The VOLTCRAFT SEM 4500 is connected between the mains socket and the consumer and shows in no time at all quickly and precisely the energy consumption or the electricity costs in the selected currency.Measuring timeHow much energy is used in a certain time spent? The SEM 4500 terminates the measurement process according to specification. The socket is not switched off. The measuring time is on an hourly basis 0-23 hours or daily 0-7 days can be set. Measuring result compareUp to 3 measurements are stored and can later be retrieved and compared. Example: washing machine, measuring time 3 hours. When setting the washing machine are the consumption and thus the cost is higher? Extensive options thanks to two tariff entriesTwo different electricity tariffs can be entered for cost calculation (e.g. for day/night-time electricity). Furthermore, the entry of the CO² emission of the electricity tariff is possible, so that the measuring device can then show how much CO2 was produced while the
