the optocoupler
This guide provides a practical, step-by-step method to diagnose a suspect optocoupler. Key Concept: A working opto-coupler and photo-coupler show a clear output change. This detailed guide will walk you through the process of testing an optocoupler using a multimeter, covering various scenarios and providing practical advice to ensure accurate results and avoid common pitfalls. We'll explore the underlying principles, delve into different testing methods, and. Optocoupler is one type of ICs, It isolates input and output section by using optical technology this feature increase safety of circuit.
