| Measured & Displayed Values | Up to ~30 real-time and cumulative electrical parameters: voltage, current, active/reactive/apparent power, power factor, frequency, energy (kWh, kvarh, kVAh), per-phase values, import/export values, tariff-specific energy, plus error/phase-sequence detection.

| Outputs & Interfaces | 2 programmable S0 pulse-outputs for energy values; built-in infrared interface; optional external interface modules for M-Bus, Modbus (RS-485), Ethernet / TCP-IP for remote reading/data-logging. (gossenmetrawatt.de) |
| Tariff & Metering Features | Double-tariff measurement (T1 / T2) — allows differential billing/tariff tracking over different time periods. (cdn.tecotecshop.com) |
| Compliance & Accuracy | Calibrated at factory, compliant with relevant standards (e.g. EN 50470-3 for active energy, EN 62053-23 for reactive energy), suitable for billing, industrial, commercial and demanding residential applications. (gossenmetrawatt.de) |
