Recording can provide evidence of a failure or deviation that caused a malfunction.

These L461 voltage loggers can operate for very long periods when needed and are very easy to set up. They can be used on photovoltaic systems up to 1500 V DC. The devices can communicate via their USB port and can also be networked via their Wi-Fi mode. Configuration of the devices and analysis of all measurements is performed using the Data Logger Transfer software.
