•Check power cable/Input power

•Check power switch [(1)]

•Check fuse at the back of the PS1010

Even if the voltage adjust knob is turned the value does not vary.

•Check whether the Volt LED indicator [(4)] is ON. If not then you are not in the right set up and follow up on how to setting the output voltage guide lines

•Check whether the CC LED indicator [(4)] is ON. If so then the current limiting occurs due to insufficient current limit adjustment or due to excessive current draw.
