meter reading

im on economy 7 and have 2 readings please could you tell me which one is day and which one is night because im worried ive given wrong readings as im now in debit and never been before, there is a third reading but i think thats just the two readings added up together, my metre is incredibly old.
kind regards

Hi @Hopscotch

Your Day reading is the lower one around ~35000 kWh and the higher one is the Night one.
