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 7½-digit 2001 and 8½-digit 2002 High Performance Digital Multimeters not only deliver performance specifications usually associated with instruments that cost thousands more, but they also offer a broad range of functions not typically available from DMMs. The 2002 is based on the same superior measurement technology as the 2001, and the front panels of both instruments have the same look, feel, and response.
Key Features
• True 7½- (2001) or 8½-digit (2002) resolution
• Exceptional measurement integrity with high speed
• High speed function and range changing
• Broad range of built-in measurement functions
• Multiple measurement display
• Built-in 10 channel scanner option
• GPIB interface • HP3458A emulation mode (2002)

Benefits |
True 7½-digit resolution based on 28-bit A/D converter | Provides greater dynamic range, avoiding range-shift errors and delays |
Exceptional measurement integrity combined with high throughput |
Tests precision components quickly and accurately in production environments |
Advanced AC measurements including Peak ACV, AC or AC+DC Coupling, RMS or average, and low frequency RMS | Reduces the number of instruments in your test system |
Multiple measurement display | Displays multiple measurements such as DC and AC volts and the AC frequency from a single measurement connection simultaneously, reducing the need for additional instruments |
Optional plug-in switch cards for multipoint measurements | Simplify creating a self-contained, multipoint switch and measure solution |
Built-in bar graph display | Tracks reading trends around a target value saving time from off-line measurement analysis |
True 7½- (or 8½-) Digit Resolution While other DMMs may claim 7½- or 8½-digit resolution, they 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 1 µV to 20 V on a single range, thus avoiding range-shift errors and delays. Built-In Scanner (Multiplexer) Options With the addition of a plug-in scanner card, the 2001 or 2002 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.
