2. Switch on Instrument
After switch on the instrument (press <I/0>)
the main menu appears on the display.
There will be displayed sub-menus with
following functions (not visible sub-menus
could be displayed by scrolling with arrow
keys):
Comb. measure. : operate combustion measurement
(Mean value : operate mean value measurement)*
(Atmospheric boiler : operate routine for atmospheric boilers)*
(Fan burner : operate routine for fan burners)*
(Diagnostic gas : operate routine for gas fireplaces)*
(Pressure tests : pressure tests according to TRGI)*
(Data processing : assign measurements / Data transfer)*
Adjustments : change adjustments of instrument
Control : check operating status of instrument (* = Option)
To perform measurements, select with the cursor keys the sub-menu
"Gas analysis" and confirm with <Enter>. The instruments starts
then a 1- minute calibration phase and the fuel types selection list is
displayed. The following fuel types acc. to 1
st
BImSchV are available:
Fuel oil (B)
Natural gas (B)
City gas (B)
Coke oven gas (B)
Liquid gas (B)
Use the cursor keys to select the desired
fuel type and confirm with <Enter>. The
instrument will then enquire if you wish to
use the data bank (only with option „Data
processing“).If you want to assign the
sampled data to a specific plant, so choose
„YES“ with the cursor keys and confirm
with <Enter>. („NO“ = measurement will
be performed without assignment).

3. Input or select a data record (Option)
The ecom-B has 300 storage locations
(option). In order to call up a data record
with data are already stored in the instrument or to create a new file, choose a data
record with the Cursor keys and confirm
with <Enter>
If you are choosing an empty data record, a designation (max. 16
indications) can be assigned. Proceed as follows:
-choose a keyboard with the <CAL.> key (5 keyboards are available)
-select a character with the keys <Store> (left), <Print> (right) and
the Cursor keys <up/down> (selected character is black deposits)
-take over the character with <Enter>
-repeat procedure, until desired designation is complete
-if you want to correct a character, proceed as follows:
-interrupt the selection with <Standby>
-select the character with the keys <Store> (left), <Print> (right)
and the Cursor keys <up/down>
-activate the selection with <Standby> and select the correct
character
-turn to Combustion measurement with 2 x <ESC> , „Comb. meas-
urem.“ and <Enter>.
If you are choosing a data record with data, you can call up the data
with <Enter> / <Store> / <Enter>. Now you can view the data with
the Cursor keys <up/down>.

4. Combustion Measurement
4.1 Prepare Combustion Measurement
Prepare instrument for measurement operation by making all connections (T-Room sensor and T-Gas, GAS and DRA of the 3chamber hose). Make sure that:
-the condensate pad has sufficient capacity
-the condensate pad is not soiled darker than no. 3 on the soot scale
4.2. Gas Analysis
Once the calibration cycle is over, the instrument enters the measurement mode. The measurement values could be displayed on 4
screen pages (3 x gas analysis; 1 x draught measurement – change
with curser keys):
Just position the probe in the exhaust pipe once the
calibration phase is over!
To obtain accurate measurement values it’s
important to re-calibrate the instrument after each
measurement (at the latest after one hour)!

The position of the measured and calculated values (gas analysis)
can be selected freely on the display. To change the position or the
composition, please proceed as follows:
-with <Enter> / <Display values> / <Enter> activate the first line on
the display
-choose with curser key the measured or calculated value
-with <Enter> activate the next line on the display and so on
-with <ESC> or <Enter> in the last line you leave this process.
The values for CO
2
, Efficiency, Losses, Lambda and the Dew Point
are calculated values. They just can be calculated when realistic
figures for the basic values like O
2
and the temperature are available.
It must be assured that:
O
2
< 20,5 % and T.Gas – T.Air > + 5°C
The dew point can just be calculated correctly if in the menu “Adjustments / Air pressure” the current barometric air pressure has
been entered. If the combustion gas temperature falls below the dew
point /between 25 and 65°C) the efficiency will be calculated with
condensation gain. In this case a (C) is displayed behind the efficiency . Correct measurement values are displayed after a delay of 1
to 1,5 minutes necessary for the gas transport to the sensors and to
establish a stable electrochemical reaction in the sensors. For storage and printing wait for the values to become stable. If the gas value still fluctuates for more than 2 ppm, the reason could be in an
unstable draft condition in the gas channel.
Once the measurement values are stable
and the results can be printed, press
<store> to transfer the values to the temporary memory. Data will be stored here for
later printout (the values of the temporary
memory could be checked by pressing
<Enter> / <store> / <Enter>. While checking the values the gas pump will be
switched off in order to spare the sensors.

