True 6-½ digit USB DMMs
While most 6-½ digit DMM's are limited to around 1,000,000 A/D counts, the SMU2055 sports 2,400,000 counts. This is gives ten (10) times the resolution for a wide range of inputs. For example, the SMU2055 measures 14VDC with 10uV resolution, while other 6-½digit DMMs are limited to 100uV resolution. This high dynamic range reduces the number of times you need to change ranges, allowing shorter test times.

A Family of Test and Measurement Plug-In Instruments
These USB DMMs are a great choice for burn-in, production test and R&D as well as portable applications. These US designed and built units should be considered for bench top, portable and automated test. All you need is a vacant USB port. No additional power cords or data cables are required. Measurements can be displayed on the computer monitor using a familiar looking DMM panel. The DMM can also be used in an automated fashion with a user-generated control program, utilizing one of many compatible software packages and operating systems.

The addition of this state-of-the-art USB DMMs to the existing lineup expands the offering of DMMs from Signametrics to 14 PXI, PCI, VXI and USB models, enabling users to select the best fit product, at the lowest possible price, using the same software.
