Figure 39: Connections for resistivity measurements using the Model 8009 test fixture
Connect the enclosure of all metal test fixtures to protective earth (safety ground).
Nonconductive test fixtures must be rated to double the maximum capability of the test
equipment in the system. Failure to attach the ground wires to a known protective earth may
result in electric shock.
17. Use the manual
RANGE
keys to select the resistance measurement range or press the
AUTO
key to select autorange. When autorange is selected, the instrument does not go the 2
TΩ,
20
TΩ, and 200
TΩ ranges.
18. Press the
Z-CHK
key to disable zero check.
19. Press the
OPER
key to place the voltage source in operate.
20. Wait an appropriate electrification period (bias time). Typically, a bias time of 60 seconds is used.
21. Observe the resistivity reading.
22. Press the
OPER
key to place the voltage source in standby.
23. Press the
Z-CHK
key to enable zero check.
If the VOLTAGE SOURCE OPERATE LED flashes, the voltage source is current limited and the
programmed voltage is not applied to the load. If this occurs, try using a lower voltage for
the measurement.
