In summary, the Keithley 2002 is an 8.5-digit high-performance digital multimeter that delivers metrology-class accuracy at a fraction of the price of comparable instruments. It is based on the same measurement technology as the 7.5-digit 2001, but extends resolution and accuracy specifications for production test, design verification, and metrology applications where the highest accuracy is critical.
The 2002 is used in calibration laboratories, metrology benches, and high-end production test where the resolution and accuracy of an 8.5-digit DMM are required. Common applications include DCV transfer measurements against standard cells, precision resistor characterization, low-frequency AC measurement, and any application where the measurement floor is set by the DMM's own noise and accuracy.
The 2002 uses a single-phase technique for 4-wire ohms measurement, which is twice as fast for a given power-line cycle rate as conventional DMMs. It also eliminates errors caused by changing lead resistance from fast test handlers, and includes built-in open-lead detection that eliminates many production-test problems.
| Specification | Value |
|---|---|
| 200 mV range, 24-hour transfer | ±(3.5 ppm rdg + 3 ppm rng) |
| 2 V range, 24-hour transfer | ±(1.2 ppm rdg + 0.3 ppm rng) |
| 20 V range, 24-hour transfer | ±(1.2 ppm rdg + 0.1 ppm rng) |
| 200 V range, 24-hour transfer | ±(5 ppm rdg + 0.4 ppm rng) |
| 1000 V range, 24-hour transfer | ±(5 ppm rdg + 0.08 ppm rng) |
| Input resistance | >100 GΩ (200 mV to 20 V) |
The 2002 sits in the same metrology tier as the HP/Agilent 3458A and is the standard 8.5-digit Keithley DMM in calibration laboratories. The 3458A emulation mode allows the 2002 to drop into existing 3458A-controlled metrology systems with minimal code change.
Standard accessory packages ship where applicable. Unnecessary accessories may not be included on this Pre-Owned unit; contact a Test Architect to confirm anything specific your application requires.
Like the 2001, the 2002 uses a 28-bit A/D and a patented AC measurement circuit that bypasses the prime error-contributing section of conventional RMS converters. The 2002 extends the 2001's resolution by an extra digit, sharpens 4-wire ohms speed and accuracy, and adds support for SPRTs (Standard Platinum Resistance Thermometers) to ITS-90 in addition to thermocouples and 100 Ω platinum RTDs.

The 2002 accepts the same optional plug-in scanner cards as the 2001 (2000-SCAN, 2001-SCAN, 2001-TCSCAN). The scanner card converts the 2002 into a complete scan-and-measure system for up to 10 channels.
