focus knob on zwo 2600mm duo

I do need to know how much the guide chip focus knob on the 2600mm duo moves the guide chip for one rotation.

I also do need to know the direction. will turning the knob clockwise more the guide chip toward or way from the telescope.

This is for a remote setup, I need to provide some instruction on the changes.

thank you

This direction is to move the guide sensor up, conversely, the other drection is to move the guide sensor down,

Do you have a sense of how sensitive it it ? how much will the chip move for a full rotation ?

thank you
