Direct Current Sheet Resistance Probe Design

      Disclosed is a reliable direct current sheet resistance
measurement probe which is especially suitable for machine frame
conductive paint resistance measurements.

      As shown in the figure, the probe assembly includes four major
parts.

      The first part is made up of two electrodes with probe tips.
The double electrode probe is fabricated from gold-plated rectangular
copper electrodes in parallel to each other.  The contacting base
surface of the electrodes are flat and smooth.

      The second part is a pair of wires attached between the
electrodes and a DC ohmmeter.  Detachable wires with plugs may be
used to provide for point-to-point measurements.  The ohmmeter
measures ohms per square unit of measure, and the readings are
independent of probe size.

      The third part is a spring-loaded insulating holder. Tension of
the spring is adjustable, and a scale is used to depict the amount of
this force.

      The fourth part is made up of magnets placed at the bottom of
the holder housing.  This will hold the probe in position during
measurement and data recording.
