only deliver performance specifications usually associated only with instruments that cost thousands more, but they also offer a broad range of functions not typically available from DMMs.
True 71⁄2- (or 81⁄2-) Digit Resolution
While other DMMs may claim 71⁄2- or 81⁄2-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 resolution 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 Model 2001 and
2002 provide more than 2000 readings per second at 4

up to 44/second on DCV and ohms.
The Model 2002 uses a unique single-phase method for 4-wire ohms measurements. 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 production test problems.
High Accuracy ACV Measurements
A patented circuit design makes the 2001 and
2002’s AC measurements several times more
accurate 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 measurement capability for a wide variety
of applications.
