2/18/2023 0 Comments Laser point measureThis instrument is designed to take accurate measurements and will meet your expectations if used properly. Once you get comfortable with how the LDM operates you will naturally begin to trust the results. Likewise, if a surface has a highly reflective surface (or is in direct sunlight) the laser distance measure will not receive the sufficient return signal to determine a distance.Īs with any new technology, start off easy and work your way into more advanced measurements. If this surface has poor reflective properties the return signal will be too weak for the instrument to calculate the distance. There is a lens that receives the reflected beam and determines (by the rate or speed of return) the distance of the surface or object. To explain in simple terms how these tools work: A laser beam is emitted from instrument and once it makes contact with a surface the beam is reflected back to the instrument. This is true of all laser distance measuring products and is not a defective issue. Attempting to measure highly reflective, porous, translucent, water covered or bright sunlight covered surfaces will be difficult. The key to taking successful measurements with any laser distance measure product begins with aiming at a solid target. While a laser distance measure tool is remarkably fast and efficient there are situations which will challenge any make or model. Level vial for achieving the final measurement in the Indirect Measuring modes (90 degree measurement required to calculate height or width).Adjustable measurement reference settings (Rear, front & tripod thread locations).Tripod thread (1/4"-20) enables precise long distance measuring (Essential to achieving accurate Pythagoras Indirect Measurements).3-Indirect Measuring Modes (single & double Pythagoras and partial height Pythagoras - see below for a further explanation Indirect Measuring).Patented Sound Activated Measuring Mode (no more waiting for the countdown timer).Key features of the Johnson laser distance measure: A laser distance measure tool will help you get the job done faster and more accurately. This tool is great for any estimating material list: trim, drywall, cabinetry, conduit, pipe, ducts, to exterior siding. It is capable of recording measurements to 1/32" for skilled trades people requiring a tight read. With a simple 1-2-3 measuring system (Point-Press-Done), the Johnson Laser Distance Measure is the right measuring instrument for any jobsite. View all laser distance measures from Johnson Level. How to Calibrate a Laser Distance Measure.How to Calculate Distance Using Laser Distance Measure.For the whole operating temperature range the maximum deviation increases by ± 0.1°. Additional angle related deviation of ± 0.01° per degree up to ± 45° in each quadrant. Applies for 100 % target reflectivity, background illumination between 10,000 lux and 30,000 lux. The maximum tolerance may deteriorate to 0.1 mm/m (0.003 in/ft) between 10 m to 30 m (32.8 ft to 98.4 ft) and to 0.15 mm/m (0.005 in/ft) for distances above 30 m (98.4 ft). Tolerances apply from 0.05 m to 10 m (0.001 ft to 32.8 ft) with a confidence level of 95 %. Applies for 10 % to 500 % target reflectivity, high background illumination, -10 ☌ to +50 ☌ (14 ☏ to +122 ☏). Applies for 100 % target reflectivity (white painted wall), low background illumination, 25 ☌ (13 ☏). Battery life (2 x AAA) 1.5 V NEDA 24A/IEC LR03ĬAN/CSA-C22.2 No.
