By collecting data on currents, L411 loggers help to identify potential problems before they become critical (e.g. overheating, overloading, etc.). Recording can also provide evidence of an outage or variation that has caused a malfunction. Loggers can be used to monitor and analyse energy consumption in buildings or on an industrial load, in order to optimise energy efficiency.

These L411 current loggers operate over very long periods if required, and are very simple to set up. The devices can communicate via their USB port, but can also be networked via their WiFi mode. The Data Logger Transfer software is used to configure the devices and process all the measurements.
