Economical, programmable 5½-Digit Digital Multimeter

18 September 2012 - Keithley Instruments expands its digital multimeter (DMM) product line with an economical new offering. The Model 2110 5½-digit Dual-Display Digital Multimeter is optimized for a variety of general-purpose system and bench design applications. When compared with leading 5½-digit DMMs, the Model 2110 offers superior throughput (up to 10x faster), accuracy (up to 2x better DC voltage accuracy), a lower purchase price, and greater integration flexibility.

System features such as external triggering, a built-in reading buffer, and an optional GPIB interface enhance ease of use. The Model 2110's capabilities include DC voltage (up to 1000V) and current (up to 10A), AC voltage (up to 750V) and current (up to 10A), two- and four-wire resistance (up to 100 mega-ohms), temperature, frequency (10Hz–300kHz) and period, and capacitance (1 nanofarad to 100 microfarad ranges) measurements. A variety of mathematical functions and diode and continuity test functions are also included. Programmable A-D converter and filter settings simplify optimizing the Model 2110's signal-to-noise ratio to improve measurement accuracy. At the fast 4½-digit setting, it takes up to 50,000 readings/second.

The instrument's dual display can show the results from two measurements simultaneously, such as DC voltage and temperature, so users can monitor temperature fluctuations without interrupting other measurements. Its intuitive front panel makes it easy enough for students to use without sacrificing measurement performance or flexibility.

Temperature Measurement Support

Temperature is the most commonly measured parameter, and the Model 2110 includes support for making temperature measurements with RTDs, NTC thermistors, and B, C, E, J, K, N, R, S and T-type thermocouples. A built-in cold junction compensator ensures higher thermocouple measurement accuracy without the need for additional plug-ins.

Built-in Mathematical Functions and Included Test Tools

To simplify the process of converting raw measurement data into usable information, the Model 2110 includes the most often-used mathematical functions: percentage, average, min/max, null, limits, mX+B, dB, and dBm. The KI-Tool and KI-Link software tools included help users to control the instrument remotely, record measurements, and display time-series plots of the results, then import them into either Microsoft Word or Excel files for creating reports. LabVIEW and IVI drivers provide further programming flexibility.

Remote Interfaces

With USB-only or USB/GPIB control options, the Model 2110 is simple to integrate into test systems with other instruments, such as Keithley's growing line of Series 2200 DC Power Supplies. The TMC-compliant USB remote interface and the optional GPIB interface allow easy re-use of existing SCPI programs.

Pricing and Availability

The U.S. list price of the Model 2110 5½-Digit Dual-Display DMM is $595 for the USB-only version and $725 for the USB/GPIB option, with sales beginning immediately. Units will ship from stock or within two weeks ARO. The instrument includes a one-year factory warranty and three- and five-year extended warranties are available.
