I use 'diode test/continuity test' feature to measure small red LED's forward voltage (maybe it's its input voltage rating) which is around 1.2V. But when I try to measure Yellow LED, Green, Blue or White LEDs then DMM won't response and shows just 1 or 0 ('N/A' maybe). So I need to measure its forward voltage manually. Is this a way to measure LED's or Diodes's forward voltage, posted schematic here?
I think I just get approx value from the method and won't be accurate as its manufacturer mentioned. Also probably I will get very wrong value if I tried to measure Power LEDs in the circuit. For now I just want to measure small LEDs I have around me (used as indicator LEDs).
(Accuracy is not very critical to me here.)
