Vertical Beam Accuracy (See figure
• Measure the height of a door jamb or reference point

ON. Aim vertical beam towards door jamb or reference
point. Mark points P

• Calculate the maximum offset distance and compare
to D .

maximum offset distance the tool must be returned
to your Stanley Distributor for calibration.
