A-2 Specifications
Specifications
The following pages contain the complete specifications for the 2002.
Every effort has been made to make these specifications complete by charac-
terizing its performance under the variety of conditions often encountered in
production, engineering, and research.
The 2002 provides Transfer, 24-hour, 90-day, 1-year, and 2-year specifica-
tions, with full specifications for the 90-day, 1-year, and 2-year intervals. This
allows the operator to utilize 90-day, 1-year, or 2-year recommended calibra-
tion intervals, depending upon the level of accuracy desired. As a general rule,
the 2002’s 2-year performance exceeds a 6
½
-digit DMM’s 90-day, 180-day, or
1-year specifications.
Absolute Accuracy
All DC specifications are given as relative accuracies. To obtain absolute
accuracies, the absolute uncertainties of the calibration sources must be
added to the relative accuracies. The absolute uncertainties for the calibration
sources used during Keithley’s factory calibration are included in the specifi-
cations. The uncertainties of the operator’s sources may be different.
All AC specifications are given as absolute accuracies.
Typical Accuracies
Accuracy can be specified as typical or warranted. All specifications
shown are warranted unless specifically noted. Almost 99% of the 2002’s
specifications are warranted specifications. In some cases it is not possible to
obtain sources to maintain traceability on the performance of every unit in
production on some measurement (e.g., high-voltage, high frequency signal
sources with sufficient accuracy do not exist). These values are listed as
typical.
