High Precision and Accuracy The Model 2100 features precision 10VDC accuracy of 38ppm 6½-digit resolution at a fast measurement rate of 50 readings/second (at 6½-digits) over the USB bus, a reading rate that is more than twice as fast as competitive offerings. At 4½-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. Easy to Set Up and Use The Model 2100 6½-Digit USB DMM is easy to set up and begin using right out of the box, needing no additional accessories. All units include standard USB cable, power cord, safety measurement probes, and free utility software to ensure quick startup and a lower total cost of ownership. The Model 2100’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, saving development time and cost....
