4. Button/Potentiometer/LED introduction:
1>.Long press means need keep press for more than 3seconds.
2>.Left Button: Long press is used to set default ON or OFF for next re-power at
display mode or as ‘Minus -’ in calibration mode. Short press to select whether
output voltage at display mode.
3>.Right Button: Long press is used to enter or exit calibration setup mode at
display mode or as ‘Plus +’ in calibration mode.Short press to switch display
output voltage,output current, output power or display these parameters in
turn.
4>.CV Potentiometer: Adjust output voltage.Increase the output voltage when
rotating clockwise. Please rotate the CV potentiometer 10 turns in
counterclockwise if the output voltage cannot be adjusted.
5>.CC Potentiometer: Adjust output current.Increase the output current when
rotating clockwise. Note: It is not keeping a fixed output current. When the load
current reaches the set current value, the module starts to fix output this
current value.
6>.ON LED: Green Output indicator.It will turn ON when there is a output at
output terminal.Otherwise it is OFF.
7>.CC LED: Red Constant current output indicator.It enters the constant current
state when the load current reaches the set current and CC constant current
indicator turns ON.
8>.Input terminal: There are three input methods:
8.1>.Method 1: Standard Type A USB Male . It just can input DC 5V.
8.2>.Method 2: Micro USB Female. It just can input DC 5V.
8.3>.Method 3: IN+ and IN- pads. It can input DC 4.0V-13.0V.
8.4>.It can only choose one input method.
9>.Output terminal: KF-301-2P 5.08mm blue terminal. It can output DC
0.5V-30.0V.
5.Calibration:
1>.ZK-DP2 can calibrate output voltage and output current.
2>.Calibrate output voltage:
Long press right button when display output voltage into calibrate output
voltage, then the screen will be flashing.
Short press left button to decrease the value. Short press right button to
