4.Button Function
1>.Short press any button to turn ON/OFF voltage output.Turn ON means enabled output and display output voltage at the first line and display ‘On’ then display output current at the second line.Turn OFF means disabled and display 00.0 at the first line and display ‘OFF’ at the second line.
2>.Long press any button more than 3 second to adjust output voltage.The first line will flashing.Short press button ‘UP’ to increase output voltage and short press button ‘DOWN’ to decrease output voltage. Each time press the button, the voltage changes by 0.1V.Module support long press to quickly adjust the output voltage. Automatically save the set parameters after 3 seconds.
5.Calibrate Voltage/Current
1>.Calibrate Voltage:Keep press anyone button before power ON and then power ON and release button after 5 second.Automatically enter calibration mode after 5 second.The voltage display will flashing ‘8.8.8′.Short press button ‘UP’ and ‘DOWN’ to adjust and calibration voltage.Enter current calibration mode if keep press anyone button for 2 second.Automatically save parameters and return to the normal display interface if keep press button for 5 second.
2>.Calibrate Current:Enter current calibration mode if keep press anyone button for 2 second after Calibrate Voltage.The current display will flashing.Short press button ‘UP’ and ‘DOWN’ to adjust and calibration current.Automatically save parameters and return to the normal display interface if keep press button for 5 second.
6.Using Steps
1>.Input voltage from USB male socket;
2>.Adjust output voltage by buttons to meet require voltage;
3>.Remove input voltage;
4>.Connect load at output terminal;
5>.Re-connect power ON and enjoy using.
7.Note
1>.Please don’t short output.
2>.Its maximum output power is 3W, which cannot exceed.
3>.It supports over-power protection.It will automatically stop output voltage and the screen will display ‘OPP’ if output power is more than 3W.
