Calibration instructions:
  • The module has calibration function, no need to worry if the measurement is not accurate.
  • If you find that the measuring values are not accurate or values are stuck, and left and right buttons can not adjust  voltage, please do as follow:
  • Calibration method:
    • First, in the case of power off, press and hold the left button and access to power, then the display starts flashing, release the button.
    • Next, measure the output voltage with a multimeter and press the left and right button to adjust the value until the multimeter displays close to 5V, such as 4.98V, 5.02V.
    • Finally, access to power, then the calibration is complete. Error can be less than 0.04V, if the error is larger, you can try again.
Package included:
  • 1 x DC-DC Adjustable Step-down Power Supply Module
