Devices that support the EN50160:2010 standard are configured by default to measure a low voltage supply where the standard nominal value Un = 230 V (either between phase and neutral, or between phases) for systems with a synchronous connection to an interconnected system. If your measured system is different, you must manually configure the meter to reflect the characteristics of the system being monitored.
Your meter presents power system characteristics according to a set of guidelines as defined by EN50160:2010.
Use an uninterruptible power supply (UPS) to help ensure proper EN50160 operation during a power outage situation.
Failure to follow these instructions may result in lost data.
