Topcon DL-501 - 14.2 Closure Error

14. CALCULATION FUNCTIONS
60
This function calculates the closure error for closed leveling links and closed leveling loops.
A leveling link ties two different bench marks (with known elevation) together by combining multiple
consecutive routes. The start points and end points of a link are different.
A leveling loop, on the other hand, closes on the same bench mark at which it started.
