Quick Start Guide

Perform a measurement

1. Acclimatize the device to the surrounding temperature (1-2 hours).

2. Press ON/OFF to switch on the TecPen.

3. The PWR LED will light up green.

4. The TecPen will indicate the battery status and oxygen level with ****%.

5. The TecPen will take 2 minutes to warm up.

6. Connect the gas inlet of the TecPen to the provided filter and connect the sampling needle

onto the filter using the Leur lock.

7. Optional: Connect the tubing to the TecPen. Put the filter onto the free end of the tubing.

Then connect the needle to the filter.

8. Take a septum and place it on the package. Make sure that that the septum is placed on a

place where enough gas is available to make the test.

9. Insert the needle into the gas-filled space to be measured.

10. Press START immediately after piercing the sample.

11. The “MEAS" will appear on the display. The oxygen value, will change continuously during

measurement.

12. If "****" appears your measured value is outside the measuring range.

13. Once the measurement stops changing, press START again to stop the measurement.

14. Press SAVE to save the measured value. The saving process is indicated by "LOG" on

the display. The value is stored in the internal memory.

15. Press ON/OFF again to turn the TecPen off.

For additional settings and features refer to the sections in this manual.

Introduction

The TecPen Handheld MAP Sensor is designed to provide fast, accurate measurements of

gas concentrations in closed or pierce-able containers. It uses an optical gas sensor with

OLED display as well as USB connectivity. This makes it an excellent tool for:



Food packaging in protective gas atmosphere (MAP packaging)



Headspace of vials, cell breeding vessels, infusion containers, syringes



Micro-bioreactor systems

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.

Menu Display

In normal use the TecPen has 5 screens that can be viewed by pressing and holding the

SAVE button. It is not possible to switch through the screens in reverse order.

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 formatis 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 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:

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
