Description of the function:
Button:
-Select” button: short pressure switch between voltage, current, power, wheel display; Long press or exit calibration mode;
-On / off button button: short pressure control of the output end that turns on or off; long pressure: set the default power on to be off or on, press to release more than 3 s, it will be displayed for each power-by default there is an output, and the screen off means there is no default output each time turn on the energy.
Potentiometer:
-The current adjustment potentiometer CC turns clockwise to increase the current limit value. When the charging current reaches the limit current, it enters the constant current state (keep in mind that the output current can be increased without adjusting the potentiometer.) At constant voltage, the output current only depends on the load, varies according to load);
-Maximum output current (constant current value) Configuration method: Switch to the current screen, shorten directly the output terminal to adjust the DC potentiometer.
-The CV voltage adjustment potentiometer rotates clockwise to increase the output voltage.
The indicator lights:
-CC – Constant current indicator light, bright when the constant current (red);
-ON – Status indicator on the output (green);
Input and output ports:
-Input: left side, USB male, micro USB, pad three ways to select as input
-Output: right side, blue 2P terminal as output
Accuracy calibration method:
-When the output voltage is calibrated, the digital tube always displays the voltage. Press and hold the “SELECT†button for more than 3 seconds to release. The digital tube flashes. Press the “SELECT†button briefly to increase the voltage value by one unit. Short press the “ON/OFF†button voltage. The value is reduced by one unit. When the output voltage is low, it may take several times to see the value change 0.1V;
-Output current calibration When a digital tube always displays current, press and hold the “SELECT†button for more than 3 seconds to release, the digital tube flashes, short press the “SELECT†button, the voltage value increases by one unit, short press the “ON/OFF†button voltage. The value is reduced by one unit. It may take several times to see the value change 0.01A. Press and hold the “SELECT†button for more than 3 seconds to release and exit the calibration mode.
Note:
-The calibration is more accurate when the current is greater than 1A; the display error is large when the output current is less than 0.05A.
-It may not be displayed when the output current is less than 10-40mA.
