6. Configure the DMM to the low voltage value, as defined in Table 3.
7. Enable the calibrator to source the high voltage value, as defined in
Table 3.
8. Allow the DMM and calibrator to settle before taking a measurement. NI
recommends a settling time of 10 seconds.
Note
A settling time of 10 seconds accommodates any changes to range,
polarity, and thermal EMF effects that increase the base settling time.
9. Take the measurement with the DMM.

.
a. Use the high voltage value as the reference voltage signal, as
defined in Table 3.
b. Use the low voltage value as the measured voltage signal, as
defined in Table 3.
Repeat 4 times, once for each channel.
Repeat 1 time, once for each set of voltage values.

11. Configure the DMM to measure the low voltage value, as defined in
Table 4.
12. Configure the calibrator to the high voltage value, as defined in Table 4.
13. Enable the calibrator to source the high voltage value.
14. Allow the DMM and calibrator to settle before taking a measurement. NI
recommends a settling time of 10 seconds.
