Taking a measurement \u003cbr\u003e- Press MEASURE to turn on the unit. The measurer beeps then the distance between the measurer and the point you measured appears. \u003cbr\u003e- Hold the bottom of the measurer flat against a wall, about halfway between the floor and ceiling. Be sure there is a clear path to the point you want to measure and that your head or hands do not block the front of the measurer. \u003cbr\u003e- Repeatedly press FEET\/METER until FEET appears (to measure in feet ) or until METER appears (to measure in meter). \u003cbr\u003e- Press and hold down MEASURE to take a continuous measurement \u003cbr\u003e2. Stabilizing the measure \u003cbr\u003e- Your measurer is sensitive to changes in temperature and humidity. Before you use the measurer, wait about 15~30 minutes for it to stabilize to the current rooma is temperature. \u003cbr\u003e3. Measuring Tips \u003cbr\u003e- Some types of curtains and blinds can absorb sound waves, causing measurements to be inaccurate. If you are measuring distances in a room with curtains, open the curtains before measuring the distance to a window behind them. Also, be sure that the window is closed. \u003cbr\u003e- If there is not a clear path between the points where you are measuring, you might receive a false reading from sound waves bouncing off objects such as chairs, tables and objects with uneven surfaces. If you are not sure if a measurement is correct, move slightly to one side then measure the distance again. \u003cbr\u003e- If the surface of a wall you are measuring is not solid and flat, of if you are measuring in a narrow corridor, you might receive a false reading. If this happens, use a solid surface to measure or move to the center of the corridor. \u003cbr\u003e- To measure a distance longer than 60 feet (18.288meters), select a point in the middle of the room (for example), measure from the center of the room toward each side, then add the two measurements. \u003cbr\u003e4. Calculating volume \u003cbr\u003e- To find the volume of a room, measure the height, width and the length of the room and store each measurement in a different memory location (see \"Saving a Measurement\"). Then press VOLUME, the volume calculation result appear. \u003cbr\u003e5.
