Lascar EasyLog AC & DC Millivolt Data Logger – EL-USB-ACT
This standalone data logger measures and stores up to 127,000 AC or DC current readings. This logger must be used with an appropriate current clamp to take readings over a 0 to 1000 amp DC measurement range (0 to 723 amps 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 DC (707mV AC).
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.
