STPT objective lens adjustment (troubleshooting #1)

(A) If the brain cannot be visualized at any set depth by the Piezo Amplifier, clockwise or counterclockwise turns of the large screw next to the objective lens will allow for fine adjustment of the objective lens height.

(B) Larger adjustments of the objective lens height may be made by holding the platform of the objective lens in one hand and gently releasing/tightening the screw as shown in this figure, while being careful to not let the platform drop during this process.
