User upgrading
If you purchase a ROM from us to upgrade from a version less than 10.14 to a newer version you will need to set Calibration offset 17 to a value of 8. This will correct the charge current scaling factor within Pro-Trak to the older value used by earlier versions.
If Calibration offset 17 is not set to 8 then the charge current will be incorrect (normally lower than indicated on Pro-Trak) and charge capacities of > 5000mA will be recorded.
Pro-Traks that are returned to us for upgrade have the charge calibrated for the higher charge current (12 amp) and Calibration offset 17 with have a value of 10.
This facility was included to allow overseas customers to upgrade from a version less that 10.14 to a newer version without the expense of returning the unit to us for upgrade.
