Gravity: MiniQ Robot Chassis Encoder

Q: I have a question about the encoder. In the process of adjusting the screws, I have turned a screw out of range and don't know which way to turn it back. Is there one direction i should turn it to 'start from zero'?

You can turn it in clockwise or reversely to adjust the resistance value, range 0-30KΩ. And the valid adjustable angle is 260°±20°. To make it easier to understand, it means if you rotate it in 360°, it will keep the same resistance value.
