Single distance measurement

When the device is turned on, it goes into single distance measurement mode automatically. Press (2) to turn the laser on. Aim the laser beam at the target and press (2). The value will be displayed on the screen.

Continuous measurement

Press (7) to enter continuous measurement mode. Press (2) to turn the laser on. Aim the laser beam at the target and press (2) again. The device will keep taking measurements one after another. MAX, MIN, and the last measured values (Fig. B) will be displayed on the screen.
Press (9) to stop the continuous measurement, and press (9) again to return to single measurement mode.

Area measurement

Press (4) to enter area measurement mode. Aim the laser beam at the target and press (2) to measure 2 sides of the target. The area will be calculated automatically (Fig. C).

Volume measurement

Press (4) to enter volume measurement mode. Aim the laser at the target and press (2) to measure the length, width, and height of the three-dimensional target. The volume will be calculated automatically (Fig. D).

Calculations with 2 additional measurements (Pythagorean theorem)

Press (4) to enter the calculations with 2 additional measurements (Pythagorean theorem). Aim the laser at the target and press (2) to measure the lines А and В (Fig. E). Line C will be calculated automatically. Calculations with 3 additional measurements (Pythagorean theorem), method 1 – legs summation
Press (4) to enter the calculations with 3 additional measurements (Pythagorean theorem), method 1 – legs summation. Aim the laser at the target and press (2) to measure the distance D by making 3 additional measurements. Make measurements of lines А, В and С one by one (Fig. F). Length of line D will appear in the main line on the display. Calculations with 3 additional measurements (Pythagorean theorem), method 2 – legs subtraction
Press (4) to enter the calculations with 3 additional measurements (Pythagorean theorem), method 2 – legs subtraction. Aim the laser at the target and press (2) to measure the distance D by making 3 additional measurements. Make measurements of lines А, В and С one by one (Fig. G). Length of line D will appear in the main line on the display.

Addition and Subtraction

Direct the laser beam at the target and then take a measurement. Press (3) to add the next measurement (plus icon appears on the screen). Take the next measurement.
To subtract the measurement, press (3) and hold it for 2 seconds (minus icon appears on the screen).

History records
