Features

Metering
- Measures forward/reverse active + 4-quadrant reactive energy; supports combined active/reactive energy.
- TOU metering; per-phase active energy measurement.
- Stores last 12 billing days’data (cut-off time configurable).
Demand Measurement
- Tracks bidirectional max demand, TOU demand with timestamps.
- Sliding window method (default: 15-min cycle, 1-min interval).
- Manual demand reset supported; stores last 12 billing cycles’
Real-Time Monitoring
- Measures voltage, current, power, power factor per phase.
- Threshold alarms for voltage/current/power factor excursions.
Clock

Temperature-compensated clock with 1Hz output; automatic leap-year adjustment.
Tariff & Time Zones
- 2 programmable time-zone/day-schedule tables (auto-switch).
- 14 time segments/day (min. 15-min interval); 12 tariff rates.
Event Logging
- Records: Programming (10 most recent), demand resets, time calibrations, phase loss (voltage/current), voltage reversal, cover opening, meter resets, overloads, power failures, remote trip/close commands.
- Permanent log for meter reset events.
Data Freeze

Instant freeze (last 3), hourly freeze (last 254), daily freeze (last 62), monthly freeze (last 12), billing-day freeze (last 12), minute freeze (300 days at 15-min intervals).

Power-Off Data Read

Wake via button or infrared ("68 11 04" command); non-contact wake disabled after 7 days without power.
Prepayment Control
- Remote top-up via public network/carrier.
- Alerts when balance ≤ threshold; disconnects load if overdrawn.
- Restores supply after balance update.
- Supports direct remote close/allow close commands.
Forced Power-On
- "Force Power-On" mode blocks all trips until deactivated.
- Restores supply without changing meter state.
