General resistivity measurement procedure
The following steps summarize the basic steps to measure resistivity when a Model 8009 test fixture
is used.
If the 6517B is already configured to use the Model 8009 Resistivity Test Fixture, the interlock cable
must be connected to the 8009 test fixture. The measurement type (surface or volume) is selected
by the switch position on the test fixture. Attempts to change the measurement type from the 6517B
menu are ignored. If the interlock cable is not connected, the settings for volume or surface do not
work properly and you cannot change the measurement type from the menu.
Hazardous voltages may be present on the output and guard terminals. To prevent electrical
shock that could cause injury or death, NEVER make or break connections to the 6517B while
the output is on. Power off the equipment from the front panel or disconnect the main power
cord from the rear of the 6517B before handling cables connected to the outputs. Putting the
equipment in standby mode does not guarantee that the outputs are not powered if a
hardware or software fault occurs.
