Article number: 8717853705083 View all from Ecosavers > View more: Energy meters > The EcoSavers Energy Meter measures energy consumption and calculates the consumption costs of connected household appliances. You can use it to discover which devices consume the most power and thus limit your energy consumption. This product uses an internal capacitor to store stored data. This capacitor must be charged before first use. Therefore, plug the energy meter into the socket for 10 minutes before first use. This is a unique feature of the device. Other energy meters work with rechargeable batteries for the memory function. However, if you do not use the device for a year, a rechargeable battery will be irreparably damaged, resulting in a device that you can throw away. The EcoSavers Energy Meter with large display has a capacitor. This retains the memory for approx. 5-10 minutes (so that you have enough time to change sockets while retaining data), but continues to function indefinitely, even if you do not use the energy meter for a long time. A capacitor is not damaged if you do not use it for a long time. After the energy meter is connected to the power outlet, the display will appear within 5 minutes. After 10 minutes of charging, the energy meter is ready for use. Insert the plug of the device to be measured into the energy meter. You are currently viewing an energy meter that is not suitable for power outlets in Belgium. This energy meter with earth is only suitable for use in the Netherlands.
