The spacing of the binding posts would be irritating, but their sloppiness is a fail. For a 1mV accuracy, it seems kinda dumb to not have sense wires. I have mixed feelings about multi-purpose knobs - but I will reserve any criticism until after having tried it out (which isn't likely)
I did empathise with Dave when he reached the maximum voltage and this stupid window pops up on the screen. EXTREMELY annoying and totally unnecessary. One would assume that anyone using a lab supply would understand its limitations and work out very quickly that the maximum has been reached by the display no going any higher. If they couldn't, then I'd be anxious about them being anywhere near the gear. If Siglent
really want to throw up a notification, then do it with a little indicator that flashes up somewhere NOT over the active information areas of the screen - and even then, only when the knob is turned to the right plus, maybe half a second. It mustn't impede operation in any way.
Q. Dave: When this window pops up -
1. Does it lock out any adjustment until it closes? (if so, it could find itself flying out the window real quick)
2. If not, does adjusting the voltage down cause the window to disappear immediately?
As for the metalwork...
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.
Absolutely. Just get rid of the knife.
