EL-USB-ACT AC and DC Millivolt Data Logger

EL-USB-ACT Millivolt AC Data Logger is paired with a current clamp that can measure both AC and DC. The AC Data Logger can store up to 127,232 readings over a 0 to 1000A d.c. range. (0 to 723A for a.c.)

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 1V d.c. (700mV a.c.).

EL-USB-ACT by Lascar Electronics is also an easy use logger. Users can easily set up the logger and view recorded data by plugging the data logger into a PC’s USB port. Free Easylog software is provided for easy navigation.

The Easylog software is simple. It has a section for the clamp scaling factor (the clamp input-output ratio of amps to millivolts). It also allows users to download recorded data from the logger. The recorded data can be used to graph, print, and export out to other applications.

EL-USB-ACT also comes with a high contrast LCD screen. This screen can show a variety of information. Such as current, power, energy, and cost. By pressing the button, users can also cycle through relevant data. Such as the recent, maximum, and minimum measurement values.

The data logger also comes fitted with 2 replaceable AA batteries.
