Adjustments of Level Circuits

When errors accumulate in a level circuit, adjustments are made to ensure the final results are accurate. The process of adjustment distributes errors equally across all stations in the survey.
If e is the total error between the initial elevation and the final closing elevation, and there are n number of stations, the correction applied to each station is:

Correction per station =𝑒/𝑛

This corrected value is then applied to the computed reduced levels (RLs) of each station to obtain the adjusted reduced levels.
