*Not available in all countries

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 rang­es with superior accuracy specifications — DC
voltage from 100nV to 1kV (with 0.002% 90-day
basic accuracy) and DC resistance from 100µ
to 100M

Ω

(with 0.008% 90-day basic accuracy).

Ω

Optional switch cards enable multiplexing up to
20 different input signals for multipoint meas­urement applications.

High Throughput

The 2000 offers exceptional measurement
speed at any reso lution. 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 buf fer, making it an excel­lent 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
DC V, AC V, DCI , ACI, 2WΩ, 4WΩ, temper ature,
frequency, period, dB, dBm, continuity mea sure­ment, and diode testing. A built-in RS-232 inter­face con nects to a notebook or full-sized PC’s
serial port to take, store, process, and dis play
m e a s u r e m e n t s a u t o m a t i c a l l y .

Optional Multiplexer Cards

Creating a self-contained multipoint measure­ment solution is as simple as plugging a scanner
card into the option slot on the 2000’s back
panel. This ap proach eliminates the complexities
of triggering, timing, and processing issues and
helps reduce test time significantly. For appli­cations involving more than 10 measurement
points, the 2000 is com patible with Keithley’s
Series 7000 switch matrices and cards.
