MODEL 09-0102: 2-POINT PEN PROBE
Point-to-Point Resistance Measurement for Materials
Introduction:
Point-to-point resistance measurements for planar
material characterize the ability of a planar (flat) sample to
conduct electricity and electrostatic charge from one point
to another along the top-most layer of the material. For
thick samples with bulk conductivity, the resultant reading
can come from many paths of current flows, as shown
below. (Courtesy Ben Baumgartner, ESDicovery 2000)
This test is designed to check for hot spots on a sample of
a finish product where the NFPA probes (5lbs weights) are
too large to detect or to fit on the sample.
Procedures:
1. Place sample to be tested on an insulative
platform such as plastic or acrylic plate.
