4) Once the logging parameters are confirmed, commence the logging by selecting the ‘Start Logging’
key.
5) If for any reason during the logging cycle the inlet port becomes blocked, the analyser will sense this
as a ‘Flow Fail’ and the pump will automatically retry until the reading can be obtained. As such care
must be taken when positioning the sample tubing to ensure water/moisture ingress does not
occur.
6) Select soft-key ‘Stop Logging’ to stop logging if required.
Select the soft-key ‘Exit’ to exit this menu and return to the ‘Main Gas Read Screen’.
