***SETTING MODE

1.Normal Display Mode: 1>.Default normal display. 2>.Short press button ‘STOP’ to enabled/disabled output. 3>.Long press(keep press 2second) button ‘STOP’ to switch display input voltage and output voltage. 4>.Short press button ‘STOP’ to clear value when display capacity, energy and time. 5>.Short press button UP or DOWN button to adjust output voltage at default display mode. LCD display CV symbol. 6>.Short press SET button:Switch display output current A, output power W, capacity Ah, energy Wh, work time h. 7>.Long press SET button:Keep press 1second to adjust output constant current value. Then press button UP or DOWN to adjust output constant current to set value. LCD display CC and SET symbol. 8>.Long press SET button:Keep press 3second enter into parameter set mode.It is used to set LVP/OVP/OCP/OPP/OAH/OPH/Default Power-ON State. 9>.Long press SET button:Keep press 5second to lock and unlock output voltage and output constant current values.

2.Parameter Set Mode: 1>.Long press(keep press 3second) SET button enter into parameter set mode at normal display mode. 2>.Short press SET button to switch select parameters: LVP, OVP, OCP, OPP, OAH, OPH, OHP. 3>.Press button UP or DOWN button to set value directly for LVP/OVP/OCP/OPP parameters at Parameter Set Mode. 4>.User need press ‘STOP’ button to enabled/disabled OAH/OPH/OHP three parameters and then press UP or DOWN buttons to set value.LCD will display ‘----’ if disabled OAH/OPH/OHP function. 5>.Long press button ‘STOP’ to set statistical range value when select OAH or OPH.The range of OAH is 9.999Ah/99.99Ah/999.9Ah/9999Ah.The range of OPH is 9.999Wh/99.99Wh/999.9Wh/9999Wh. 6>.Long press(keep press 3second) SET button to save and quit parameter set mode to normal display mode.

Package Include

• 1 x Board
• 1 x Heatsink

How to set-up before use:

1. Make sure that the power input is not greater than input voltage writen in specification.
2. Set the multimeter to DC Voltage.
3. Gently turn the adjustment potentiometer to your expecting voltage.
