Resistivity measurements
NOTE The following procedure to measure resistivity (surface or volume) requires the
use of the Keithley Model 8009 Resistivity Test Fixture. Refer to the Model 8009
Instruction Manual for details on using the test fixture.
The following procedure requires “BENCH” reset conditions. See “Bench defaults” to
reset the instrument.
1. With zero check enabled (“ZeroCheck” displayed), select the ohms function by
pressing R.
2. Select Auto V-Source ohms. In this mode, the V-Source is automatically set to a
voltage (nominally 40V or 400V) that optimizes measurement accuracy. See “Auto
V-Source” located under “Resistance Measurements” to select Auto V-Source
ohms.
NOTE “BENCH” reset conditions selects Manual V-Source ohms. In this mode, you
must manually set the V-Source level for the measurement. See “Voltage Source”
for details on using the V-Source.
WARNING Selecting Auto V-Source ohms may set the V-Source to 400V.
3. Select a measurement range or use autoranging:
a. To automatically select the most sensitive range, enable autorange. The AUTO
key enables and disables autorange. When enabled, the AUTO annunciator is
on.
b. For manual ranging, use the RANGE
and keys to select a measurement
range consistent with the expected resistance.
4. Connect the Model 6517A to the Model 8009 test fixture as shown in Figure 1-6,
and set the switch on the test fixture to the desired measurement type (Surface or
Volume).
5. Select the resistivity measurement mode as follows:
a. Press the CONFIG and then R to display the ohms configuration menu.
b. Use the and keys to place the cursor (blinking menu item) on MEAS-
TYPE and press ENTER.
c. Place the cursor on RESISTIVITY and press ENTER.
NOTE The Model 6517A senses the switch position (surface or volume) on the Model
8009 through the interlock cable, and automatically configures the instrument
for that measurement type.
