Surface Resistivity Measurements
To make surface resistivity measurements the user must also have the optional resistivity adapter
sled, Model 292/41.
The meter attaches easily to an optional resistivity adaptor sled. Parallel silicone rubber electrodes
provide for direct measurement of surface resistivity. No conversion is required with the Surface
Resistivity Test Kit. The electrode geometry is 1 square resulting in a reading expressed in
ohms/square.
 Disconnect the test leads and electrodes from the meter.
 Mount the meter securely onto the adapter sled.
 Firmly press the sled’s parallel electrodes onto the surface of the material to be tested, at the
position specified by the procedure selected.
 Press and hold the red test button for at least 15 - 20 seconds. The LCD expresses surface
resistivity in ohms/square and an illuminated LED indicates the reading’s exponential value.
