6. Eltako Alternating current meter
Energy consumption display with screen - smart metering for DIN rail. Standby loss is only 0.5 watts. The energy consumption display measures active energy like an AC meter based on the current flowing between the input and output, and stores the consumption in non-volatile memory. Like all meters without MID compliance declaration in Europe, it is not approved for monetary electricity billing. The accuracy corresponds to that of all Eltako AC meters of class B according to MID (1%), with a starting current of 20 mA. This allows the energy consumption display to accurately replicate the measurement of the meter installed elsewhere in the building for electricity billing. The display screen is divided into three fields. Total reset: To start storing the values with hourly precision, a total reset is recommended at a convenient time after installation. To do this, press and hold the Mode and Select buttons simultaneously for 5 seconds until RES appears in field 1.
