The On-farm Irrigation System Calibration Tool, IRRIG8Lite was updated on 11 February 2014. The key changes are in the Centre Pivot and Linear Move Irrigator calibration protocols. The only difference is that the Collector numbering has been reversed, so that Collector Number 1 is now the one closest to the machine inlet. In the case of Centre Pivots that is the closest to the pivot centre. For Linear Moves it is the collector nearest the tractor. Minor changes include correcting a misnumbering in the Application Graphs. The help files and Field Sheets have been updated to reflect these changes.
