3. ASSEMBLING THE MICROSCOPE
3.1 Input voltage
The automatic voltage selection works with a broad range of settings. However, always use a
power cord that is rated for the voltage used in your area and that has been approved to meet local
safety standards. Using the wrong power cord could cause fire or equipment damage.
In case of using the extension cord, use only a power supply cord with a protective earth (PE) wire.
In order to prevent electric shock, always turn the power switch on the power supply off before
connecting the power cord.
Illumination
Halogen: 12V/ 50W
3.2 Illumination (halogen lamp)
The quartz halogen lamp, used as a light source, has higher luminance and color temperature
than
conventional tungsten lamps. The luminance is approximately four times greater.
As long as the lamp voltage is kept constant, the halogen lamp maintains the same level of
brightness and color temperature regardless of whether it is new or nearing the end of its life.
3.3 Focusing block
Focusing block is assembled on pole of the stand, and it could be fixed at any position by the
lock screw.
The fixture dimension for focusing block is Ø32mm.
Movement range for focusing block is 30mm.
3.4 Stand
Stand has a pole whose height is 300mm and diaMeter is Ø32mm.
Adjustor on the pole could prevent focusing block from sliding down.
3.5 Mechanical Stage
Mechanical stage is assembled on the stand.
3.6 Objectives
Lower the stage completely. Screw the objectives into the revolving nosepiece so that clockwise
rotation of the nosepiece brings the next higher magnification objective into position
.
