By capturing current data, the L411 loggers help identify potential issues before they become critical (e.g., overheating, overload, etc.). Recording can also provide evidence of a failure or deviation that caused a malfunction.
Loggers can be used to monitor and analyze energy consumption in buildings or on an industrial load to optimize energy efficiency.

These L411 current loggers can operate for very long periods when needed and are very easy to set up. The devices can communicate via their USB port and can also be networked via their Wi-Fi mode. The Data Logger Transfer software is used to configure the devices and to process all measurements.
