Watch your
Operation
IMPORTANT! If the device is taken to a room with a significantly different ambient temperature, an
acclimatisation period of 1-2 hors is required.
Operating Principle
The principle of opto-chemical oxygen detection using TecPen is based on the change in emission
of fluorescent radiation from the fluorescent dye depending on the oxygen concentration. The dye
is excited and the resulting fluorescence event isabsorbed. The duration ofthis fluorescence event
-the so-called lifetime - depends on the amount ofadsorbed oxygen in the sensor layer and can
therefore be used todetermine the oxygen concentration.
Before You Begin
In a known gas with no particulate matterand no condensation the cannula (syringe) may be
connected directly tothe TecPen.However, in most cases before taking a measurement the hose
and filter should be attached to the TecPen to prevent contamination of the gas chamber. To do
this,place the hoseon the gas inlet (8) and fasten the filter to the other end of the hose. Attach the
cannula to the front of the filter.
Watch Your Step!
The back of the filter has a Luer lock closure. This must be turned into the
intended connection of the hose for proper installation.
Turning the TecPen On
Press the On/Off button to turn on the unit. The TecPen shows the battery status and an
oxygen value of 0.00%. This is a placeholder and not an actual measurement result.
The unit can be switched off by pressing the On/Off button for at least two seconds.
Taking a Measurement
The cannula is used to puncture the packaging to be measured. After inserting the cannula briefly
press the start button to to take a measurement. The measurement is automatically
terminated after 10 seconds. If the measuring time needs to be extended after the first
measurement has been completed press the start button again.
After eachmeasurement is completed put the protectivecap on the cannula to avoid injury.
Turning the TecPen Off
The unit can be switched off by pressing the On/Off button for at least two seconds.

Saving Data
Default Operation
After each measurement is completed, the currently displayed measured value can be stored in the
internal memory of the TecPen by briefly pressing the memory key . 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:

Customizing the Data File Format
The Product_Number, Product_Name and Product_EAN fields can be customized so that multiple
TecPens can be used and all will have different names in the data files. All data files can be further
customized by selecting different “recipes” from the menu.
To get started, you must have a file named Rezepte.csv loaded on the TechPen’s internal memory
card (Rezepte is German for Recipe). The sample file may be modified, or you can create a
rezepte.csv file in any spreadsheet program that can save a .csv file. For example:
A
B
C
1
100ABC
Scanner1
12345
2
200DEF
Scanner2
67890
The 3 alpha-numeric fields (do not use commas) in the table will replace the Product_Number,
Product_Name and Product_EAN fields in your output data files. By default, the first row will be
used. If you want to select a different recipe, you must do so from the menu options after you have
turned the TecPen on and before you begin collecting data.
