Operation
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.
Always use a filter to protect the sensor from particles inside the measuring area.
Turning the TecPen On
Press the On/Off button on the end of the TecPen to turn on the unit. The TecPen shows the battery
status and the oxygen level at ****. 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 after five minutes, the TecPen will switch itself off.
Selecting a New Configuration (optional)
Different product configurations called “recipes” can be selected if you are using multiple TecPens
and need each to have a unique product name in the data file for statistical analysis. To select:
1. Press the SAVE button for two seconds.
2. A list of pre-set configurations appears on the screen.
3. Press the SAVE button to scroll down or the START button to scroll up through the list
4. Press the SAVE button for two seconds to select a new recipe
5. After selection, the screen automatically switches back to measurement mode.
Taking a Measurement
1. Insert the gas lance into the gas-filled space to be measured.
2. Press the START button to take a continuous measurement.
3. The measured value is continuously updated on the display.
4. If **** is displayed the oxygen level is outside the measuring range. The display will always
show **** if a measurement is taken in normal room air.
Saving a Measurement
Press the SAVE button. The measured value currently on the display is saved in the TecPen's
internal memory.
A separate file is created for each day on which a measurement is taken. This contains the measured
values with a time stamp.
IMPORTANT! If you press and hold the SAVE button the display will switch to the menu display.
Turning the TecPen Off
The unit can be switched off by pressing the On/Off button for at least two seconds.
