Once the plane table is secured to the tripod, what is the correct order of essential tasks to perform at each plane table station?

Explanation

The three primary steps after fixing the plane table are: 1) levelling to ensure the table is horizontal, 2) centering the table precisely over the station point, and 3) orienting the table correctly with respect to the survey lines. The proper sequence is levelling first, then centering, and finally orientation.
