The Keithley 2002 8 1/2-Digit High-Performance Digital Multimeter w/8K Memory not only delivers performance specifications usually associated with instruments that cost thousands more, but it also offers a broad range of functions that are not typically available from DMMs.

True 8 1/2-Digit Resolution

The resolution specifications of the 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.

Built-In Scanner (Multiplexer) Options

With the addition of a plug-in scanner card, the 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.

High Accuracy ACV Measurements

A patented circuit design makes the 2002 AC measurements several times more accurate than competitive DMMs. In this circuit, the signal bypasses the prime error-contributing section of conventional rms converters. This increases the accuracy at almost any voltage level, and also increases sensitivity down to a guaranteed 1% of the selected range, compared to 5–10% for most other DMMs. The result is highly accurate measurements over a broad range of inputs.

Applications involving vibration, servo, guidance, shock, and control systems often require accurate low frequency ACV measurements. The 2002 maintains 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. The 2002 features TRMS AC, average AC, peak AC, AC+DC, and crest factor measurement capability for a wide variety of applications.

High Speed for High Throughput

In applications where high throughput is critical, the 2002 provides more than 2000 readings per second at 4 1/2-digit resolution.

Fast, Flexible Triggering

Trigger latency - the delay between trigger and measurement - is often a barrier to higher throughput. Also, variability in latency can complicate predicting measurement timing. The 2002 trigger is less than 2μs+/-1μs, which is much faster than typical system DMMs.

The unique Trigger-Link feature included in the Model 2002 can be used to coordinate the operation of two or more instruments. Trigger-Link combines six independent software selectable trigger lines on a single connector for simple, direct control over all instruments in a system.

Spot Trends with the Bar-Graph Display

The ability to track reading trends around a target value easily can be just as important as the absolute readings. A unique bar-graph display function in the 2002 indicates data as a percentage of the selected range from +/-0.01% to +/-100%. Whether adjusting about zero or any other desired value, this display can replace a nulling differential voltmeter.

Capture Spikes Down to 1μs

The 2002 and has internal peak detectors that can catch 1μs spikes such as power supply spikes and transients, AC line power surges, and short-duration dropouts on components. These peak detectors operate up to 1 MHz for repetitive signals or down to 1μs for single spikes, so there is no need for a separate scope. The DMMs can automatically display and store the highest value or display the maximum and minimum values of spikes.

Built-in Features and Capabilities

The 2002 offers many built-in measurements that are typically unavailable in instruments of this type, including in-circuit current, temperature with thermocouples or RTDs, and peak spikes. Four separate outputs linked to limits simplify configuring the DMMs for use in binning operations.

The built-in AC crest factor measurement helps ensure the accuracy of AC measurements. Other DMMs typically perform AC measurements for signals without excessive crest factor - the ratio of peak value to rms values. However, when crest factor rises, measurements may not meet specs. With a 2002, there is no need for an oscilloscope to determine if the crest factor is acceptable - the DMM measures it directly.

While some DMMs calculate average AC from the rms value, these calculations apply only to sine wave inputs. The 2002 measures peak value, average and true rms directly to obtain a complete characterization of the signal. This capability makes these DMMs ideal for AC circuit design or test applications and for verifying test voltages specified only in averages.

When measuring AC or digital signals, frequency is critical. The 2002 accurately measures frequency up to 15 MHz. Accurate triggering on the signal is critical to measure frequency reliably. The frequency counters in the 2002 have a fully adjustable trigger level for good measurements of noisy signals.

Multiple Measurement Display

The 2002 can display DC and AC volts and the AC frequency from a single measurement connection simultaneously. Several other multiple-measurement displays are available, including crest factor and bar graph. By measuring sequentially and displaying simultaneously, the 2002 operates as if three different meters are working together.

Option Slot Extends DMM Performance

An option slot in the back of the 2002 opens the door to a wide range of measurement capabilities. Choose a 10-channel general-purpose scanner card or a 9-channel thermocouple scanner card to make measurements on multiple test points or devices. This can eliminate the need for a separate scanner and significantly reduce programming and setup time.
