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.

Zero Point Calibration

The TecPen sensor is calibrated once at the factory and does not require recalibration. However, a zero point adjustment can be carried out to insure the most accurate reported oxygen values over the life of the sensor. See the chapter on “Zero Point Calibration” for specific instructions.

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:

Exporting Saved Data Files

1. Press the ON/OFF button to turn on the unit.
2.  Connect the TecPen to a PC using the supplied USB cable.
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.

Note: 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.

Customizing the Output Data (Recipe) File

The Product_Number, Product_Name and Product_EAN fields can be customized so that several TecPens can be used on the same QC line, and all will have different names in their data files to assist in QA reporting. These “recipes” can also be used if the TecPen is moved to different QC departments throughout the day. 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 and hold the SAVE button until the calibration screen appears.
3. A screen will appear with the text “Recalibration 0%?” followed by “NO”.
4. To exit recalibration, press and hold the SAVE button. You will read “Nothing Changed.”
5. To begin recalibration, press the START or SAVE button momentarily to switch the display to “YES”.
6. Once “YES” is shown calibration has started. Wait 5 minutes. Press and hold the Save button until the screen shows “recalibrated.” You will be returned to the main screen and the oxygen level should now show 0.00%. If not, set the zero point again.

A video with these instructions is available beginning at Part 1 for setup, then skip to Part 3 (2:27).

IMPORTANT!
Zero point adjustment may only be carried out with class 5.0 or purer nitrogen or the oxygen measurement results will not be accurate.After zero point adjustment the original factory values are overwritten. If the adjustment has not been carried out correctly (impure nitrogen, fresh air calibration, etc.) the original factory values can be restored by following the instructions on this video beginning at Part 2 (0:48). https://www.youtube.com/watch?v=FYy08FOLNYc
