TANCE ADJUSTMENT
Before using the instrument, always carry out the diopter compensation and interpupillary dis-
tance 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.
Insert test rod in the hole in chinrest with the flat surface at the top of test rod facing the micro-
scope.
(2) Preparation of illumination unit
* Turn the power switch ON. Set the brightness control switch at the '0.1' position.
* Turn aperture and slit length control wheel until slit diameter becomes 14mm, then turn slit
width control knob to set slit width to maximum.
* Use joystick gross control to move base so that illumination is provided on the test rod.
* Then use joystick fine control to move base so that a 1 to 2mm width slit image focuses
sharply on test rod when seen naturally by eye.
(3) Diopter compensation
Independently set the diopter setting for each eyepiece as follows.
* First, turn the eyepiece ring in a counterclockwise direction until it stops.
