14.2 Use of the microscope (B-510FL)
1. Turn on the power supply ① for the mercury bulb
and wait 5 minutes for the arc to stabilize. (Fig.
67).
2. Move the filter selector ② to one of the four
available positions until the click stop. (Fig. 68).
•
The microscope has a 4-position filter holder
slider. The positions 1 and 2 are empty to house
additional filters, position 3 houses a B filter and

14.2.1 Use of the shutter
•
The microscope is equipped with a shutter
③ located on the right side of the fluorescent
illuminator. (Fig. 69)
1. Close the shutter by interrupting the observation
for a limited time and not subjecting the sample
to unnecessary lighting in the period in which it
is not observed. (Switching off and switching on
frequently the HBO lamp considerably reduces its
duration).
•
This precaution is not necessary in the case
of the LD1 and LD2 models: the LED can be
switched on and off without any problem.
