Features:

How to use:

1. Press the button in a short time (1 second) so that "in" LED lighted, the voltmeter shows the value of input voltage.

2. Press the button in a short time (1 second) again so that "out" LED lighted, the voltmeter shows the value of output voltage.

3. Rotate the top screw of potentiometer clockwise to boost the value of the output voltage, anti-clockwise to reduce it.

4. Long press the button between 1 and 4 seconds to turn off the voltmeter.

How to adjust accuracy of input/output voltage:

(for the person who need a highly accurate value of number)

1. Long press the button for more than 4 seconds, then release, voltmeter and "in" LED flash in synchronization entering into the input voltage calibration mode.

2. Press the button in a short time (1 second) to adjust the value (range from -0.5 - 0.5V)

3. Long press the button for more than 2 seconds and then release to enter the output voltage calibration mode.

4. After calibration, long press the button for more than 2 seconds all parameters will be saved automatically and back to the voltage display.

Additional Features

  • Nice design: with 150KHz internal oscillation frequency, features low power consumption and high efficiency; When the output voltage cannot be adjusted and is always equal to the input voltage, please turn the potentiometer counterclockwise for more than 10 turns, and then use the module to adjust the voltage normally; This is because when the module leaves the factory, the default output voltage is about 20V
