The ULTRASONIC DISTANCE METER + LASER POINTER is a perfect tool to quickly know the distance, area and volume of a room! It can measure distances in a straight-line from 1.5 Feet to 60 Feet. Your distance measurer transmits ultrasonic waves to a point you want to measure. Afterwards, it measures the time taken by the waves to reflect and then calculates and re-transcribes the distance.

Package Content:
1 x Ultrasonic Distance Measurer (battery Not included)
1 x English Manual

Overview
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.
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.
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.
