Keithley Expands DMM Line with the 2110 Model
Keithley Instruments has unveiled a economical new offering, the Model 2110 5-1/2-digit Dual-Display Digital Multimeter is optimized for a variety of general-purpose system and bench design applications.
WhenA Rich Feature Set at a Value Price
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 4-1/2-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.
Wide Range of Applications
The Model 2110 DMM offers high value for applications in manual, semi-automatic, and automatic testing of low-cost electronic devices, circuits, modules, electrical components, and semiconductor components. Production, R&D, and test engineers, scientists, and students will find it useful for making a wide variety of measurements in the portable, bench, and system applications that don’t demand the ultra-high precision that Keithley’s other Series 2000 DMMs provide but that do require stable, accurate, and high speed measurements.
