Attach the PM5s mounting bracket to a non-conductive pole to aid with potential free measurements. Potential free (ungrounded) AC Electric Field measurements are influenced by the conductive interference of the human body. The use of a non-conductive Measuring Rod creates distance between between meter operator and the measuring area and which eliminates this interference. A distance of 3 to 5 feet is recommended.
