Single distance measurement
In Single distance measurement mode, aim the laser beam at the target and press (5). The value will be displayed on the screen.

Continuous measurement
In Single distance measurement mode, press (5) for 3 seconds. The device will keep taking measurements one after another. MAX, MIN, and the last measured values (Fig. B) will be displayed on the screen.

Area measurement
Select the Area measurement mode. Aim the laser beam at the target and press (5) to measure 2 sides of the target. The area will be calculated automatically (Fig. C).

Volume measurement

Select the Volume measurement mode. Aim the laser at the target and press (5) to measure the length, width, and height of the threedimensional target. The volume will be calculated automatically (Fig.D).

Calculations with 2 additional measurements (Pythagorean theorem)
Select the Calculations with 2 additional measurements (Pythagorean theorem) mode. Aim the laser at the target and press (5) to measure the lines А and В (Fig. E). Line C will be calculated automatically.

Calculations with 3 additional measurements (Pythagorean theorem)
Select the Calculations with 3 additional measurements (Pythagorean theorem) mode. Aim the laser at the target and press (5) 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.
Note! The length of line C will not be displayed.

Addition and Subtraction

Aim the laser at the target and press (5). Press (9), then press (5) again to plus another value. The summation will be calculated automatically. The subtraction works accordingly with the minus button (6).
Note! The addition and subtraction functions are available in Single, Area, and Volume measurement modes.

History records
Press (9)/(6) to view the recorded values. Press (7) to delete the recorded values one by one.
