General Guidelines for Testing
 Use both 5-pound electrodes for RTT (Resistance between two points) testing.
 Use one 5-pound electrode and one lead to a groundable point for RTG (Resistance to
Ground) testing.
 Use the optional resistivity adapter sled (removing leads and electrodes) for Resistivity
measurements.
 Make sure that the item being measured is electrically isolated (i.e. placed on an insulative
surface) as the meter will measure the lower resistance path.
 Make sure that the test leads are separated or the meter may measure the lower resistance
path
 When using the 5-pound electrodes:
o Place the electrodes no closer than 2 inches from edge of surface being measured.
o Place the electrodes no closer than 3 inches to any groundable point
o Preferred placements include: most commonly used surface portion, most worn,
center, and furthest from a groundable point.
o For RTG, connect the sensing lead with shielded plug to the groundable point.
 If the surface has sections (like tile flooring or garment panels), for RTT place the electrodes
on different sections.
