Description

AL-2VA Single Phase Energy/Power Logger

The AL-2VA is designed to allow users to monitor one voltage channel and one current channel. Allowing users to monitor the main voltage supply and the load current, therefore enabling staff to determine the energy consumption of various appliances or items of equipment.

Setting up the Electrocorder AL-2VA is easy, making it suitable for non-technical staff. Using the supplied (free) Windows software, Electrosoft; input the location details for the logging and choose the logging period. Electrosoft will print the necessary dispatch/ return documentation including user instructions. All data is included in a database of dispatches and returns, allowing you to track the location of multiple loggers.

Why is the Electrocorder better than other similarly priced competitors? The Electrocorder range uses a constant sampling technique, unlike the single reading of competitors. When the loggers start to record, they sample every channel 16 times per cycle, a cycle is 16ms at 60Hz. At the end of each averaging period, 3 quantities are saved for each channel, the True RMS average, the Max, which is the highest cycle value during the period, and the Min, the lowest cycle value. This means that it will record all the peaks and troughs which are one cycle or longer. The voltage and current levels are stored with dates and times. With the backup battery, the logger can continue to record for months. On the logger, data recording is signified by a flashing green light. A red light advises users that the unit has completed recording.

When the logger has finished recording, the stored data is uploaded to a PC via the supplied USB cable. Using Electrosoft, the recorded voltage and current levels have dates and times that can be viewed in both tabular and graphical form, exported to a spreadsheet, or saved to a file. Graphs can be printed showing the recorded levels and the allowable tolerance bands. Electrosoft also provides an internal database that effectively manages the distribution of multiple loggers.
