Product parameters Technical parameters C-40S/50S/70 Range: 0.1m-40m/50m/70m Material: ABS , ntegrated body, no welding Battery capacity: 280mA Unit of measurement: m, ft, in Minimum display: 1 mm Accuracy: 2mm Single measurement time: 0.4-4 second Laser cla: Cla II Laser type: 620-690NM Laser power: <1mw Data storage: 20 group Battery type: Lithium 3.7V Operating temperature: 0-40 Storage temperature: 10-60 Automatically turn off the laser: 30 second Automatic shutdown: 180 second Size (length * width * height): 82*25*17mm Weight: 33g Functions: single measurement, continuous measurement, area measurement, volume measurement, Pythagorean measurement, benchmark change, USB charging Product Instructions Single/multiple measurement After the machine is turned on, the instrument automatically enters the single measurement mode, and the laser point is aimed at the target to be measured. When there is no measurement data on the display surface, long pre the ON/DIST button, and the instrument enters the continuous measurement mode Area measurement The two side lengths of the object are measured separately, and the area measurement result is immediately displayed in the main display area of the screen Volume measurement The three side lengths of the target object are measured separately. After the measurement is completed, the volume measurement result will be automatically displayed in the main display area of the screen Pythagorean measurement Measure the length of the hypotenuse for the first time, keep the measurement reference point of the instrument unchanged, and measure the length value of the right-angle side. The height value of the right-angled triangle will be displayed in the main display area. Measurement standard switch After the instrument is turned on, the measurement reference is the back reference by default. In the reference switching mode, pre the ON/DIST key to switch to the front reference mode Measurement unit switching After the instrument is turned on, the measurement unit is M. In the unit mode, pre the ON/DIST key to switch the unit. The supported unit is M/IN/FT Historical data query In the storage mode, pre the ON/DIST key to view the measurement data storage records. The smaller the number, the newer the measurement value. Up to 20 sets of historical data can be viewed
