Operating Principle

The principle of photochemical oxygen detection using the TecPen is based on the varied emission of fluorescence radiation of the fluorescent dye depending on the oxygen concentration. The dye is excited at 507 nm and the resulting fluorescence event is recorded at 650 nm. The duration of this fluorescence event – known as lifetime – depends on the quantity of adsorbed oxygen in the sensor layer and can thus be used to determine the oxygen concentration.
IMPORTANT! The label of the device must not be removed or modified without the consent of the license. Ensure that the label remains legible.

Operation

Settings Prior To Start Of Measurement

Acclimatization IMPORTANT! If the device is taken to a room with a significantly different ambient temperature, an acclimatization period of 1-2 hours is required Connecting TecPen to Switch on the theTecPen. the computer Use the USB cable to connect it to a computer.

IMPORTANT! Before disconnecting the USB cable, the TecPen must be ejected properly to avoid damaging the file system. If it is not properly ejected, all data still on the device will be irretrievably lost. Loading the recipe data All products/recipes are saved in the “Rezepte.csv” file provided on the

USB Stick. This CSV file is stored in the internal memory of the TecPen and can be opened when the device is restarted.
NOTE: We recommend that you change products/recipes in the CSV spreadsheet provided by us, as all fields that are required have already been submitted in this spreadsheet. Do not rename the “Rezepte.csv” as the TecPen is not able to read other names. Setting the time and Press SAVE for two seconds. Repeat this step until the date and time date display appears.

Press START for two seconds.

• ►► The year is underlined. To scroll down/decrease the number: SAVE To scroll up/increase the number: START After setting the year, press
• START for two seconds.
• ►► The year is saved and the next field is highlighted on the display. For a month, day and time, follow points 3 and 4.
• Press SAVE for two seconds to save all the settings.

Performing A Measurement

Press ON/OFF to turn on the unit

• The PWR LED lights up green.
• TecPen indicates battery status and oxygen level with ****mg/L or ppm.
• After the unit has been turned on, it will take approximately 2 minutes to warm up to ensure an accurate measurement. The device can only be switched on when it is not connected to the charging cable.
• If the instrument does not receive any input after 5 minutes, it switches off automatically.

Choosing a recipe / product

• press the SAVE button for 2 seconds.
• A list of preset products/recipes will appear on the display.
• Use the SAVE button or the START button to select the desired product/recipe.
• To select a product/recipe, press the SAVE button again for 2 seconds.
• After choosing, you will automatically return to the main screen.

Connecting the TecPen to the site of measurement

• Insert the pneumatic hose to the Inlet connection and a pneumatic hose to the outlet connector. Make sure that the outlet hose is in a sink or a bottle
• to collect the fluid. Let the liquid flow through the device via the inlet hose.
• IMPORTANT! Without a flow, you can’t get correct measurement results.
• ATTENTION: Do not apply more than 5bar of pressure.

Starting the measurement

• Press START to start the measurement. (If you have a smaller volume you can start the measurement before you connect the TecPen to the site of
• measurement. MEAS” appears on the display, below the O2 value, which changes continuously. If “****” appears instead of a measured value, your
• measured value is outside the measuring range. Optional: If you want to save the measurement continuously start the measurement with LOG.

Stopping the measurement

Press START to stop the measurement. Optional: Press LOG when you started your measurement with LOG Saving the measurement Press SAVE to save the measured value. The saving process is indicated by “LOG” on the display. The values are stored in the internal memory. A separate data file is generated for each day measurement is started. This file contains measurement data and time stamps.

Transfer of saved data

Switch on your TecPen. Connect the TecPen to your computer using the USB cable. TecPen appears on your PC like a USB drive and can be transferred as a .txt file.
IMPORTANT! Before removing your TecPen from the PC, make sure that it has been ejected correctly.

Performing a Zero-Point Adjustment

ATTENTION: DO NOT EXCEED A FLOW OF 1L/MIN WHEN YOUR TECH PEN IS CONNECTED TO A GAS FLASK
TecSense recommends using Nitrogen for the zero-point adjustment. Alternatively, also Argon gas is useable.

• Connect your TecPen gas inlet to your 0%-O2 gas (in the following called “GAS”) hose Switch on the GAS and make sure that the flow of gas will not
• exceed 1L/min Flush the TecPen for 5 min with the GAS Switch on the TecPen Press and hold START and immediately press and hold SAVE for two
• seconds. The pump is activated and you will see the Zero-point adjustment screen with the text “Adjustment to 0%?” with a “NO” underlined. Briefly
• press START or SAVE to switch to YES OR: press the SAVE button to select NO, if you want to abort the adjustment.
• Press the SAVE button to select YES and start the adjustment Wait at least 5 minutes to guarantee a correct adjustment. After 5 minutes press and hold
• the SAVE button for 2 seconds to confirm.
• Note:
• With a zero-point adjustment, the original calibration values are overwritten. If the adjustment has not been carried out correctly, the original values can
• only be restored by resetting the data with the original calibration file included as “config.txt” on the supplied USB Stick. The adjustment may only be
• carried out with class 5.0 or purer nitrogen, otherwise, the quality of the measurement results cannot be guaranteed.

Resetting the Calibration Data

In case the zero-point adjustment was not performed in the right way you have the possibility to reset your TecPen. Therefore, you will need the original configuration file which is provided on the supplied USB Stick. Connect the USB Stick to your computer Open the USB Drive on your computer and find the “config.txt” file Switch on the TecPen. Use the USB cable to connect it to a computer. Open the TecPen Drive on your computer
Drag and drop the “config.txt.” file from the USB Stick to the TecPen Drive. Eject the TecPen properly. Switch off the TecPen. Switch on the TecPen again.
The TecPen needs to be rebooted by switching it off and on again after the resetting. The TecPen is reset Perform a Zero-point adjustment exactly according to the manual IMPORTANT! Before disconnecting the USB cable, the TecPen must be ejected properly to avoid damaging the file system. If it is not properly ejected, all data still on the device will be irretrievably lost.

Cleaning Your Tecpen Fluid

The cleaning procedure is important if you use other fluids than water or carbonated water. IMPORTANT: The cleaning procedure has to be done in the exact order as shown in the table below.

Rinsing

After you have done your measurements rinse the TecPen Fluid with 1L of normal water.

Washing solution

Use one or two drops of the commercial detergent in 1L of water. Mix it without producing foam. Rinse the TecPen with 1L of the washing solution.

Rinsing

After you have done your measurements rinse the TecPen Fluid with 1L of normal water.

Ethanol

500mL of a 40% Ethanol solution can be used to rinse the TecPen Fluid.

Rinsing

After you have done your measurements rinse the TecPen Fluid with 1L of normal water.
