The meter is also adjusted without guidance in seconds. 4 seconds the "" key press, with "+" and "-" set the current price of electricity per kWh and with "Confirm". Done. The set price is also stored when the device is not powered. To carry out the measurement simply plug the meter into the wall socket and the consumer in the meter. One can immediately read off the current consumption and the projected daily / weekly / monthly and annual consumption over time button. These values are just as long to read, as the meter is in the socket. For hard to reach doses can also simply an extension cord or a power strip switch between. To a meaningful value at periodic consumers to obtain such as refrigerators, the measurement should go over several days.
Thanks to the very high measurement accuracy of 0.1 W, me also some consumers have noticed that I would not otherwise have noticed. Example: four cell phones in the household, four chargers: calm consumption of 18 W. An old water heater: 4.5 W, etc.
I am very pleased with the unit and have the price be saved soon on the electricity bill again.
