Data are recorded and computations are done immediately so when the network readings are done, so are the elevations.
Readings and computations are recorded on the left plate of the field book page and support information on the right, Figure C-1.
Although at first glance differential leveling notes may appear a little complicated, they are relatively simple and reflect the leveling process. It is important that running computations be done in the field as data are collected to minimize mistakes. Should a mistake be found, the equipment and crew are able to remeasure immediately.
