RuiDeng Riden RD6006 DC power supply
A menu, where you can choose the multiplikator factor. Like 1x (standard), 2x and 5x. When you increase the voltage with the encoder with a faktor 1x in the 2nd digit (1.10V -> 1.20V -> 1.30V.), the raising is very slow, have turn the encoder many times to set the voltage for exampe from 2V to 12V.
