## Summary description

ORNO EM-4(GS) is a single-tariff energy wattmeter with an LCD display and built-in battery, designed to measure power consumption of Schuko-plugged appliances. It calculates energy usage in one tariff, shows real-time power and cumulative consumption, and stores readings during power interruptions. Suitable for home and small office use to monitor electricity consumption and estimate costs.

## Long description

ORNO EM-4(GS) single-tariff wattmeter with LCD display and built-in battery measures the power consumption of appliances connected via a Schuko socket. The device displays instantaneous power and cumulative energy consumption in a single tariff and stores readings during power interruptions thanks to its internal battery. It is designed for household and small office environments where monitoring and estimating electricity usage is required.
Advantages
The wattmeter provides a clear LCD readout of real-time power and total energy consumed, while the single-tariff measurement simplifies tracking for typical residential billing. A built-in battery preserves recorded data during outages, preventing loss of cumulative values. The integrated Schuko socket allows direct connection of appliances without additional adapters, and the compact form factor supports convenient placement near sockets.
Suitable for
Measuring power consumption of kitchen appliances (microwaves, kettles, toasters)
Monitoring energy use of entertainment equipment (TVs, sound systems, game consoles)
Estimating electricity use for small office equipment (computers, printers, routers)
Short-term tests to identify high-consumption devices and reduce standby losses
Key specifications
Measurement mode: single tariff (total energy and real-time power)
Display type: LCD for numerical readouts
Power supply backup: built-in battery to retain cumulative readings during power loss
Outlet type: Schuko socket for direct appliance connection
Data retained: cumulative energy values preserved across power interruptions
How to use
Plug the wattmeter into a standard wall socket, then connect the appliance to the device's Schuko outlet. The LCD will show instantaneous power consumption and the cumulative energy used in the configured single tariff. Readings update in real time; the built-in battery maintains stored totals if mains power is interrupted. To reset cumulative values, follow the device-specific reset procedure described in the user manual.
Usage recommendations
Use the ORNO EM-4(GS) for individual-appliance monitoring rather than whole-house measurement. For accurate short-term readings, allow the appliance to reach its normal operating state before recording values. Avoid using the meter with devices that exceed the rated current or power limits specified in the product manual.
