what this two means what the upper numbers calculate and what is wechselstromzähler?? and do i can self calculate how much electricity i used until now?

1. Do you have electric heating?

   Two counters could indicate two different tariffs (daytime/nighttime). The incentive is to have lower prices for heating in off-peak times.

   Wechselstromzähler: alternating current meter

   For calculation, you need the initial counter readings to calculate the difference to current reading.

2. I think “Wechelstromzähler” is the description of the whole counter, what’s more interesting is that on the right side it very faintly says “HT” and “NT”. It stands for Hochtarif and Niedertarif and should mean that the electricity used at night gets counted separately. This is usually used for electric heating, so it’s strange you don’t have any. But there are special contracts for this kind of electricity that bill the 2 positions separately, with NT being the cheaper one.

3. “Wechselstromzähler” is the word for the electricity meter.

   This meter is built for a system where two different tariffs operate, either one for power supply and one for heating, or one for a peak tariff (charged during the day) and one for an off-peak tariff (charged at night). Whether your electricity provider actually charges two different rates is another matter.

   Both figures show kilowatt-hours used. The top one (marked “HT”) is for the main or peak tariff, the bottom one (marked “NT”) for the secondary or off-peak tariff.

   Since this is an old-fashioned mechanical meter, you can’t easily see how much power you have used in a certain time period. Instead, you have to write down the numbers (you can ignore the last figure outlined in red — that’s a decimal fraction) at the beginning of the time period, and then at the end of that period read the meter again and read the new numbers. Then for each tariff — HT and NT — subtract the old reading from the new reading and you have the number of kWh you have used in that time period.
