The surface resistance meter uses precision spaced parallel bars positioned
on the back for sensing surface resistivity.
For Surface Resistivity Readings:Place the meter on the
surface being tested and press the test button. If the 10^6 LED is illuminated,
the surface being tested has a surface resistivity of 10^6 ohms per square or
less. If the LED labeled insulative, is illuminated, the surface under test has
a surface resistivity that is greater than 10^12 ohms per square. (Be sure the
ground wire is not connected through the ground jack when taking surface
For Resistance to Ground Readings:
Place the meter on the surface being tested. Connect the meter to a known ground
through the ground jack. When the ground wire is connected through the ground
jack, the meter will not measure surface resistivity. Press the center button
and the illuminated LED will indicate the resistance 10^5 ohms or less. If the
LED shows insulative ,the resistance to ground of the surface under test is
greater than 10^12 ohms.
