DC (High resistance) Material
Description: The 16008B is designed to operate specifi-
cally with 4339B. It is used to measure surface or volume
resistance/resistivity of insulation materials. The follow-
ing figures show the block diagrams of resistivity mea-
surements.
Volume resistivity is measured across the material (MUT)
by the unguarded and guarded electrodes. Surface resistiv-
ity, on the other hand, is measured along the surface of the
MUT (between the guarded and the unguarded electrodes).
Notice that the role of the guard and unguarded electrodes
switch, when measuring volume and surface resistivity.
16008B is provided with three different electrode sizes to
meet size requirements by different measurement stan-
dards. The guarded electrode eliminates measurement
errors due to the edge effect and arbitrary contact pres-
sure can be applied to the material under test. It is also
equipped with a high-voltage protection cover to shut off
power when opened.
