2. Select the 2 TΩ range on the Model 6517B.
3. Place the voltage source in operate.
4. Make sure that zero check is disabled and allow the reading to settle.
5. Verify that the displayed reading is within the calculated limits listed in the "Limits for ohms
verification" table.
6. Repeat steps 2 through 5 for the 20 TΩ and 200 TΩ ranges.
7. Turn off the voltage source, then disconnect the standard resistor from the Model 6517B.
