The meter is designed for installation inside buildings or in cabinets, which protects against evironmental
influences.
2.1 Functionality
2.1.1 The meter has an electronic register and performs metering per four +1 (emergency) tariffs. The meter
has an opportunity to programm up to 16 tariff zones within a day (one daily schedule) in steps of one minute,
individually per every day in a week in a seasonal program.
2.1.2 In a case of clock fault, error or absence of tariff scheldule, the meter accumulates readings per
«emergency tariff». «Emergency tariff» is 5 by default.
The meter archives consumed active energy values per (4+1) tariffs and in total:
– on a cumulative total (in total from zeroing);
– for the current and 12 previous months;
– at the end of the month for 12 months;
– for the current and 36 previous days;
– at the end of the day for 44 days.
2.1.3 Time of register readings changing complies with requirements of IEC 62053-21:2003, IEC 62052-
11:2003.
2.1.4 Network parameters measurement
Meter measures mean square values of current and voltage, network frequency and active power.
2.1.5 Impulse output
The meter has an electric test output. Telemetric pulse frequency is proportional to consumed power. Meter
constant is a number of pulses per kW•h, depends on meter modification and is shown on the front panel.
2.1.6 Meter logs
The meter keeps events/states logs, logs of parameters programming. The events are recorded in the logs with
the time / date of their occurrence.
