DC voltage verification
To verify DC voltage:
1. Connect the calibrator output to the Model 6517B as shown in in the following figure. Ensure that
the configuration is properly grounded as noted at the beginning of this section.
Figure 135: DC voltage verification configuration
2. Turn on the Model 6517B and allow it to warm up for at least two hours before making
measurements.
3. Restore the instrument to factory default settings using the procedure described under
Considerations
(on page 16-3).
4. Select the DCV 2 V range from the front panel. Refer to "
Measurement range" on page 5-17 for
more information.

5. With zero check enabled, press
REL
to turn on the zero correct function.
See "Zero check,
relative, and zero correct" on page 5-18 for more information.
(on page 5-19)
6. Set the calibrator to 0.0 V and then turn off zero check. Allow the reading to settle completely
before continuing.
7. Press
REL
to enable the Model 6517B REL function.
8. Set the calibrator to the voltages shown in the table below.
9. Set the Model 6517B range according to the table below. Verify the reading is within the range
specified.
10. Press
REL
to turn off the REL function, and then turn zero check on. Repeat steps 4 to 9 for the
20 V and 200 V ranges.
