Core TSIs : Meters : Meters - Concepts : Counter value modification
Counter value modification
The counter modification value is the difference between a counter’s current value and the new value (upward or downward).
Counter value modifications are added and maintained in Meters > Meter readings.
Example
After a fuel tank is refilled, its counter value needs to be updated upward with the quantity of fuel that is added.
If the previous reading was 5,000 and the new counter value is 6,000, then the modification value would be 1,000.
For the next reading entered (based on date-time), the consumption is displayed, based on the calculation given below:
Previous reading = 5,000
Modification value = 1,000
New reading = 4,500
Consumption = Previous reading + Modification value – New (last) reading:
5,000 + 1,000 - 4,500 = 1,500
