Distance Estimation with the OL28X

The OL28X can be used to estimate distances between the unit and the staff

with the use of the “Stadia” lines whilst looking through the eyepiece.

By using the plumb bob hanging from under the locking screw of the tripod

the exact position of the dumpy level can be marked on the ground. Next

set the staff up at the point that you want to estimate the distance to and

look through the eyepiece. Note the number of centimeters on the staff

between the top and bottom stadia lines (short lines see page5), multiply

this measurement by 100 and you have the distance between dumpy and

staff in centimeters. e.g. 5cm x 100 = 500cm which is 5m In other words

whatever you read in centermetrs is the distance in meters.

5cm
