Leveling Instrumentation and Adjustment

Course Number
This course is intended to help the intermediate level technician or professional who is involved in significant leveling activities.  It is also recommended for supervisors, project managers and field engineers who supervise crews performing leveling.  This course starts with an introduction to the various types of levels, beginning with dumpy and tilting levels, before moving into the design concepts of the automatic level, whether optical or digital.  Additional discussion on leveling equipment, such as rods, hand levels, micrometers, zenith and nadir plummets, is covered.  The course concludes with an overview of basic checks to ensure proper automatic level function, including parallax, cross hair horizontality, level bubble, and the horizontal cross hair position using the two-peg test.

Suggested Prerequisites:
Differential Leveling ​​
and/or experience background on the leveling process.  Some learners may also benefit from Errors in Surveying, Systematic Errors I, Systematic Errors II, Random Errors I, Random Errors II.
Learners who successfully complete this course will receive a certificate of completion for 1 professional development hour.
