5.2 Specimen Placement
The sample clips are for xing the object being observed, and can eecvely prevent vibraons in the
environment from moving the image. Steps for securing specimen:
1. Loosen both spring screws.
2. Place sample on stage and posion in desired locaon.
3. Posion both sample clip arms onto sample.
4. Tighten sample clip arms using spring screws.
TIP: Use gloves to avoid leaving nger prints
on samples when adjusng posion on stage.
The illumination adjustment knob is located on the stem of the VM-500, near the backside of the

the Coarse Adjustment knob until the
object is in focus on the LCD monitor.
2. If the object is too far or too close,
adjust the Lens Height Adjustment
screw and repeat step 1
