Keithley Instruments announces the release of the Model 2100 6 1/2-Digit USB Digital Multimeter (DMM), a USB-based instrument. The Model is usefull for a range of production test, burn-in, and manual and semi-automatic R&D applications in bench, portable, or small system measurement configurations. The device features precision 10VDC accuracy of 38ppm 6 1/2-digit resolution at a fast measurement rate of 50 readings/second (at 6 1/2-digits) over the USB bus, a reading rate that is more than twice as fast as competitive offerings. At 4 1/2-digits, the Model 2100 reads more than 2000 readings/second into its internal, 2000-reading data buffer.

Eleven measurement functions cover the most commonly measured parameters, including Volts, Ohms, Amps, and RTD temperature measurement capability, as well as MX+B, dB, and dBm math modifiers. Fully specified accuracies are valid for one year on all functions for ISO-compliant applications and facilities. The Model 2100 also offers selectable front and rear inputs plus two- and four-wire remote sense resistance inputs that facilitate use as both a stand-alone, benchtop DMM or in small systems applications. All units include standard USB cable, power cord, safety measurement probes, and free utility software.

The Model's USB interface supports the TMC (Test and Measurement Class) protocol, allowing SCPI (Standard Commands for Programmable Instrumentation) commands to be sent over the USB bus for added data transfer and control options. This TMC-compliant USB interface ensures preservation of existing SCPI test code. 2100 includes KI-Tool, a built-in graphic utility that enables trend plotting and data transfer to a PC. It also includes an add-in tool that is used for importing data directly into Microsoft(R) Excel and Word documents. USB drivers are also provided with each Model 2100 DMM. The rugged and durable construction of the DMM, including a heavy gauge chassis and cover and rubberized front and rear bumpers, makes it suitable for bench applications as well as portable and field applications.

Price and Availability

Keithley's Model 2100 6 1/2-Digit USB DMM is available for an introductory price of $795 USD through September 30, 2007. After that time, the list price will be $845.
