Hello all, my Q if anyone knows - there is a tiny smd potentiometer on the back, does this adjust the led brightness, or perhaps the voltage reading, or something else? - thx
It is used to calibrate your deviceā¦use a multimeter and test a known voltage, then apply that to your screen and turn the screw (if needed) to make the reading match the previous measurement (known voltage)
Ok very good, thx for that info.
