18-16 Performance Verification
5. Verify resistance measurement accuracy for the 2kΩ-20MΩ ranges as listed in Table
18-5. For each test point:
• Select the correct Model 6514 measurement range.
• Set the calibrator resistance to the indicated value.
• If the calibrator resistance differs from the nominal value, recalculate new reading
limits based on the resistance and Model 6514 accuracy specifications.
•Verify that Model 6514 resistance reading is within the required reading limits.

Reading limits based on Model 6514 accuracy specifications and nominal resistance values. If
actual resistance values differ from nominal values shown, recalculate reading limits using
actual calibrator resistance values and Model 6514 one-year accuracy specifications.
