PREPARATION-DIOPTER COMPENSATION AND INTERPUPILLARY DIS-
TANCE ADJUSTMENT
Before using the instrument, always carry out the diopter compensation and interpupillary distance
adjustments.
(1) Use of the focusing test rod
The focusing test rod, which is a standard accessory, is used to establish the proper micro-
scope settings for each use.
The rod is inserted in the hole, which normally contains the Hruby lens guide plate. Place the
rod in the hole and turn it so that the flat black surface is perpendicular to the microscope's
objective lens.
(2) Preparation of illumination unit
Turn the power switch ON and place the brightness adjustment knob in an intermediate posi-
tion, then set the slit width control knob so that slit is approximately 2 to 3mm wide.
(3) Diopter compensation
To establish the current dioptric setting:
* First, turn the eyepiece ring in a counterclockwise direction until it stops.
* Now, turn the ring in a clockwise direction until a sharp, slit image is seen on the focusing
test rod.
