Q: can I connect either Power supply DC connection to Ground?

Mikebeeny Yes, the outputs are floating, I use 2 power supplies in series to get a positive & negative output. I have removed the power supply earth to mains on the power in however to remove ground loops when testing amplifiers.

Mikebeeny Sadlyno, it does not control voltage, it lowers the speed by changing the time of pulses. The only way is a transformer. 190 volts is an odd voltage?? I would personally not use this device for anything. It is very dangerous. I good product to get electrocuted buy.

Mikebeeny You will need to zero the meter, probably on most clamp measurements. This is quite common. After you turn it on , it will have a random number on the display. Simply press the red button marked Z stoke F a couple of seconds till it bleeps and reads zero.
