# Measuring Functions

Always set up the levelling rod exactly vertically. Point the aligned and focused measuring tool at the levelling rod so that the crosshairs are on the centre of the levelling rod.

##

Read off the height on the levelling rod at the centre line of the crosshairs.

Height measured in the figure: 1.195 m.

##

Centre the measuring tool over the point from which the distance is to be measured.

Read off the height on the levelling rod at the top and bottom lines of the crosshairs. Multiply the difference between the two heights by 100 to get the distance from the measuring tool to the levelling rod.

Distance measured in the figure:
(1.347 m – 1.042 m) x 100 = 30.5 m.

##

Centre the measuring tool over the point from which the angle is to be measured.

Point the measuring tool at point A. Rotate the horizontal circle (10) with the zero point toward the reference mark (9). Then point the measuring tool at point B. Read off the angle at the reference mark (9).

GOL 20 D/GOL 26 D/GOL 32 D: Angle measured in the example: 45°.

GOL 20 G/GOL 26 G/GOL 32 G: Angle measured in the example: 45 gon.
