:KSURface <NRf>
This command is used to specify the Ks parameter for surface resistivity.
Usage
[:SENSe[1]]:RESistance:RESistivity:USER:KSURface <NRf>
:KSURface?
<NRf>
 0.001 to 999.999: Ks parameter
Details
Description This command is used to specify the Ks parameter for surface resistivity measurements
when using a user-supplied test fixture. This command is not needed when using the Model 8009 test
fixture.
The Ks parameter is calculated as follows:
Ks = P/g
Where: P = Effective perimeter (in mm) of the guarded electrode
g = Distance (mm) between the guarded electrode and the ring electrode

None
:KVOLume <NRf>
This command is used to specify the Kv parameter for volume resistivity.
Usage
[:SENSe[1]]:RESistance:RESistivity:USER:KVOLume <NRf>
:KVOLume?
<NRf>
 0.001 to 999.999: Kv parameter
Details
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.

None
:SOURce subsystem
This subsystem is used to set the logic level (true or false) of each digital output line, and is used to
configure the V-source. Note that the V-source is controlled (standby/operate) from the :OUTput1
subsystem.
The commands for this subsystem are summarized in the :SOURce command summary (on page 14-
20).
