First of all I must say that I have a Energiekostenmeßgerät of "ELV" and thus had very good experiences have made! The company ELV is known that they can innovative, high-quality and durable electronic products are developed and points with a good price-performance ratio. The ELV Energy Master is a later successor of my EM94. The functions are diverse, but focused on a simple detectability and clarity. You can use the 5 keys all the desired functions quickly and with little effort erreichen.Es is a pure voltage electricity power or frequency measurement. Furthermore, you can choose 3 power tariffs and can extrapolate annual consumption and CO2 emissions ermitteln.Desweiteren The device saves the Max. And Min. Values during operation. However, all measured and calculated values after unplugging the device are again gelöscht.Möchte you've saved them, you have to decide for the next expensive model, with a surcharge of 10 degrees. Remarkable is the high accuracy and the display resolution to 1/10 point. Now short the juxtaposition of positive and less positive features:
++ Lot Capabilities ++ Possibility of energy costs extrapolation from 1day to 1 year ++ Easy operation ++ High resolution, high accuracy ++ Backlight and thus good readability ++ Used up ca.3500W performance + Good design + Buttons have a real pressure point + Price justifies the equivalent oo not very compact, in series sockets should be used for an extension oo data is not saved - no criticism, because that's just the entry level.
Because of the many outstanding features I forgive good conscience 5 Stars.
