Checking the EDM of a Total Station

Surveying Made Easy

Checking the EDM of a Total Station Permanently mark three or four baselines within the range typical for the user (e.g. between 20 – 200 m / 60 – 600 ft). Using a new Electronic Distance Meter (EDM), or one that has been calibrated on a standard baseline, measure these distances three times. The mean values, corrected for atmospheric influences (refer to the user manual), can be regarded as being the required values. 20 | Inspecting the EDM Measure these baselines with each EDM at least four times per year. Provided there are no systematic errors in excess of the expected measuring uncertainty, the EDM is in order.
