Lascar Electronics Inc.: Millivolt Data Logger

The EL-USB-ACT is a battery-operated, stand-alone data logger. When used in conjunction with a CT clamp, the unit measures ac and dc current readings over a 0-1,000-A range with a millivolt measurement mode for direct measurement of voltage up to 1 vdc (700 vac). An energy monitoring mode allows the data to be converted into power, energy, and cost using predetermined values for energy and cost established by the user in the software setup. According to the manufacturer, this allows not only the measurement of power usage by certain appliances, but the translation of that data into actual dollars spent on running them. To set up the logger, plug it into a PC’s USB port with the supplied USB cable. Use the company’s free software to name the unit, choose the measurement mode (current, energy, power, or voltage), logging rate, signal type, high and low alarms, the scaling factor of the chosen current clamp, and logging start time. When logging is complete, stored data can then be graphed, printed, and exported to other applications. The high-contrast LCD can show a variety of current, power, energy, and cost information. At the touch of a button, the user can cycle between the most recent, maximum, and minimum measurement values. Optional CT clamps are available.
