Present Reading is 100 and Previous Reading is 91
- Sigma calculates the consumption: 100 100 (present read) - 91 (previous read) = -9 (negative consumption)
- As the consumption appears negative, Sigma checks if it is within the Clocking Threshold
- 90 (Clocking Threshold) / 100 (Previous Meter Reading) = 0.90 x 100 = 90
- As the difference is -9 (less than 90%) (the clocking threshold)
- Sigma calculates a negative consumption of -9
- As the consumption appears negative, Sigma checks if it is within the Clocking Threshold
...
- Sigma calculates the consumption: 120 (present read) - 51 (previous read) = -61 (negative consumption)
- As the consumption appears negative, Sigma checks if it is within 90% of the Clocking Threshold
- 51 (present reading) / 120 (previous reading) = 0.425. 0.425 is less than .90 (90%), The reading of 51 is treated as a having gone round the clock
- As the difference is more than 90% (the clocking threshold, Sigma calculates a positive consumption of 99,930
- It is assumed that the meter has clocked, so calculates 9999 (Max Value) - 120 (previous reading) + 51 (current reading) = 99,930
