19/05/2022 14:00 Swapped the Nitrogen Analyser at Four Lane Ends (1155100) with the faulty Gosforth analyser.

20/05/2022 10:45 Some local Mobile Data network issues plus difference in baud rate (changed new Gosforth Nox to work at 11520 baud for consistency at Gosforth Logger) meant this did not start reporting Nox till now.

Data between this period should either be oignored or will be missing.
