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  ressing 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 that can be imported into a  spreadsheet program. The file name is YYY-MM- DD_oxygen_logfile.txt. The data  ile 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.
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 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.  ll  ata files can be further customized by selecting different “recipes” from the menu.
To get started, you must have a file named exactly Rezepte.csv loaded on the TechPen’s internal memory card. The sample file may be modified, or you can create a new  ezepte.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,  he first row will be used. If you want to select a different recipe use the menu option before you begin 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  ump 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 be guaranteed.
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  ollowing the instructions onthis video: https://www.youtube.com/watch?v=FYy08FOLNYc
