The zoom knobs have click-stops at 1x, 1.2x, 1.6x, 2x, 2.5x, 3.2x and 4x magnifications. The click stops are a bit hard, but the zoom knobs rotate with little resistance once the "threshold" out of a click-stop has been passed. My questions are with respect to this click-stop mechanism.
- Is it possible to remove the click-stops and let the zoom knob rotate smoothly? Alternatively, is there a way to adjust the click-stops to require a lower force to rotate the zoom knob?
- Does removing the click-stops involve a risk that the zoom will slowly "sag" to the lowest/highest magnification instead of remaining at the set magnification? If so, is there a way to adjust the friction of the zoom knob after removing the click-stops?
- Does anyone have a service manual for this microscope?
