Second reading; good data
Reading of 20,200 dated 03/07/2008
Days since the previous (first) reading = 2 (03/07/2008 – 01/07/2008)
Distance since the previous (first) reading = 200 Kms (20,200 – 20,000)
Assumed Daily Rate = 200 / 2 = 100
Cumulative Meter = 220,000 + 200 = 220,200
Road User Charge Balance = 30,000 – 200 = 29800

Third reading; good data
Reading of 20,400 dated 04/07/2008
Days since the previous reading = 1 (04/07/2008 – 03/07/2008)
Distance since the previous reading = 200 Kms (20,400 – 20,200)
Assumed Daily Rate = Distance since the first reading / days since the first reading
= 400 / 3 = 133.33
Cumulative Meter = 220,200 + 200 = 220,400
Road User Charge Balance = 30,000 – 400 = 29600

Fourth reading: incorrectly recorded data
Reading of 40 dated 23/05/2012
Reading is less than the previous reading, so is deemed to be wrong. Options allow for clocked meter, changed meter, or wrong data.
Assuming wrong data in this instance choose the 'Exclude This Reading' option
Assumed Daily Rate = is left blank for this reading, and remains at 133.33 on the Plant Item
Cumulative Meter is unchanged
Road User Charge Balance is unchanged
The 'Exclude Reading' checkbox is ticked at the bottom of the screen indicating this reading will be excluded from calculations

Sixth reading: meter has 'clocked'
The Clock Value on this meter is 20,999
Reading of 100 dated 09/07/2008
The Clock Max Reading (20,999) is recorded on the reading at the bottom of the screen indicating the meter has clocked
Assumed Daily Rate = Distance since the first reading / days since the first reading
= 1,099 / 8 = 137.38
Increase in Cumulative Meter value since the previous (fifth) record
= Clock Max Value + This Meter Reading - previous (fifth) meter reading
= 20,999 + 100 – 20,700
= 399

Seventh reading: meter 'changeout'
Reading of 50 dated 09/07/2008
The meter has been changed
There is no reasonable basis to know what distance / time the Plant Item has traveled since the previous reading.

We therefore have:

  • Assumed Daily Rate is left unchanged
  • Cumulative Meter value is left unchanged
  • Road User Charge Balance is left unchanged
  • The Meter Change out box is ticked at the bottom of the screen
  • The Cumulative Meter value can be manually changed by editing the Cumulative Lift to Date value on the Plant Item Meter record if there is a record of the distance / time over the changeout period.
