It is best to set the feel of the microscope before attempting to use the microscope so the user comfort is
optimized for the microscope procedures.
5.3 Counterbalancing Adjustment
Counterbalancing is done to ensure the microscope head moves with very little pressure (typically from user
pressing on the eyecups) To do this the weight of the microscope head must be counterbalanced with the
spring arm.
The upward lift of the spring arm assembly can be adjusted to match the weight of the microscope and its
accessories. This adjustment is called “counterbalancing”. Before adjusting the counterbalance, ensure that
all accessories are installed on the microscope and the spring arm tension adjustment knob is loose. To loosen
the spring arm tension adjustment knob turn the knob clockwise. Insert the 3/16” hex wrench into the center
hex-socket screw (located under the end of the spring arm assembly that attaches to the horizontal arm) and
turn the tool to the right (clockwise) if the microscope falls when released, or turn the tool to the left (counter-
clockwise) if the microscope rises when released.
See Figure 5-3
