2000
6½-Digit Multimeter
The Model 2000 6½-Digit Multimeter is part of
Keithley’s family of high performance DMMs .
Based on the same high speed, low noise A/D
converter technology as the Model 2001 and
2002, the 2000 is a fast, accurate, and highly
stable instrument that’s as easy to operate as it is
to afford . It combines broad measurement rang-
es with superior accuracy specifications — DC
voltage from 100nV to 1kV (with 0 .002% 90-day
basic accuracy) and DC resistance from 100µ
W
to 100M
W
(with 0 .008% 90-day basic accuracy) .
Optional switch cards enable multiplexing up to
20 different input signals for multipoint meas-
urement applications .
High Throughput
The 2000 offers exceptional measurement
speed at any resolution . At 6½ digits, it delivers
50 triggered rdgs/s over the IEEE-488 bus . At
4½ digits, it can read up to 2000 rdgs/s into its
internal 1024 reading buffer, making it an excel-
lent choice for applications where throughput is
critical .
For benchtop or stand-alone applications, the
2000 has a front panel design that’s simple
to understand and easy to use . The 2000 has
13 built-in measurement functions, including
DCV, ACV, DCI, ACI, 2WW, 4WW, temperature,
frequency, period, dB, dBm, continuity measure-
ment, and diode testing . A built-in RS-232 inter-
face connects to a notebook or full-sized PC’s
serial port to take, store, process, and display
measurements automatically .

optional Multiplexer Cards
Creating a self-contained multipoint measure-
ment solution is as simple as plugging a scanner
card into the option slot on the 2000’s back
panel . This approach eliminates the complexities
of triggering, timing, and processing issues and
helps reduce test time significantly . For appli-
cations involving more than 10 measurement
points, the 2000 is compatible with Keithley’s
Series 7000 switch matrices and cards .
