DIGITAL MULTIMETERS & SYSTEMS
6½-Digit USB Digital Multimeter
The Model 2100 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 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
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 6½-digit DMM
for critical measurements at a
5½-digit price
• 11 measurement functions
cover most commonly measured
parameters
• Fully specified accuracies on
all functions for ISO-compliant
results
• Included PC software utilities
for graphing and data sharing in
both Microsoft® Word and Excel
High Precision, Low Cost
The Model 2100 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 10kΩ
range. At 6½ digits, the Model 2100 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 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: 100Ω, 1kΩ, 10kΩ, 100kΩ, 1MΩ, 10MΩ, and 100MΩ
• Frequency: From 3Hz to 300kHz
• Rugged construction for
durability in bench/portable
applications
• Period measurement
• Selectable front/rear inputs
facilitate bench or rack use
• Programmable A-D converter and filter settings for signal to noise optimization
• Includes all accessories, such
as startup software, USB cable,
power cable, and safety test
lead, for lowest total cost
• CE compliant and UL listed
• TMC compliant USB 2.0
interface for use with SCPI
test programs
• Diode measurement
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 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 has the durability to withstand
bench, portable, or stacking applications. A sturdy carrying handle facilitates transportability.

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.
