3.2
Lamp and Lamp Cover (Replacing the Lamp)
In order to prevent electric shock always turn the power switch off and
unplug the power cord before installing or replacing the lamp.
Place the microscope on its back and pull back the lamp cover plate.
Firmly insert the lamp into the socket pinholes until it reaches the
limit. Be careful not to tilt the lamp when mounting.
When installing the lamp, do not touch the glass surface of the lamp
with bare fingers. Doing so will cause fingerprints, grease, etc., to
burn onto the lamp surface, reducing the illumination provided by the
lamp. If the surface is contaminated, wipe it clean using lens tissue.
Close lamp cover plate and secure until it snaps into position.
3.3
Halogen Lamp
Tungsten-halogen lamps operate at very high temperatures and may
cause serious burn injuries if handled while hot.
When replacing these lamps, always allow them to cool before
removing them from the lamp socket.
Avoid handing the bulb envelope directly because fingerprints left on
the envelope will be burned into the glass, often initiating premature
lamp failure.
Manufacturers package tungsten-halogen lamps in protective plastic
bags to avoid handling problems.
Use a pair of scissors to cut the bag near the tungsten pins, insert the
lamp into its holder while it still remains in the bag.
Remove the bag, when the lamp is properly positioned in the lamp
socket.
3.4
Specimen Clip
Insert two specimen clips into the holes on the circular graduated
stage surface
3.5
Attachable Mechanical Stage (Optional)
Mount the attachable mechanical stage onto the circular graduated
stage, inserting the two positioning pins at the bottom of the
attachable mechanical stage into the pinholes on the stage surface.
Tighten the clamp screw.
3.6
Objectives
Lower the stage completely.
Screw the objectives into the revolving nosepiece starting with the
reference position so that clockwise rotation of the nosepiece brings
the next higher magnification objective into position.
Note:
The BA310 Polarizing microscope allows you to center three
objective positions with a reference objective
