Hi guys! I am quite confused with the pattern and direction on how adjustment screws of my Leica tribrach are to be operated as the cross hairs movement appears not consistent when I tried it my way. As far as I can remember, the turning of screws shall be in alternate fashion but it seems not working particularly when trying to reverse the movement. Anybody can help me with a link? By the way, I am using the SECO adjustment ring. Thank you.
