Strange Power Supply Behavior
KingSolomon:
Hello-
I recently got a new Siglent bench power supply. However, it has started to have a strange behavior of defaulting to constant current mode when I turn it on. I don't think that this is normal. Is this a common issue with an easy fix? I should also note that I have not put it under any stressful conditions since I bought it.
Thank you!

What model is it?
KingSolomon:
It's a Siglent SPD3303C. https://siglentna.com/power-supplies/spd3303c-series-programmable-dc-power-supply/

Could this be the problem/solution?
