Preliminaries
• Focusing when taking measurements
1 Using the gunsight, aim the objective lens toward the staff.
2 Turn the horizontal fine motion knobs until the staff is nearly
centered in the field of view, then turn the focusing knob to focus on
the staff.
• If the staff barcodes are out of focus, they will not be readable
and measurements cannot be taken. Make sure they are
correctly focused.
