Energy consumption display with display - smart metering for mounting rail. Stand-by loss only 0.5 watts. The energy consumption display measures the active energy like an alternating current meter on the basis of the current flowing between the input and the output and stores the consumption in non-volatile memory. Like all counters without MID declaration of conformity in Europe, it is not approved for monetary electricity accounting. The accuracy is the same as for all Eltako AC meters of class B for MID (1%), the starting current is 20mA. This means that the energy consumption display reproduces the exact measurement of the meter installed elsewhere in the building for the electricity bill. The display is divided into 3 fields. Total reset: To start saving the values for hours, it is recommended to perform a total reset 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. If SELECT
