Emptying the condensate container
• Disconnect tubes (1) and (5).
• Unscrew the condensate container’s upper (in the arrow’s direction)
sealing plug (3) and empty the condensate that has accumulated.
• Unscrew the pocket star filter (2).
• Clean and dry all parts.
• If the pocket star filter (2) is heavily soiled or not working, replace it.
• Both sealing plugs have a gasket. Make sure that these gaskets are
correctly inserted and undamaged. If they are damaged, replace them.
• Reassemble the condensate trap.
6.7 CHECKING THE CONNECTIONS AND CHECKING
FOR LEAKS
• Check all connections to make sure they are fitted properly.
• Check all tubes, tube connections, and the condensate container (from the
probe tip all the way to the gas port on the BluFlame) for leaks.
The BluFlame features an integrated automatic test for checking
the gas circuits for leaks. The corresponding procedure is described
in section 9.4, “Leak test,” on page 17.
6.8 TURNING ON AND ZEROING
• Tap the display and then the Power icon.
 ➡The BluFlame will run a zeroing routine automatically.
Make sure that the probe is not in the flue gas stream
during zeroing.
During zeroing, a blue bar will be shown at the
top of the display in order to indicate the zeroing
routine’s progress.
Once the zeroing routine is complete, the
BluFlame will be ready for measurements.
If any of the sensors are faulty, this will be
detected during zeroing and indicated with an
error message.
Running the zeroing routine again
• You can run the zeroing routine again during operation. To do so, go to the
“Measurement” main menu and select the “Zero setting...” option.
Carrying out Measurements
Every BluFlame features the full functionality required to carry out
flue gas measurements. Following is a description of the process for this
flue gas measurement.
After it is turned on, the BluFlame will have the Measurement menu active.
7.1 SELECTING A MEASURING PROGRAM
• Under “Gas measurement,” select one of the four defined measuring programs.
or
• In the “Gas measurement” main menu, tap the “Start button” to directly
start the most recently selected measuring program.
7.2 READING SCREENS
The readings will be organized into five screens with 4 readings each, and
can be configured as described in section 5.4, “Configuring measuring
programs,” on page 10.
Both direct measurands such as oxygen content and temperature and
calculated values such as dew point, CO
2
content, etc. are available as
readings. In addition, it is possible to have the same reading be converted to
various different units, e.g., CO in ppm or mg/kWh.
Unavailable readings will be shown as hyphens. Reasons why a reading is
not available can include the following:
• An electrochemical sensor was diagnosed as being faulty during zeroing.
• External temperature sensors are not connected.
7.3 CO LIMIT
If the CO limit is exceeded, the CO readings’ color will change (red).
This CO limit can be adjusted – please refer to section 5.5, “Setting the CO
limit,” on page 10.
7.4 SPECIFIC MEASURING APPLICATIONS
Test Bed Program
The test bed program is used with test beds in order to test the BluFlame
with test gas in the measuring program.
No calculations are performed during this test, and no alarm will be emitted
if the CO limit is exceeded.
The test bed program has no relevance to you as a user, as it is not intended
for end user applications.
7.5 PRINTING OUT MEASUREMENT RESULTS
• In each measuring program, you can use the print-out button on the
reading screen / to print out the readings shown on reading
screens 1 through 5. Duplicate values will be skipped.
