Set Up
The SRM330 has two methods to measure resistivity: Parallel
Probe Resistivity (PPR) and Probe Resistivity (CRP) method. The
PPR method uses built in probes on the back of the SRM330 and
the CRP method uses two external probes attached to the meter by
lead wires.
Parallel Probe Resistivity Method
The PRP method is used to give fast electrical resistivity measure-
ments on flat materials.
Resistance Point-To-Point
Remove all items on surface that may interfere with the test.
1. Place the meter on the surface to be tested.
2.
Move the toggle switch to “Internal”.
3. Press and hold the test button until measurement is displayed.
4. If measurement is outside acceptable limits, clean the surface
and re-test to determine if cause of failure is an insulative layer
of dirt/contamination or the surface of the material itself.
Note: Use only approved Anti-Static Mat Cleaner such as Trans-
forming Technologies StaticCare
MT
mat cleaner. Be sure the sur-
face is dry before testing.
The meter will keep updating the display while the button is held
down and will continue to display the last test reading for approxi-
mately 45 seconds after the button is released.
