CALIBRATION
Note that typically, calibration adjustment involves the use of pre-
cise devices of electrical signal sources that evaluate the perform-
ance of key properties for other devices called units under test
(UUT). Because these precise devices have thoroughly known
performance characteristics compared to the UUT, it is possible to
use these devices to identify or minimize errors in performance
evaluation and/or calibration adjustment of the UUT. Generally,
the performance of such precision devices is four or more times
better than the UUT. Usually, these electrical signal sources are
often referred to as calibrators. For an example, the DC voltage
uncertainty specification of the Fluke 5720A and Fluke 5730A can
meet the calibration for the DC voltage meter up to 6½ digits.
