a simple zip tie would have fixed it, just zip tie it to the bundle right next to it and it never get near that sharp edge
That was my thought too - tie it to all that stuff two inches above it, away from the metal.
As far as the wiring goes, putting plastic tubing over the wires isn't the answer, cleaning up the edges is.
There is no excuse for that.
Nope. You could still scissor the wires if you ever took the lid off (or it could even happen on the assembly line...)
Better to move the wires completely away from the metal edges.
My issue with that is dealing with the problem that way is a true band-aid fix. It doesn't address the actual problem; that being the unfinished sheet metal.
A second issue I have with that part of the overall design is the mains leads running along side where screws are used to secure the cover.
A third issue I have with that aspect of the design is the lack of a cable clamp to keep the mains wiring from flapping in the breeze.
The above are what really needs to be done in order to bring that instroment up to what I would consider worthy of it's asking price.
For extra credit; placing the mains wiring in a piece of fire retardant plastic tubing would be nice, but not really necessary, but nice.
The crappy binding posts are a blatant attempt to cut costs and hope nobody will notice.
As for the UI; ;it is obvious that whole UI was borrowed from somewhere else and retrofitted for use on a power supply.
If they let me design it...
No screen saver...
I agree with Dave the unused items on the UI have to go until they are put into use.
A simple color change would suffice for attempting to set the voltage outside of the operating range.
One last issue;
What is the point of having a precision power supply that has adjustable output voltage in one millivolt steps while having one millivolt RMS ripple and noise? This is stupid. How is the resolution meaningful if it is obfuscated by noise??
