Operation
IMPORTANT! If the device is taken to a room with a significantly different ambient
temperature, an acclimatization period of 1-2 hours is required.
Before You Begin
The TecPen can be charged with any 5V USB cable and adapter. Full charging takes place in under 2
hours.
If the device is taken to a room with a significantly different ambient temperature, an acclimatization
period of 1-2 hours is required.
Before taking a measurement a filter should be attached to the TecPen to prevent contamination of the
gas chamber. To do this, place the tubing on the gas inlet’s male Luer lock fitting (8) and fasten the filter
to the other end. Attach the sampling needle to the front of the filter.
Note: All connections are made with Luer lock fittings. These must be securely engaged for proper
installation and seal.
Turning the TecPen On
Press the ON/OFF button to turn on the unit. The TecPen shows the battery status and a value of
*****. This is a placeholder and not an actual measurement result.
1. After turning it on let the TecPen warm up for 2 minutes to insure accuracy.
2. The TecPen can only be switched on when it is not connected to the charging cable.
3. If no buttons are pressed within five minutes, the TecPen will switch itself off. The
unit can also be switched off by pressing the ON/OFF button for at least two
seconds.
Taking a Measurement
The sampling needle is used to puncture the packaging to be measured. After inserting the sampling
needle briefly press the START button to take a measurement. The pump will draw a sample until it
reads the lowest stable group of measurements. If it cannot read a stable measurement the pump will
automatically shut off after 10 seconds. To try another measurement press the START button again.
Saving a Measurement
Press the SAVE button. The measured value currently on the display is saved in the TecPen's
internal memory.
Turning the TecPen Off
Switch the unit off by pressing the ON/OFF button for at least two seconds.

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 formatis as follows:

3. The TecPen appears on your PC like a USB drive with one or more saved data files.
4. Copy the files from the TecPen using your PC’s file manager.
5. Disconnect the TecPen properly before removing the USB device from your PC
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.
10
Customizing the Output Data File
The Product_Number, Product_Name and Product_EAN fields can be customized so that multiple
Tec Pens can be used and all will have different names in their data files. The TecPen can be
further customized by selecting different “recipes” from the menu depending on the job.
To get started, you need to modify a file named Rezepte.csv loaded on in TechPen’s internal memory.
The file can be downloaded via USB, modified and uploaded, or you can create a new Rezepte.csv file
in any spreadsheet program that can save a .csv file. The required format is:
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 always be
loaded when the TecPen is turned on. If you want to select a different recipe, you must do so from the
menu options after you turn the TecPen on and before you start collecting data.
Zero Point Adjustment
The TecPen uses 100% 5.0 pure nitrogen gas for zero adjustment. To calibrate the TecPen, it must
be first be purged of any remaining gas from previous use by running the pump for several seconds
until the device is filled with pure nitrogen. Follow the steps below:
1. Connect the TecPen to pure nitrogen at 1L/min flow and perform 2 measurements
to insure the device is completely devoid of oxygen.
2. Press and hold the START button, then press the SAVE button until the calibration
screen appears.
3. A screen will appear with the text "Recalibration 0%?" followed by "NO".
4. Press SAVE to switch to "YES".
5. If "NO" is selected, the operation is aborted.
6. If "YES" is selected, let the unit calibrate for at least 5 minutes.
7. Hold the the SAVE button until the screen shows “recalibrated.” The oxygen level on the
screen should now show 0.00%. If not, set the zero point again.
A video with these instructions is available at https://www.youtube.com/watch?v=FYy08FOLNYc
IMPORTANT!
Zero point adjustment may only be carried out with class 5.0 or purer nitrogen or the quality of the
oxygen measurement results cannot beguaranteed.
After zero point adjustment the original factory values are overwritten. If the adjustment has not been
carried out incorrectly, the original factory values can be restored by following the instructions on
this video
