In the meter is used the modern element base of conducting foreign firms.

In the meter is a target signal appropriate to the international standard DIN 43864, which allows using it as the primary gauge in the automated systems for the accounting of the electric power.

The meters has the strengthened protection against the non-authorized external influences: magnetic fields, handicaps, mechanical influences, etc. and also from thieving of the electric power.
