Description
Keithley 2002
DMM users whose applications demand exceptional resolution, accuracy, and sensitivity combined with high throughput now have two attractive alternatives to high priced, high-end DMMs. Keithley’s 71⁄2-digit Model 2001 and 81⁄2-digit Model 2002 High Performance Digital Multimeters not 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 41⁄2-digit resolution.
At 71⁄2 digits, the Model 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 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.
