:KVOLume?
Query programmed Kv parameter
Description
This command is used to specify the Kv parameter for volume resistivity measurements when
using a user-supplied test fixture. This command is not needed when using the Model 8009 test
fixture.
Kv is the effective area of the guarded electrode for the particular electrode arrangement em-
ployed and is calculated as follows:
Note: The following calculation assumes that the effective area coefficient (B) is zero, which is
typically used for volume resistivity.
where: D1 = Outside diameter of guarded electrode.
If using a different value for B, use the calculation shown in paragraph 2.7.2 (Volume Resistivity).
