I am very new to electronics and I am trying to build a solar light for the garden. My question is I borrowed a multimeter from a fried and used for testing leads setting meter to diode connecting positive lead to anode and negative to cathode led lights up. Just received my own multimeter difference is it is auto ranging when I set it to diode and test led positive to anode and negative to cathode it shows OL reverse it it to negative to anode and positive to cathode it shows 0.5, I am somewhat confused it seems non logical. In the multimeter instructions it says diode check resolution 0.001v will supply the forward drop voltage. Operating current wmA Operating circuit voltage 1.48v. Is there someone out there why there is a difference and obviously the led does no light. All other meter functions seem normal.
Any help please Martin.
