Hello. Thanks to everybody who has helped me so far
I managed to get my hands on a Lab DC Power supply.
**broken link removed**
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?
Your output will be between the (+) and (-) terminals and not the Ground terminal. Also looking at it it looks to have current limiting so if it works like I think it works you will need to have the current pot turned up slightly to see any output. I would turn the fine current adjust up and then see what you get if you turn the voltage adjust up. Remember the (+) and (-) terminals and not the Ground terminal. Ground is chassis ground and not part of your DC output.
Not going to work with the supply you have. You have a single ended supply. That is just 2 terminals. The Ground terminal is just that, a chassis ground. What you want could only be done with two of what you have connected in series with the center point being common. If you want +12 0 -12 you need a dual supply which you do not have.
