Figure 20: Data Logging page
During logging, data from the analyser is shown in the central area of this page.
The data is displayed in the following columns: time (in seconds), the raw signal
from the sensor (in mV), the oxygen value (in ppm scientific notation), pressure in
the units of choice, the time (in regional format), the date (in regional format), and
alarm status (displays either ALM1, ALM2 or ALM1&2 if activated).
To start data logging select the frequency of measurement by entering a time and
selecting a unit from the drop down list. For example if you wish to log data once
every minute type 1 in the box and select ‘Mins’ from the drop down menu.
You can open the NOTES window at any time by selecting NOTES from the ‘Data
Logger’ drop down menu. A small text box appears in which you can type a text
message. This note is then saved as a header in the data file set and can be viewed
along with the data.
You can either choose to have data logged continuously until ‘Stop’ is selected
from the Data Logger menu, or you can choose to set a time limit for data logging
by checking the box labelled ‘Time Limit’, setting the duration in the ‘Run For’ box
and selecting units with the drop down list. For example if you wish to log data
for thirty minutes type ‘30’ in the box and select ‘Mins’ from the drop down list.

Running the Data Logger
If you wish to save the data into a file for later use, check the ‘Save to File’ box
before selecting ‘Run’ from the Data Logger menu. You will be prompted for a file
name and location before data logging commences. The file and path information
will appear in the box at the top of the page labelled ‘Data File Name’. If you
forget to select file saving before starting a run, you will nevertheless be prompted
at the end as to whether you wish to save the run data.
