Specifications
The following pages contain the condensed specifications for the 2010. Every effort has
been made to make these specifications complete by characterizing its performance under the
variety of conditions often encountered in production, engineering, and research.
The 2010 provides transfer, 24-hour, 90-day, 1-year, and 2-year specifications, 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 calibration intervals, depending upon the level of
accuracy desired. As a general rule, the 2010's 2-year performance exceeds a 6
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 specifications. 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 2010's specifications are warranted specifica-
tions. In some cases it is not possible to obtain sources to maintain traceability on the perfor-
mance of every unit in production on some measurements (e.g., high-voltage, high-frequency
signal sources with sufficient accuracy do not exist). These values are listed as typical.
