How adjust the current without Load?

 

Questions & Answer

Q 1:The current knob has been turned,why can't the current be adjusted?

A 1:You must connecte a load and the voltage setting cannot be 0, and then the current is adjusted

Q 2:Why isn't the cooling fan working?

A 2:We installed a smart cooling fan with a built-in temperature control sensor that turns on when

                  the temperature reaches 50 degrees Celsius.

 

Q 3:I can't choose the input voltage 220V or 110V?And the EU/AU/US/UK plug ?

A 3:We will send the corresponding products and plug according to your country, if you have

                 special needs, please contact us, we will send the correct products to you.

 

Q 3:Scratches on the screen?

A 3:There is a protective film on the screen that can be peeled off.
