8. Operation
8.1 Switching on
When using a gas discharge lamp*, the
external supply unit* must be turned on
separately.
Switch on the microscope at the on/off switch
(37.1).
8.2 Stages and Object Displacement
Lengthening the Coaxial Pinion (telescoping)*
For lengthening, pull the lower grip (38b.1)
downward. Repeat with the upper grip (38b.2).
Torque Adjustment*
The torque for x and y can be individually
adjusted using two knurled rings (38b.2, 38b.4).
Adjusting the Travel Range of the Stage
The travel range in e-w direction of the stage
could slightly decrease after a longer period of
working with the microscope. This can be
corrected as follows:
Move the object guide all the way to the left side
of the microscope to the current end of the
travel range with the coaxial pinion. Push one of
the screws which hold the object guide further
to the left with your hand as far as it will go.
Afterwards move the object guide all the way to
the right. Here also push the screw gently, this
time to the right, to the limit. The original travel
range of the stage is restored.
