ADJUSTMENT
AND OPERATION
Turning On The Lamp
(Figure 15)
Connect the power cord, then set the main
switch
①
on the side of the base to the “on”
position (“
－
”).
Adjusting The Brightness
(Figure 16)
Rotate the brightness adjustment knob (2)
clockwise to increase the brightness.
Conversely, rotating the knob decreases the
brightness.
Using the lamp at its lowest acceptable
intensity will increase the life of the lamp.
Adjusting the Tension
Adjustment Collar
(Figure 17)
The tension of the coarse focusing knob
(3)
has already been properly adjusted.
Use the supplied tension adjustment wrench to
adjust the tension adjustment collar (4).
Rotating the collar clockwise increases the
tension on the coarse focusing knob. A counter-
clockwise rotation will decrease the tension on
the coarse focus knob.
The coarse focusing knob is too loose if the
nosepiece descends on its own or if the
specimen loses its focus shortly after focusing
with the fine focus knob (5). Adjust the tension
adjustment collar so these do not occur.
