Electromagnetic Distance Measurement (EDM) equipment is calibrated on a base to determine 
instrument constants and errors. A series of measurements on a base can also be used to check 
the performance and reliability of the instrument over time and to assess its precision against 
the manufacturer's specifications. This research work, the establishment of Electromagnetic 
Distance Measurement (EDM) calibration base entails the setting up of a functional base where 
calibration of electromagnetic distance measurement (EDM) equipment can be carried out 
within the institution. Two (2) monuments were re-established; including the existing three (3) 
making it a total of five (5) monuments and subdivided into four bays and subsequently carried 
out distance observations. Consequently, the measured distances for each of the bays were 
entered into the Least Squares Method of Adjustment using the Matrix Laboratory (MATLAB) 
and its instrument constant obtained.
