micro LM-100 Laser Distance Meter Volume Measurement 1. Press Area/Volume button . The symbol appears in the display. The distance to be measured will flash in the symbol. 2. Press Area/Volume button again, the symbol for volume measurement appears in the display. The distance to be measured will flash in the symbol 3. Press ON/Measurement Button ment (e.g. length). to take the first measure- 4. Press ON/Measurement Button measurement (e.g. width). again, to take the second 5. The result of the area calculation is displayed in the third line; the individually measured values are displayed in lines 1 and 2. 6. Press ON/Measurement Button again, take the third distance measurement (e.g. height). The value is displayed in the second line. The result of the volume calculation is displayed in the third line. Indirect Measurements Indirect measurements are used when a direct measurement is not possible. Indirect measurements are calculated from measurements of the hypotenuse and one side of a right triangle (triangle with a 90 degree angle). For instance, if calculating the height of a wall from the ground, measurements would be taken to the top of the wall (hypotenuse), and perpendicular to the line between the two measurement points at the wall base (side). From these two measurements, the distance between the two measurement points is calculated. Indirect measurements are less accurate than direct measurements. For greatest accuracy with Indirect Measurements, hold the micro LM-100 in the same position (only changing angle) for all measurements. Make sure that the laser beam is perpendicular to the line between the measurement points when measuring the side of the triangle. All measurements need to be to points on a single straight line. Using Two Points Figure 7 - Indirect Measurement Using Two Points 1. Press Indirect Measurement Button once. The symbol will show in the display. The distance to be measured will flash in the symbol. 2. Press ON/Measurement Button to turn ON the laser, aim the laser at the upper point (1) and trigger the measurement. The measurement will be displayed in the first line. 3. The next distance to be measured will flash. 4. Press ON/Measurement Button to turn on the laser, keeping the instrument as perpendicular to the line between the measurements as possible, Press ON/Measurement Button again to measure the distance result of the horizontal point (2). The measurement will be displayed in the second line. 5. The result of the calculation is displayed in third line. 10 Ridge Tool Company
