-- Test & Measurement World, 6/1/2008
The SMU2055 from Signametrics lets you add a DMM to any Windows PC through a USB port. The SMU2055 measures DC and true-RMS AC voltage and current. It also measures resistance (two wire and four wire) and performs diode tests. It can measure at 250 readings/s with 6½-digit resolution that provides 2.4 million counts.
You can operate the SMU2055 through a soft front panel (included), or you can write your own application with almost any Windows-based language. Software support includes Excel, LabView, LabWindows/CVI, Matlab, Microsoft .NET, Vee, and Visual Basic. You can write applications for production and engineering measurements, or you can use the instrument for portable applications. With the soft front panel, you can select measurement type, range, and measurement rate, and you can view measurements. The bus-powered SMU2055 consumes 1.5 W, measures 5x7x1.3 in., and weighs 8 oz.
