Dewalt Laser Distance Meter DWHT77100 (0.2 to 30 m Range, Laser Class 2, Measurement Tolerance: +/- 3 mm / 10 m, Length, Areas, Volume & Pythagoras Measurements, Easy Operation)

Product Information

Switch the device on/off several times. If error still occurs, return device to Service Center or Distributor If you need to measure the height of a tall object (e.g., a tall building), you can calculate the height based on the distances from the same point to 2 or 3 points on the object. The tool will use the Pythagorean Theorem (A2+B2=C2) to calculate the height. Measure a distance with two measurements Total Tools reserve the right to change or withdraw free delivery at any time. Estimated Delivery Timeframes Press and hold the gear button (Figure A ) for 3 seconds. The measurement reference location icon (Figure C ) will flash on the display window.

Special event, club or membership offers, third party promotions or prices not available to the general public The DWHT77100 tools emit a visible laser beam, as shown in Figure A . The laser beam emitted is Laser Class 2 per IEC 60825‑1. Once the current measurement is taken (the device is not in Continuous Measure mode), you can change the unit of measure from decimal ft (6.21 ft) to fractional ft (6'02"9/16), fractional ft to meters (1.894 m), meters to inches (74 9/16 in), or inches to decimal ft. Point the laser at the top of the tool laser (Figure A ) toward the wall or object whose distance you need to measure. To change the measurement unit, hold the gear button (Figure A ) for three seconds to enter the units menu. Press the on button to confirm your reference location. Once confirmed, the current unit of measurement will be displayed, press the gear to change units and the on button to confirm.Should you find one day that your DeWALT product needs replacement, or if it is of no further use to you, do not dispose of it with household waste. Make this product available for separate collection. From the same point, aim the laser straight ahead toward the center of the building or object (Figure J3). Press the gear button (Figure A ) three times to show the indirect measurement height on the display window (Figure E ). Slide the pins at the bottom of the battery door into the notches in the battery compartment (Figure E ).

Point the laser (Figure A ) toward the wall or object whose distance you need to measure (Figure F). From the same point, aim the laser straight ahead toward the lowest point of the building or object (Figure I3). DO NOT mix old and new batteries. Replace all of them at the same time with new batteries of the same brand and type. Position the tool at one end of the target and point the laser dot across the length. (Figure H ) shows where to position the tool if you are measuring from the top of the tool.) View the Volume measurement at the bottom of the display window (Figure C ). Measuring the Height of a Tall Object

Press the gear button (Figure A ) three times to show pythagoras (Figure B ) on the display window. You can use the distance to two points on a tall object (Indirect Height) to determine its height (Figure I1).
