-digit resolution, those instruments
must average multiple readings to extend their resolution. The resolution
specifications of the 2001 and 2002 are based on a 28-bit A/D converter that
provides the resolution needed to discern smaller changes. This higher reso-
lution also provides greater dynamic range, making it possible to measure
from 1μV to 20V on a single range, thus avoiding range-shift errors and delays.
High Throughput, High Accuracy DCV and
Resistance Measurements
In applications where high throughput is critical, both the 2001 and 2002 pro-
vide more than 2000 readings per second at 4

-digit resolution. At 7

digits,
the 2002 maintains full rated accuracy at reading rates up to 44/second on
DCV and ohms.
The Model 2002 uses a unique single-phase method for 4-wire ohms measure-
ments. This makes it twice as fast for a given power line cycle rate. This also
eliminates errors due to changing lead resistances that can result from fast test
handlers. A built-in “open-lead” detection circuit also eliminates many produc-
tion test problems.
High Accuracy ACV Measurements
A patented circuit design makes the 2001 and
2002’s AC measurements several times more accu-
rate than competitive DMMs, thus maintaining
very good accuracy (better than 0.1%) down to
1Hz. The wide bandwidth of these DMMs allows
for accurate measurements of high frequency AC
signals without the need for a special AC meter.
Both the 2001 and 2002 feature TRMS AC, Average
AC, Peak AC, AC+DC, and Crest Factor measure-
ment capability for a wide variety of applications.
Built-In Scanner (Multiplexer)
Options
With the addition of a plug-in scanner card, it
becomes a complete scan and measure system for
applications involving up to ten measurement points. The additional resolution and measurement ranges
provided by the 2002 make it an excellent choice for production test, design verification, and metrology
applications where high accuracy is critical.
