Viewing the Data Log File Name
You cannot set the file name, but you can view the name of the current log file by selecting Oxygen
Sensor | Sensor Setup | Data Logging | Data log filename.
Setting the Data Logging Interval
You can also set the data logging interval via the Oxygen Sensor | Sensor Setup | Data Logging | Data log
interval menu selection. This can be used to reduce the size of the log file. The minimum data log interval
is 1 second.
Data Log File Format
The datalog file is formatted as a tab separated value file. This file can be easily imported into Microsoft
Excel or comparable spreadsheet programs. A single sample in the data log is formatted as follows.
millisecond count upload date upload time oxygen
oxygen unit label algorithm temperature sensor
temperature tau algorithm pressure sensor pressure
Where:
Millisecond Count = The millisecond counter of the NeoFox device at the time of the actual sample.
Because this value is stored at the actual sampling time, this value is a more reliable timing metric than
the “upload date” and “upload time” fields.
Upload Date / Upload Time = These fields represent the date and time that the sample was uploaded to
the DPU.
Oxygen = The oxygen measurement (in whatever units are currently selected).
Oxygen Unit Label = The oxygen unit label; either “ppm”, “%”, “Torr”, or “um/L”
Algorithm Temperature = The temperature that was used to perform the conversion from Tau to Oxygen.
If the NeoFox’s temperature source parameter is set to:
Sensor temp, then this is the sensor temperature.
Fixed temp, then this is the fixed temperature value.
None, then this is 200.
Sensor Temperature = The sensor temperature (in degrees C).
Tau = The tau value (in microseconds).
Algorithm Pressure = The temperature that was used to perform the conversion from partial pressure of
Oxygen to concentration or mole%.
If the NeoFox’s pressure source parameter is set to:
Sensor Pressure, then this is the sensor pressure.
Fixed Pressure, then this is the fixed pressure value.
None, then this is 101 – 325.
Sensor Pressure = The pressure (in kPa).
