8.5.1 Configuration of the data logging option
1) Connect the gas inlet (white port) to the sample point. The yellow exhaust hose can
be vented a safe distance from the sample point; do NOT re-circulate back into the
system.
2) By selecting 'Next ID' the operator can select the ID which is being sampled at
present.
3) Once the ID has been chosen the analyzer will commence and complete its clean air
purge cycle.
4) To gain access to the data logging option the operator will be required to select the
'Special Action' key to obtain the special user options. The data logging option can
then be selected via 'Key 6' to configure the logging parameters.
5) Once the operator has confirmed the logging parameters, select soft-key 'Start
Logging'.
6) Once the logging function has been activated the analyzer will carry out a 30 second
warm-up (displayed below the temperature read out at the right of the main gas read
screen) and begin the first sample.
7) If for any reason during the logging cycle the inlet port becomes blocked, the
analyzer 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.
8) Select soft-key 'Stop Logging' to stop logging if required.
8.5.2 Profiling option
1) The 'Logging Mode' center soft-key toggles between 'Logging Mode' and 'Profiling
Mode' and pressing it will change the mode to the one the soft-key describes. For
example, when on the profiling page the key will display as 'Logging Mode' and
when on the logging page the key will display as 'Profiling Mode'.
2) To edit the parameter the operator will be required to select 'Key 3' to select the
number of reading required. Once the number of readings has been updated press
the return key to confirm parameter setting.
3) By selecting 'Key 2' the operator can edit the logging interval of their logging
preferences and then confirm the amendments by pressing the return key.
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
analyzer 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'.
