    Objectives

    Scanning Objective: 4X

    Low Power Objective: 10X

    High Power Objective: 40X

    Oil Immersion Objective: 100X

    Rules for Using theMicroscope1. Always start off with

    the lowest magnificationobjective and work upto higher power oneobjective at a time.

    2. Always observe theobjective as it is rotatedinto place to ensure itdoesnt crash into the slide.

    Mechanical Stagemicroscope slide

    Rules for Using theMicroscope1. Lower the stage to its

    lowest point beforeplacing a slide on thestage.

    2. Be sure the scanningobjective is in place.

    3. Raise the stage to itshighest point withoutcrashing the slide intothe objective.

    Rules for Using theMicroscope4. Focus initially by

    lowering the stageusing coarse focusadjustment knob.

    5. After getting a closefocus with the coarsefocus adjustmentknob, improve it usingthe fine focusadjustment knob.

    Rules for Putting Away theMicroscope1. Rotate scanning

    objective into place.2. Lower the stage to its

    lowest point.3. Clean lenses, stage,

    body, and base ifneeded.

    4. Replace protectivecover overmicroscope.
