Operating instructions for Gossen Metrawatt's MID Electronic Active Energy Meters, covering safety, wiring, pulse output, display, and parameter configuration.
This manual provides operating instructions for Gossen Metrawatt's MID Electronic Active Energy Meters, including safety precautions, wiring instructions, pulse output settings, display functions, and parameter configuration. It details how to configure current and voltage transformers, set pulse rates, and interpret display symbols. The document also covers error codes, calibration procedures, and contact information for technical support and recalibration services.
The meters are designed for industrial energy measurement and feature configurable parameters for different applications. Safety warnings emphasize handling live components, proper wiring, and calibration procedures. The manual includes diagrams and tables for terminal connections, pulse output configurations, and display symbol meanings.
| Pulse Output Range | 1 to 1000000 pulses/kWh |
|---|---|
| Display Resolution | 7-digit display with decimal point |
| Error Codes | E0VHi1 to E0cALib |
Ensure connector cables are not damaged and voltage-free while wiring. Disconnect input voltage if safe operation is no longer possible. Only trained personnel should work on live instruments.
Pulse output settings are configurable based on model and features. For example, U1281/U1289 have fixed 1000 pulses/kWh, while U138x models allow programmable rates from 1 to 1000000 pulses/kWh.
The display alternates between the error code and instantaneous power. Common errors include voltage or current overloads and frequency measurement errors.
Disconnect auxiliary or supply power briefly to reset the meter. This can be done after eliminating the error or after a malfunction.
