tance adjustments.

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.

* 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
