More Colors/Sizes:
1) Taking a measurement
-Press MEASURE to turn on the unit. The measurer beeps then the distance between the measurer and the point you measured appears.
-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.
-Repeatedly press FEET/METER until FEET appears (to measure in feet ) or until METER appears (to measure in meter).
-Press and hold down MEASURE to take a continuous measurement.
2) Stabilizing the measure
-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 room?s temperature.
3) Measuring Tips
-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.
-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.
-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.
-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.
4) Calculating volume
-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.
5) Calculating area:
-Follow these steps to find the area of any two stored measurements.
-Measure the width and length of a room and store the measurements in M1 and M2 (see "Saving a Measurement").
-Press AREA M1 and M2 the area calculation appear.
6) Adding/subtracting stored measurements
-Measure any two dimensions of a room and store the measurements in memory locations 1 and 2 (see ?Saving a Measurement?)
-Press ALL MEMORY CLEAR.
-Press M1 + M2 then + to add the measurements or M1 - M2 then - to subtract them. The value of the calculation appears.
-To clear the display and do another measurement press ALL MEMORY CLEAR.
