RTT - Measuring Resistance Between Two Points
Point to point surface resistance measurements are made using the meter with both of the 5-pound
weight electrodes. This test determines the resistance two points independent of a ground point.
To perform surface resistance tests you must first determine what test procedure to use. The test
procedure helps you determine the proper preparation of the material to be tested and the spacing of
the weights. Once the testing parameters are determined proceed with set up for point-to-point
testing.
 Connect the test leads to the meter and the 5-pound electrodes in a set up similar to the one
shown above.
 Place both electrodes on the material at positions determined by the procedure selected. Set
the meter to the required test voltage as specified in the test procedure and the resistance of
the material.
 Press and hold the red test button for at least 15 - 20 seconds. The LCD expresses surface
resistance ohm values and an illuminated LED indicates the reading’s exponential value.
