Press the Read key to make a new measurement. Single Pythagorean Theorem measurement mode The Pythagorean Theorem measurement mode is used to measure distances that cannot be measured directly because an obstacle would obstruct the laser beam or no target surface is available as a reflector. Correct results are achieved only when the laser beam and the sought distance form a precise right angle (90). In the illustrated example (Fig. 15), the length BC is to be determined. For this purpose, AB and AC mush be measured. AC and BC must form a right angle. 1. Press the Mode key to choose single Pythagorean Theorem measurement mode (Fig. 16). 2. The blinking line in “ ” indicates the distance AB to be measured. 3. Press the Read key to turn on the laser beam; the laser indicator blinks. 4. Position the tool to aim the laser at the target B. 5. Press the Read key to display the measured length of AB in the first row of the screen (Fig. 17). 6. The blinking line in “ ” indicates the distance AC to be measured. 7. Without changing the tool position A, aim the laser dot perpendicularly to the target C. 8. Press the Read key again to display the calculated length of BC in the lowest row of the screen; the distance AC will be displayed at the same time in the second row (Fig. 18). 9. Press the Read key to make a new measurement. NOTES: The distance AC should be shorter than the hypotenuse (AB); otherwise the LCD will display “Err008” reminding you to re-measure the distance AC. When taking the two measurements, make sure they are taken from the same starting point (A) and the second measurement is perpendicular to the target C. Taking the measurements correctly will help result in the most accurate calculated distance. Double Pythagorean Theorem measurement Use the double Pythagorean measurement mode when one end of the length to be measured indirectly is higher than the measurement position and the other end of that length is lower than the measurement position. In the illustrated example (Fig. 19), the length BC is to be determined, A is the measurement position. For this purpose, AB, AO and AC mush be measured. AO and BC must form right angles. Fig. 12 Fig. 15 Fig. 17 Fig. 13 Fig. 16 Fig. 18 Fig. 14 Fig. 19 2627 1. Press the Mode key to choose double Pythagorean Theorem measurement mode (Fig. 20). 2. The blinking line in “” indicates the distance AB to be measured. 3. Press the Read key to turn on the laser beam; the laser indicator blinks. 4. Position the tool to aim the laser at the target B. 5. Press the Read key to display the measured length of AB in the first row of the screen (Fig. 21). 6. The blinking line in “” indicates the distance AO to be measured. 7. Without changing the tool position A, aim the laser dot perpendicularly to the target O. 8. Press the Read key to display the measured length of AO in the second row of the screen (Fig. 22). 9. The blinking line in “ ” indicates the distance AC to be measured. 10. Without changing the tool position A, aim the laser dot at the target C. 11. Press the Read key again to display the indirect length of BC in the lowest row of the screen; the distance AC will be displayed at the same time in the third row (Fig. 23). 12. Press the Read key to make a new measurement. Continuous Measurement (Locating) The continuous measurement function (locating) is used for transferring measurements, e.g., from construction plans. In the continuous measurement mode the measuring tool can be moved relative to the target, and the measured value is updated approx. every 0.5 seconds in the display. For example, the user can measure the distance from the tool to a wall and then move away from that wall while the actual distance is displayed continuously, informing the user when the correct distance has been reached. 1. Press the Mode key to choose single-distance measurement mode. If in other mode, press clear key to go back to single-distance measurement mode. 2. Press the Read key and hold it for about 3 seconds to activate the continuous measurement mode. 3. Move the tool until the required distance value is indicated at the bottom of the display. 4. Press read key to interrupt the continuous measurement. The current measured value is indicated in the lowest row of the screen. The minimum and maximum values will be displayed in the first and second row of the screen (Fig. 24). 5. Press the read key again to start the new continuous measuring. Minimum/Maximum measurement This function allows the user to measure the minimum or maximum distance from a fixed measuring point. It is commonly used to measure diagonal distances (maximum values), horizontal distances, or vertical distance (minimum values). The function can be transferred in area, volume, Pythagorean Theorem measurement and single-distance measurement mode. Min/Max function can help eliminate the measuring deviation caused by not correctly holding the tool and aiming at the target. It can help to get an accurate calculation of area, volume and indirect length. 1. Press the Mode key to choose area, volume or Pythagorean Theorem measurement mode. 2. Press the Min/Max key to transfer the Min/Max function. 3. Press the Read key to turn on the laser, aim the laser beam at the target you want to measure and press it again to start the minimum or maximum measuring. 4. Slowly sweep the laser left and right or up and down over the desired target point. 5. Press Read key to interrupt the Min/Max measuring; the minimum or maximum value will be displayed on the related row of the screen as an accurate length for calculation. Fig. 20 Fig. 21 Fig. 22 Fig. 23 Fig. 24 2829 Addition and subtraction The single-distance, area, volume and indirect length can be added or subtracted by the addition and subtraction function. 1. Take the first measurement 2. Press “Plus/Minus” key, the symbol + or - will show behind the battery indicator. 3. Take the second measurement 4. The sum of the measurements will be displayed in the lowest row of the screen, and the last measurements will be displayed at the same time in the upper row of the screen. 5. Follow the same method to make additional calculations. Working with the tripod (not included) The use of a tripod is particularly helpful for greater distances. The measuring tool can be screwed onto a commercially available tripod using the 1/4” thread on the bottom side of the housing. 1. Mount the tool to the tripod. 2. Set the measuring reference to the thread (Fig. 25). 3. Start to take measurements. 4. Error signals The following error signals may appear on the LCD of your tool during measuring: CodeCauseSolution Err001The reflected laser light is too intense. Do not direct the laser at a highly reflective surface; cover the surface with white paper if necessary. Err002Out of range, The measuring range for this tool is from 0.1 to 50m. Take measurement within the range of 0.1 to 50m. Err003The target provides poor reflection of the laser. Change the measuring target or cover it with a piece of white paper. Err004The temperature is too high. Wait until the measuring tool has reached the operating temperature (-10 to 50C) Fig. 25 Err005The temperature is too low. Wait until the measuring tool has reached the operating temperature (-10 to 50C) Err006Low battery, a reminder to replace the batteries. Insert new batteries Err007Strong vibration, or the tool was moved quickly when measuring. Always keep the tool steady Err008Wrong input, the length of one side of the right triangle as measured is longer than the hypotenuse. Re-measure; the hypotenuse is always longer than the first side length MAINTENANCE This digital laser distance meter has been designed to be a low-maintenance tool. However, in order to maintain its performance, you must always follow these simple directions. 1. Always handle the tool with care. Treat it as an opti
