Tips from the Pros • Take more than one measurement in situations where accuracy is critical. • Take 3-4 measurements from the same position to compare the consistency of each reading. • To accurately measure objects lacking an inside corner from the rear of the instrument, use a scrap piece of drywall or other flat material to extend the corner. Butt the Laser Distance Meter up to the material (as shown).
