NEW free shipping CP-3008 Handheld LCD ultrasonic Laser Distance Meter Measurer 0.91-30 Meter Digital laser ruler

Description:

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.

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.
