I bought 2 Siglent SPD3303C power supplies and one of them has a channel 2 that is not floating( - is tied to chassis ground). I did find one reference to another person that had the same issue and Siglent fixed it since both channels of the supply are supposed to float.
I contacted Siglent and I can return it but seems like I have to pay shipping at least 1 way across the US.
My question is, has anyone else seen this and can I fix it easily myself? Thx for any help.

You could possibly find the wiring flaw or missing insulation bit if you open them up and compare how their ch2 (-) posts are mounted on the front face PCB.
