Taking routine measurements of tiles coated with dissipative floor finish is a key
component of proper floor maintenance. Any problems that arise with the floor will be
easily detected. Keeping a record of temperature, humidity and electrical properties will
provide a reference, and will point toward a blueprint of traffic patterns on the floor. Good
record keeping will ensure success when developing and maintaining a maintenance
program.
To obtain an average measurement of a floor, map out a 4’ x 4’ section and conduct
five tests (one at a time) within the square. Conduct a test for each side of the square
and a final test diagonally through the center as shown in the drawing below.
In each RTT test, the 5
-
lb probes are placed three feet apart (36 inches). Connect the
test leads to the meter. Attach a 5
-
lb probe to the end of each lead and place three feet
apart as indicated below. Press and hold the “TEST” button on the AE -780 meter until a
value is displayed.
