Compact USB DMM outperforms desktop units

USB digital multimeter offers ten-times the resolution of typical 6.5-digit DMMs for a wide range of inputs.

New from Signametrics Corporation, the SMU2055 USB digital multimeter offers the features of a benchtop DMM in a package measuring just 127 x 178 x 33mm and weighing only 227g.

The device is powered directly from the USB connection, and consumes only 1.5W, making it ideal for use with a laptop in portable applications.

Measurement capabilities include: four ranges for each of DC voltage and current and true RMS AC voltage and current; six ranges of two- and four-wire resistance measurement; four user selectable currents from 1uA to 1mA for diode testing; up to 250 readings per second; and fast range and function changes.

Whereas most 6.5-digit DMMs are limited to around +/-1000,000 A/D counts, the SMU2055 offers +/-2,400,000 counts.

This is gives ten-times the resolution for a wide range of inputs.

For example, the unit measures 14V DC with 10uV resolution, whereas other 6.5-digit DMMs are limited to 100uV resolution.

This high dynamic range reduces the number of times you need to change ranges, allowing shorter test times.

These USB DMMs are a great choice for burn-in, production test and R and D as well as portable applications.

These US designed and built units should be considered for benchtop, 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, using 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.

Installing this USB unit is short, easy and smooth.

Signametrics does not try to enslave or channel customers to any specific software package.

Therefore the drivers are designed to interoperate with as many different systems as possible.

Our growing list of supported packages include C++, Visual Basic, Net, LabView, LabWindows/CVI, C#, Delphi, Matlab, VBA, Word, Excel, ATEasy, HPVee and a lot more.

Operating systems include all Windows flavours, 32bit and 64bit Linux and TenAsys' INtime.

The SMU2055 USB DMM is priced at US $695, and is available on two to four weeks delivery.