CO-switch-off without purging pump
The internal program protects the CO-sensor for overload. In case
the limit of 2000 ppm (CO sensor without H
2
) is exceeded the gas
pump will be switched off. Remove the probe off the combustion gas.
Then press the key <CAL>. The gas pump turns on and purges the
instrument with fresh air. After sufficient purge time the unit switches
back to measuring mode (put the probe in the combustion gas).
CO-switch-off with purging pump (option)
The internal program protects the CO-sensor for overload. In case
the limit of 4000 ppm (CO sensor with H
2
) is exceeded a second
pump switches on and purges the sensor with fresh air. After sufficient purging time (blinking: "CO"), the sensor can be brought back
to the measurement mode with <Enter> / <CO MV ON/OFF> / <En-
ter> (the sensor can also manually be switched off by pressing <Enter> / <CO MV ON/OFF> / <Enter>).
4.3. Draft Measurement
The gas measurement mode already provides a trend indication of
the draught conditions in the combustion gas channel. As the pressure sensor is very sensitive and tend to drift, the value will not be
recorded by pressing <store>. It is therefore recommended to recalibrate this sensor prior to the actual measurement and results printing.
The current value will be displayed as well
as the remark to reset the zero point of the
sensor. Therefore disconnect the draught
hose from the instrument and press the key
<CAL>. By this the sensor is calibrated.
Connect the draught hose again with the
instrument. The exact measurement value
is displayed now and can be stored by
pressing <store> and added to the other
values already in the temporary memory.
The stored value will appear on the display.

4.4. Soot...Oil trace
Under „Soot...Oil trace“ the measurement results for boiler temperature, soot number and oil derivative can be entered. Select the corresponding line in the display and activate the entry by <Enter>. The
input for boiler temperature and soot number (3 measurements) can
be done as follows:
-select with the keys <store> (left) and <Print> (right) the position
which should be changed (corresponding field is blinking)
-enter the designated number with the curser keys <up/down>
By pressing the key <Enter> the entry will be transferred to the data
record of the measurement. The result of the oil derivative checking
will be documented as follows:
-set cursor to line „Soot...Oil trace“
-select the result with the key <Enter>
(“No”, “Yes” or “- - - “)
When all necessary entries have been made the entry can be closed
by pressing the key <ESC>. The measurement is now completed.
4.5. Record and print Measurement
After scrolling back to the gas measurement with the cursor keys <up/down> the
measurement can be transferred to the
internal memory with <Enter> / <Store to
memory> / Enter> (after successful storage an “M” will appear right down in the
display). Finally a print-out (IR printer required) of the results can be made (key
<Print>).
After the gas analysis, please transfer the recorded
data (intermediate memory) into the internal
instrument memory otherwise the values will
get lost by instrument switch-off!

Please care for a frictionless (direct sight) connection between the
sending diode and the receiving diode on the printer. The maximal
distance between both units should not exceed ca. 40 cm otherwise
a trouble free transfer is no more ascertained in any case.
4.6. After Measurement
Stow probe and probe tube in the device (only devices with aluminium cover) as follows:
1. Attach the probe to the designated fixation.
2. Slide the probe tube starting at the probe into the space between
device and case. Pass the hose here alternately from right to left and
from left to right.
Let the probe cool down before
stowing them!
