Introduction
The Greenblue GB350 E Energy Cost Meter is designed to help you monitor and control the energy consumption of your electronic devices. This wattmeter provides comprehensive data on power usage, current, voltage, frequency, and allows you to calculate energy costs, making it an essential tool for identifying and reducing standby consumption from entertainment electronics such as televisions, radios, stereo systems, and satellite receivers.
This device offers high convenience and safety for your household. It complies with Protection Class I and features memory storage for your settings. Simply plug the meter between your appliance and the wall socket. After entering your electricity tariff, you can begin monitoring. A simple button press allows you to switch between various display modes to view the measurement data that interests you, such as current consumption in kWh, current power draw, or energy costs.
