operation

When power on and displaying normally, with each switch of the knob to select the function settings, you may turn the knobs to adjust the required the settings. After settings and no further operation within 3 seconds, the display returns to idle and it automatically confirms the current settings, and the setting values will be shown at the bottom of screen; when setting up constant voltage or current, a dash will appear under the V or A, respectively.
Turn off the power, the unit will automatically save the settings. And when power on again, the screen shows the parameters of the last settings.
1:ncoding button
Press the button to select functions. Switch it to adjust the required settings; when adjusting voltage or current, quickly switch the button to achieve coarse tuning(+/- 0.1 V/A), or slowly for fine tuning(+/-0.01V/A)

2:onstant voltage function
For cell phones able to power on, the over-current protection value can be set after setting the voltage; Generally, set 1 A for phones with smaller screens, 2 A for phones with larger screens, moderately depending on user experience. Maximum current can be set up to 3A.
3:onstant current function
For cellphones enter over-current protection mode once power on, compulsory power supply is a must. Setting up the constant current can solve such issue. (Power source cannot enter over-current protection). The usual solution to this is to apply constant current and compulsive power supply time to diagnose the problem; faulty circuit will overheat or breakdown components. Maximum constant current can be set up to 2.00 A.
