(1) Adjust the preset voltage: Press the SET key, Page Down key U-SET, press to manipulate the potentiometer, and then enter the toadjustnumeric value. Press the potentiometer one by one to select the value to be adjusted. Turn the potentiometer to adjust the numerical value. If you want to adjust the voltage to exit, press SET briefly. When adjusting the preset voltage, if the output voltage mode is activated by pressing the on/off button, the output voltage will be refreshed by increasing or decreasing the numerical value; When you press the on/off output voltage mode, the output voltage will not be refreshed by increasing or decreasing numerical values.
(2) Adjust preset current: Press the SET key, Page Down key I-SET, press to manipulate the potentiometer, and then enter the toadjustnumeric value. Press the potentiometer one by one to select the value to be adjusted. Turn the potentiometer to adjust the numerical value. If you want to adjust the current to exit, press SET briefly.
(3) Power down saving: If you want to use the present value including the preset voltage, preset current, and the next brightness check of the LCD module, you should store these values. In normal operation (R-MD), please press the SET button until a red "memo" appears on the LCD screen, then release the button to display that the preset voltage has been stored. You can use the next value.
(4) Extract quick stored values: When the system is set to mode (S-MD) and pressing mode is maintained, the quick stored value can be extracted.
(5) Quick store storage value: Press SET key, Page Down key M-PRE, press the potentiometer, and then enter the storage location of M1 or M2. When it comes to meaning, press shortlym1, and the value will be stored in the location of M1; Press shortlym2, and the value will be stored in M2.If. If you want to exit this mode, press SET briefly
(6) Adjust background brightness: Press the SET key to scroll down to the background brightness. Please play with the potential and enter the adjustment value. Press the potentiometer one by one to select the value to be adjusted. Open the potentiometer to adjust the numerical value to exit the mode. If, short press SET.
