Abstract
A hand truck like frame has a pair of wheels, each of which is coated with an electrically conductive material so that in a selected operating mode the wheels define electrodes. A separate pair of electrodes is mounted to the frame and the electrodes and the wheels are electrically connected through switching circuits to an ohmmeter. The ESD potential between the electrodes and/or the wheels may be measured in several selected modes for point to point, point to ground and point to bench top measurements.
