Levelling – Height Calculation

Calculate the reduced level (RL) of the next station using the current station height, Back Sight and Fore Sight.

Height of Station 1 / RL (m) Back Sight (BS) (m) Fore Sight (FS) (m) Calculate Height New / Clear Reset All

The calculation follows the original Java expression (X1 + X2 − X3) and rounds the result to three decimal places. The current station height is retained when moving to the next station.
