Keithley 2100/120 - 6.5 Digit USB Digital Multimeter (120V)

The Model 2100/120 USB Digital Multimeter is the newest member of Keithley’s family of high performance DMMs. Its high accuracy (38ppm), 6½-digit resolution is ideal for critical measurements. The Model 2100/120 features 11 measurement functions and 8 math functions to easily accommodate the most commonly measured parameters. All accessories, such as USB cable, probes, and software, are included with the Model 2100. With its unique combination of high precision and low total cost of ownership, the Model 2100/120 is an unbeatable value for R&D engineers, test engineers, scientists, and students making basic precision measurements on the bench and in system applications.

High Precision, Low Cost

The Model 2100/120 provides stability, accuracy, and speed at a very low cost. It has 0.0038% 1-year basic DC voltage accuracy on the 10V range and 0.013% 1-year basic resistance accuracy on the 10kW range. At 6½ digits, the Model 2100/120 delivers 50 triggered rdgs/s via the USB remote interface. At the fast 4½ digit setting, it reads over 2000 rdgs/s into its 2000 reading internal buffer.

The Model 2100/120 provides a wide number of measurement ranges and functions:

• DC voltage: 0.1V, 1V, 10V, 100V, and 1000V 
• AC voltage: 0.1V, 1V, 10V, 100V, and 750V 
• DC current: 10mA, 100mA, 1A, and 3A 
• AC current: 1A and 3A 
• Two- and four-wire resistance: 100W, 1kW, 10kW, 100kW, 1MW, 10MW, and 100MW 
• Frequency: From 3Hz to 300kHz 
• Period measurement 
• Diode measurement 
• Programmable A-D converter and filter settings for signal to noise optimization

Additionally, eight mathematical operations can be performed on measurement readings: RATIO, %, Min/Max, NULL, Limits, mX+b, dB, and dBm testing. Microsoft Office, Word, and Excel add-in tools allow remote storage and recall of the measured values from these applications. A graphing utility enables charting of measurements versus time for trending and noise observations.

The TMC compliant USB remote interface enables control from a PC for consistent test/calibration procedure execution and easy re-use of existing SCPI programs, including Agilent Model 34401A command emulation.

Simple to Use

The Model 2100/120 can be setup quickly and is very easy to use. It has a high contrast front panel and keypad that are intuitive and user-friendly. An easy to read 5×7 dot matrix, vacuum fluorescent display (VFD) offers three-color annunciators so users can easily distinguish each function symbol by its color.

Strength and Versatility

With its rugged construction and rubber bumpers, the Model 2100/120 has the durability to withstand bench, portable, or stacking applications. A sturdy carrying handle facilitates transportability.

Applications

• Test Engineers: Manual and semi-automatic electrical functional test 
• Development Engineers: Electrical/electronic circuit and product validation 
• Service/Calibration Technicians: Electronic product repair and calibration 
• Research Scientists: Electrical and physics experiments testing 
• Engineering Students: Electronic device and circuits experiment testing

Startup Software, PC Utilities Included

The KI-Tool application provides charting and graphing capabilities without programming to simplify setup, checkout, and basic measurement applications requiring graphical data representation. Scale, offset, and level can be adjusted to fine tune images for visual evaluation of signal and noise elements over time. It also includes tabular data and SCPI command prompt windows for maximum flexibility. Data sets can also be saved to disk files.

The Microsoft Excel Add-In utility is also included and provides quick data import into a standard Microsoft Excel spreadsheet, including selectable graphing, instrument settings, and number of data points collected. Data can then be analyzed through standard or optional Microsoft Excel functions, including graphical, statistical, and trend charting. A version supporting Microsoft Word is also included for direct data import into reports.
