Meters are designed for registration of active energy in one direction in 3- or 4-wire networks of alternating current and operate either autonomous or within AMM
Basic functions:
- Measurement, registration, storage, output to LCD monitor and transmission through interfaces IrDA of the following data:
- quantity of registered active energy separately by each tariff and total of all tariffs
- total from indications reset
- for current day and for the beginning of a day
- for previous day and for the beginning of a day
- for current month and for beginning of a month
- for each of 11 previous months and for the beginning of month
- for current year and for beginning of a year
- for previous year and for beginning of a year
- Tarifficator of meter provides possibility of registration by 4 tariffs in 16 timing zones of a day for 4 types of days. Each month of a year is programmed with individual timetable. Minimum tariff working interval within a day – 1 minute
- Additionally meter provides output to LCD indicator and transmission through wire interfaces of the following network values:
- instantaneous values of active power by each phase and by phases total;
- functioning values of phase currents, voltages, angles between network frequency phase voltages;
- network frequency;
- power factors by each phase and by phases total
- Input of active power and energy limits and programmable control of external consumer switch off load devices in case limits are exceeded.
- Meters programming in the mode of phases summation “on module” to prevent energy theft if meter current circuits connection phasing is wrong.
- Meter journals (circle, 10 records for each event) register:
- meter on/off time
- phases 1,2,3 on/off time
- time of phase voltage exceeding/returning back from permitted limits
- devices opening/closing time;
- last programming time
- tariff timetable correction time
- time of exceeding set energy and power limits

Additional functions (modifications with F index ):
- Storage of single-channel archive of average power values of active energy power profile with voluntary integration time from 1 to 45 minutes with step 1 minute. With 30-minutes duration of integration the archives overflow time is 85 days.

Transmission of the following data about consumed energy with growing total |
- starting from beginning of meter operation on tariff and phases sum in case meter is programmed in one-tariff mode; |
- starting from beginning of meter operation on current tariff and phases sum on the moment of request in case meter is programmed in multi-tariff mode; |
Receiving of the following data: |
- built-in modem network identifier; |
- command of temporal switch to auxiliary data transmission; |
- current date and time |
