Addition And Subtraction - Levenhuk Ermenrich Reel GM60 Bedienungsanleitung

Calculations with angle measuring and 2 additional measurements (Pythagorean theorem)
Select the Calculations with angle measuring and 2 additional measurements (Pythagorean theorem) mode. Aim the laser at the target
and press (4) to measure lines А and C one by one (Fig. F). Line D will be calculated automatically. The angle will be calculated and displayed
on the screen at the same time.
Calculations with 3 additional measurements (Pythagorean theorem), method 1 – legs
summation
Select the Calculations with 3 additional measurements (Pythagorean theorem), method 1 – legs summation mode. Aim the laser at the
target and press (4) 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
Select the Calculations with 3 additional measurements (Pythagorean theorem), method 2 – legs subtraction mode. Aim the laser at the
target and press (4) 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

Aim the laser at the target and press (4). Press (9), then press (4) 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
