For a home project, I have recently purchased an OLYMPUS SZ4045CHI (used) with an attached OLYMPUS SZ-STP unit for vertical movement. If I use the knob of the the SZ-STP to move the microscope unit up, it is unable to keep the microscope unit in is place and the microscope is slowly drifting down an settling at the bottom most position (due to the its weight) . Can I fix this issue?
Any help will be appreciated.
