    Hello. Thanks to everybody who has helped me so far

    I managed to get my hands on a Lab DC Power supply.


    I know this must sound really ignorant but I dont know how to use it and cant find any user manual online

    it seems pretty obvius. I put a cable to the +V and one to the ground. Connected to a simple resistor LED circuit and turn it on. I regulate it to 5V but when I measure the voltage and current, nothing. even negative.
    Also the indicator of current stays in 0

    Any experience with this or other LAB power supply?

    Are you saying you regulate it until the display says it is delivering 5 volts, but nothing is coming out of the jacks?

    That would mean you missed a switch somewhere, it has gone into self-protect because your LED circuit is actually shorted, or it's broken.
