Energy meter ORNO EM-5(GS) two-tariff wattmeter 16A 230V with LCD, internal battery, Schuko version

ORNO EM-5(GS) is a two-tariff wattmeter designed for single-phase 230 V installations with a maximum load of 16 A. The device provides real-time power and cumulative energy readings on an LCD display and stores tariff-specific consumption values to allow comparison between peak and off-peak periods. An internal battery preserves recorded data during brief power interruptions, making it suitable for continuous monitoring of household circuits and small appliances.

Advantages

The meter displays instantaneous power and accumulated energy values on a clear LCD, with separate registers for two tariffs to help track consumption by time period. Its compact Schuko-compatible enclosure and screw-terminals simplify installation in domestic sockets or distribution boxes. The internal battery ensures data retention when mains power is interrupted, and the 16 A rating covers typical household circuits and many portable appliances.

Suitable for

• Monitoring electricity consumption of home circuits and appliances
• Comparing energy use during peak and off-peak tariff periods
• Estimating running costs of individual devices
• Short-term energy audits in small properties

Key specifications

• Supply voltage: single-phase 230 V
• Maximum current: 16 A
• Two-tariff energy metering with separate registers
• LCD display for instantaneous power and cumulative energy
• Internal battery for data retention during power loss
• Schuko-compatible physical format for mains connection

How to use

Install the meter in line with the household socket or distribution point following local electrical safety regulations. Connect the live and neutral conductors to the appropriate terminals, ensure secure tightening of terminals, and switch the circuit on. The LCD will show real-time power consumption and accumulated energy values; use the device controls to view separate tariff registers. The internal battery does not require user replacement for normal short-term data retention but confirm battery status periodically as part of routine checks.

Usage recommendations

Use the ORNO EM-5(GS) on circuits that do not exceed 16 A continuous current. For accurate tariff comparison, reset or note baseline readings at the start of each billing period and avoid switching major loads on or off immediately before taking comparative measurements. Ensure installation by a qualified electrician when used inside distribution panels or when permanent wiring modifications are required.
