and NeoFox Sport begins logging data automatically. The name of this log file is automatically generated
when the data log begins in the format
nf_xxx.tsv
, where
xxx
is a 3-digit number for a filename that does
not already exist in the NeoFox directory.
When you select Oxygen Sensor | Sensor Setup | Data Logging | Turn data log off, then the file will be
closed. A new file is created the next time you select
Turn data log on
.
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 <tab> upload date <tab> upload time <tab> oxygen
<tab> oxygen unit label <tab> algorithm temperature <tab> sensor
temperature <tab> tau <tab> algorithm pressure <tab> 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:
