1.When I power it on, the current displays show zero, is it normal?

If it isn't connected to a load it should read zero because no current is flowing. This DC power supply requires manual current and voltage settings.

2. How do I get it to stay in constant current mode?

CC is attained when the rated set current is exceeded. It would stay in that mode till the current drops back to the preset.

3.How to set the current value without load connecting?

Please short the +/- outputs together, set the current, and remove shorting cable.You could also refer to the operation instruction.

4.Does it remember the last settings when turned off and back on again?

Yes,because it's on a dial.If you don't adjust it and just flip the on and off switch in the front it will remain the same.
