Maximum current 32A, standby loss only 0.5 watts. Modular device for mounting on DIN-EN 60715 TH35 rail. 1 division unit = 18mm wide, 58mm deep. This AC meter with reset function measures the active energy based on the current flowing between input and output and stores the consumption in non-volatile memory. Like all meters without a MID declaration of conformity, it is not approved for monetary electricity billing in Europe. As with all Eltako AC meters, the accuracy corresponds to class B at MID (1%), the starting current is 20mA. The display is divided into 3 fields. Field 1: This display refers to the accumulated value in field 3. IIII slowly moving to the right = field 3 shows the accumulated consumption since the last reset. This is the normal display. S01 = field 3 shows the consumption for the last full hour up to S24 = 24 hours ago. T01 = Field 3 shows consumption for the last full days up to T95 = 95 days ago. Field 2: Current value of power consumption (active power) in watts (W) or kilowatts (kW). The display arrows on the left and right show the automatic switching between W and kW. Field 3: Accumulated value up to 9999kWh. Display up to 9.999kWh with 3 decimal places, from 10kWh with 1 decimal place and from 1000kWh without decimal places. Use the left MODE button to scroll through the display options and these are shown in field 1: S01 and T01 as described above. Finally, press MODE to see the country code for the set language. D for German, GB for English, F for French and ES for Spanish. Use the right SELECT button to increase the number displayed by 1 within the display options each time you press it and the corresponding value is shown in field 3. The last full hour becomes the hour before last, and so on. If the active language was selected with MODE, you can switch to another language with SELECT. If you exit the new language setting with MODE, it is active. 20 seconds after the last MODE or SELECT operation and if both buttons are pressed briefly at the same time, the program automatically returns to the normal display. Reset: Hold the MODE and SELECT buttons down for 3 seconds until RES appears in field 1. If SELECT is now pressed briefly, all memories are reset to zero. The program then automatically returns to the normal display.
