3. Method of Operation 3.1 Setting and Levelling a. To adjust tripod, and let the flat part of tripod in a leveling position, with its height basically in the same line of the telescope and the operator's eyes. b. To set the instrument on tripod, and to connect the instrument to the tripod with the central screw. -
Page 8: Staff Reading
3.3 Staff reading a. When the instrument aiming at the staff, the reading of the center line is the altitude. (Fig.3) is 1.614m b. To have the readings respectively for the upper line and the lower, the distance from station point to the staff will be（upper line Fig 3 reading-lower line reading）×100. -

4. Checking and adjusting Before leaving the factory, each centerline is properly adjusted, the centerline is properly adjusted, the centerlines may deviate from proper position after transportation or long time operation. So to check and adjust the main centerlines is necessary before measuring and surveying is field work. -
