Hello, I'm very new to electronics and recently got a bench power supply (an Eventek kps305d) for a metal etching project. It worked great for the first few tests, but now I've run into a problem: when I hook up my positive and negative wires and turn on the bench power supply, it will only go up to around 3 volts. At first I thought maybe I blew a fuse or something, but when checking the power supply with a multimeter it performs very well, easily going up to 30 volts.
Any ideas as to where I can start troubleshooting my problem?
Many thanks!
