A measurement study gets performed using the Falling Method of potential or of 62%, which requires a spade terrometer with valid calibration in which the ohmic resistance measurements is done.
A photographic report is delivered and it has to contain this information:
Measurement equipment used description.
Measurement method description.
Record of the measured values of the ohmic resistance with photographs.
Record of the continuity in connection points to ground.
Conclusions about fulfilment of the norm and recommendations.
Measurement protocol signed by client’s staff.
Copy of the calibration certified of used equipment.
