Multifunctional Variants – Additional Parameters

Depending on the type of multifunctional variant, the meter is also capable of acquiring reactive power and displaying up to 26 additional measured quantities.

As a result, voltage level, utilization of individual phases, reactive power component and the functioning of compensation systems can be evaluated at any time by simply pressing a button without any additional measuring equipment.

Extensive Initial Calibration at the Factory

The meters comply with the MID directive which is valid throughout Europe and in Switzerland, and are shipped with initial factory calibration. They can be used immediately for billing purposes. Lead-times and costs are reduced as a result. Conformity assessment is conducted in accordance with modules B and D, and a declaration of conformity is included in the operating instructions.
