Saving Data
Default Operation
After each measurement is completed and the pump stops running, the currently displayed measured
value can be stored in the internal memory of the TecPen by briefly pressing the SAVE
button. By
default, a new data file is created each day using the date as the file name and the measured oxygen
level and a time stamp as data.
Output Data File Format
The TecPen outputs a comma-delimited text file (.txt) with a header row that can be imported
into any spreadsheet program. The data file format is as follows:

USB Data Safety
Before unplugging the USB cable, the TecPen MUST be ejected properly like any other standard
USB device to avoid damaging the TecPen’s internal file system.
If the TecPen is unplugged from the USB port without first selecting the “Safely Remove Hardware
and Eject Media” option, all data still on the device may be lost.
