EL-USB-ACT AC and DC Millivolt Data Logger

When used with a current clamp, this standalone data logger measures and stores up to 127,232 AC and DC current readings over a 0 to 1000 ADC measurement range (0 to 723 A for AC). In ‘energy monitoring’ mode, this data is converted into power, energy (using a user defined voltage value) and cost (using a user supplied energy unit cost). The millivolt measurement mode allows for direct measurement of voltage, up to 1 VDC (700 mVAC.).

The user can easily set up the logger and view downloaded data by plugging the data logger into a PC’s USB port and using the free software. The software has provision for a clamp scaling factor (the clamp input-output ratio of amps to millivolts). 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. The data logger is fitted with 2 replaceable AA batteries.
