2002 Multimeter
Specifications
The following pages contain the complete specifications for the 2002.
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 2002 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 2002’s 2-year performance exceeds a 6½-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 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 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 measurements (e.g., high-voltage, high-frequency signal
sources with sufficient accuracy do not exist). These values are listed as
typical.

Factory calibration uncertainty represents traceability to
NIST. This uncertainty is added to relative accuracy
specifications to obtain absolute accuracies. The 200mV and
2V range uncertainties are equal to the uncertainty of the 2V
calibration source. The 20V, 200V, and 1000V range
uncertainties are equal to the uncertainty of the 20V
calibration source.

Polarity Reversal Error This is the portion of the instrument error that is seen when
HI and LO are reversed. This is not an additional error—it is
included in the overall instrument accuracy specification.
Reversal Error: <4 counts at 10V input at 7½ digits, 10 power

filter.
Input Bias Current <100pA at 25°C.
Settling Characteristics <50µs to 10ppm of step size for the 200mV–20V ranges. <1ms
to 10ppm of step size for the 200V and 1000V ranges. Reading
settling times are affected by source impedance and cable
dielectric absorption characteristics.
Autoranging Autoranges up at 105% of range, down at 10% of range.
