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:
Â
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.
