1.5 ecom-EN3 Option heated probe for soot measurement
Heated probe for soot measurement
In order to perform a measurement of the soot content in the flue gas from oil firing systems,
a filter paper is introduced into the exhaust path of the probe where the soot deposits during
the measurement
On the basis of the deposited amount of soot on the filter paper (blackening), it is possible to
compare optically with a scale, which is the soot number This makes it possible to evaluate
the amount of soot in the flue gas
The filter paper is heated in the probe to prevent the flue gas from cooling too much This
cooling of the flue gas would lead to condensation of water vapour from the flue gas and will
distort the result of the measurement
Hint
As an alternative to the heated probe a hand soot pump can be used. The
possible condensation of water vapour is however not prevented with a hand
soot pump.
Hint
For further information on the procedure for soot measurement with the heated
probe please refer to chapter "4.7 Soot...Oil trace"

ecom-EN3
Page 13
1.6 ecom-EN3 Option hand soot pump set
Hand soot pump set
In order to perform a soot measurement in the flue gas from oil firing systems, a hand soot
pump can be used
By a prescribed number of suction strokes with the hand soot pump, a defined amount of flue
gas is drawn through an inserted filter paper On the basis of the deposited amount of soot
on the filter paper (blackening), it is possible to compare optically with a scale, which is the
soot number This makes it possible to evaluate the amount of soot in the flue gas
Hint
The hand soot pump is TÜV tested and characterized by high quality in its
processing and construction. This guarantees a long-term reliable function.
Hint
As an alternative to the hand soot pump a heated probe can be connected
directly to the measuring instrument. With this heated probe the possible
condensation of water vapour and thus falsification of the measuring result
can be reliably prevented.
Hint
For further information on the procedure for soot measurement with the hand
soot pump please refer to the manual for the hand soot pump set.

1.7 Gas Cooler (option)
Hint
The ecom-EN3-F transport variant professional case is standard with a gas
cooler.
Gas outlet Gas inlet Level monitoring
ondensate
evacuation
Peltier element Fan
Exhaust gas with a temperature over the steam dew point (35 - 65 °C) is flown spiral via a
long gas path thru a surface coated metal body with good thermal conductivity The gas
radiates its heat to this metal body A Peltier element (semi-conductor cooling element) flown
by a continuous current is thermal connected with this body and with a second metal body
with cooling ribs and ventilation slots
The flow thru the Peltier element creates a heat transfer from WARM to COLD, drains the
heat of the metal body flown by gas and conveys it to the outer cooling body This heat is
conveyed thru a vertical forced ventilation to the surrounding air
The condensation issued by the heat loss of the gas drops in a receptacle and is pumped out
on request by a periodically working hose pump
Hint
When the gas cooler is active the power requirement of the instrument
increases considerably. Therefore the cooling capacity of the gas cooler in the
battery operation is reduced.
Hint
The gas cooler can be deactivated in battery operation.
 To deactivate the activated gas cooler press the <Enter>
key when the measuring menu is active. Choose the menu
point "Peltier I / 0" and press the <Enter> key again.
 To reactivate the deactivated gas cooler repeat the
above steps.

1.8 Data Memory
When an SD card is inserted into the device, point measurements and data logger records
can be stored
Insert SD card as shown
° To start point measurements or data logger records, insert the SD card as
shown in the SD card slot and let it fully engage
Hint
The SD card must have the following characteristics:
- min. card volume 32 MB - max.32 GB (UHC)
- card formatted on 16 bit FAT or FAT32
WARNING
Never pull out cards during data record - data loss and damaging of the multi-
media-card are possible!
All values of a point measurement are stored in a text file with the name "J2KDV-xx txt" The
text file is stored automatically in the main directory of the SD card
All values of a data logger record are stored in a csv file with the naming
"J2KDL-xx csv" Sequential files are automatically numbered from 0 99
The data in the text file and the csv file are stored in the same structure
You will find further information on the data format in the chapter "Technical data"
The files can be transferred to a PC using a card reader Both file types can be imported or
opened using MS Excel

Page 16 ecom-EN3
1.9 ecom-EN3 Option Interface Wi-Fi (WLAN)
If the instrument is equipped with the Wi-Fi option, this interface can be used to display the
current measured values in an App of ecom The following functions can be used in the App:
- Live display of current measured values
- Export of stored measured values as * pdf or * csv
- Activate the function "Print measured values" on the measuring instrument
- Activate the function "fresh air purge CO sensor" on the measuring instrument
Hint
For the start-up of the Wi-Fi interface and for further information on the
corresponding settings please refer to the chapter "Adjustments".
1.10 ecom-EN3 Option interface BLE (Bluetooth Low Energy)
If the device is equipped with the BLE option, this interface can be used to display the current
measured values in an App of ecom The following functions can be used in the App:
- Live display of current measured values
- Export of the stored measured values as * pdf or * csv
- Activate the function "Print measured values" on the measuring instrument
- Activate the function "fresh air purge CO sensor" on the measuring instrument
Hint
For the start-up of the BLE interface and for further information on the
corresponding settings please refer to the chapter "Adjustments".

2. Measurement Preparations
Hint
Make sure that before each measurement
- the device has no visible defects
- the measuring system is tight (see leak test chapter 11.5)
2.1 Turn on the instrument and check the battery
The instrument is switched on with the <I / 0> key
Hint
After switching on the instrument or before starting a measurement check the
charging status of the battery.
 Check the charging status of the battery in the status line and /
or in the menu "Control".
The instrument is supplied with charging power supply The instrument can also be operated
with the internal battery for an extended period of time
When recharging the battery is necessary, the instrument will emit a battery warning This is
done acoustically and via a message in the display
Hint
The battery warning is activated when the battery voltage is less than 6.5
V. Less than 6.0 V the operation with battery is no longer possible
 The operation must continue via the charging power
supply.
WARNING The instrument is operated with a Li-Ion battery!
The battery must be replaced only by qualified personnel or by ecom or an
ecom authorized service center.
