RTT – point-to-point resistance
RTT denotes a point-to-point resistance measurement between two locations on the surface of a material or system under test.
What RTT is used for
It helps verify electrical continuity and the properties of the area between two measurement points, for example on an ESD bench, mat or floor. Unlike RTG, it does not measure a path to ground. Method, electrodes and conditions affect the result.
Compare with RTG.
