RTG – Resistance to Ground Measurements
Resistance to ground measurements indicate the surface resistance between selected locations on
a work surface and a groundable point or points. Ground points are usually in the form of snaps
installed on the material so that the material can be grounded via ground cords.
The charge dissipative rate of all ESD protective materials is related directly to electrical resistance
to ground. When making Resistance-to-Ground measurements follow this procedure:
To
GND
Connect the black test lead to the left hand jack on the meter and to ground.
Connect the white test lead to the right hand jack on the meter and to the 5-pound electrode.
Place the electrode on the material at the position specified by the procedure selected. Set
the meter to the desired voltage range. Be sure to keep the cords separated in order to
prevent false readings, especially when testing high resistance materials.
Press and hold the red test button for at least 15 - 20 seconds. The LCD expresses surface
resistance ohm values and an illuminated LED indicates the reading’s exponential value.
Repeat the procedure to measure other points on the material under test.
