M8009:RSWitch?
[:SENSe[1]]:RESistance:RESistivity:M8009:RSWitch?
Query switch setting on Model 8009
Description
When using the Model 8009 Resistivity Test Fixture, the Model 6517A senses the switch setting
(Surface or Volume) of the test fixture through the safety interlock cable and automatically con-
figures the instrument for that resistivity measurement type.
This query command is used to read the switch setting (Surface or Volume) of the Model 8009
Resistivity Test Fixture.
:USER Commands
The following commands are used to configure the instrument for resistivity measurements
when using a user-supplied test fixture. These command are not needed if using the Model 8009
Resistivity Test Fixture.
:RSELect <name>
[:SENSe[1]]:RESistance:RESistivity:USER:RSELect <name>
Specify measurement type for user test fixture
Parameters
<name> = SURFace
Surface resistivity
VOLume
Volume resistivity
Query
:RSELect?
Query programmed resistivity measurement type
Description
This command is used to specify the resistivity type (SURFace or VOLume) for the user-sup-
plied test fixture. This command is not needed when using the Model 8009 test fixture.
:KSURface <NRf>
[:SENSe[1]]:RESistance:RESistivity:USER:KSURface <NRf>
Specify Ks parameter for surface resistivity
Parameters
<NRf> = 0.001 to 999.999
Ks parameter
Query
:KSURface?
Query programmed Ks parameter
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 (in mm) between the guarded electrode and the ring electrode.
See paragraph 2.7.2 (Surface Resistivity) for detailed information on surface resistivity mea-
surements.
