I don't know if the crossfire is manufactured this way but the medical equipment I work with is made with the sample counter at -999800. Now when we install and test a new system, we must run so many water tests and actual samples to insure the integrity of the instrument. This places the counter very close to 000000 when we are done. Is it possible that the odometers are set under 0 miles to count for testing and such? Just a thought.
