Important hints

The ecom

J2KN

pro

meets

the requirements of

DIN EN 50379 part of 2.

The

ecom

J2KN

pro

may

not be used for

continuous emission control!

Following minimum times must be kept, in order

to receive correct measured values:

-1 min. to calibrate the sensors at fresh air

-2 min. for stable measured values

The following substances impair the working of

the instrument:

-Cleaning agents

-Degreasers

-Wax polishes

-Adhesives

-Formaldehyde

Adjustments at burners and boilers

should be made

only by specialists, who are familiar with

this installations!

1. Charge the accumulator regularly (Charge not

used instrument min. once a month)!

2. Never store the instrument with unloaded

battery!

Important hints for using IR bench

Please start every 15 min. a fresh air calibration by

using the infrared bench (especially with methane) to

get accurate measurements

(Adjustments / Re-Calibration)!

Please switch on the instrument 15 min. before star

ing the fresh air calibration, in order to bring the in-

frared bench on operating temperature!

2. Gas cooler (option)

Exhaust gas with a temperature over the steam dew point (35 to

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 (semiconductor cooling element)

flown by a continuous current is thermally 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 re-

ceptacle and is pumped out on request (either by the user or due to

the level monitoring) by a periodically working hose pump.

The sucking capacity of the gas conveying pump avoids a sufficient

dwell time of the gas with the condensate, so that wash out reactions

(NO

O > H

) do not take place.

At the cooler outlet the gas has a temperature of ca. 5 °C with a rela-

tive saturation of nearly 100 % relative humidity (corresponds to a

water steam content < 7 g/m

3. Power supply

The basic module of the ecom-J2KN

pro

is delivered with internal

loading unit. The instrument can be operated upon a longer time

period with the internal accumulator (6 V; 7,2 Ah). Connecting the

internal charging unit to mains power is only compulsory to recharge

the accumulators and to operate the heated probe system.

The accumulators should be recharged when the instrument shows a

corresponding message (acoustical warning and display infor-

mation). The accumulators loading stand can be checked, looking at

the voltage information on the display (menu "Control"). The battery

warning is activated when the value „ACC.B“ is smaller than 6 V.

By 5,8 V the power operation via battery is no more possible. The

instrument must be further powered via internal charging unit.

The control module of the ecom-J2KN

pro

is powered by 3 nickel-

metal-hydride accumulators (type AA). In case of need, the accumu-

lators can be recharged by docking the control module to the basic

module.

Hereby 2 functions can be selected („Adjustments / „Internal“ /

„Reloading function“ / <OK>):

1. Recharging function ON (<F1> = YES):

- batteries slowly and carefully recharged

- recommended adjustment by frequent use

2. Recharging function OFF (<F4> = NO):

- batteries quickly recharged

- recommended adjustment by occasional use

Used accumulators c

an be returned to us or brought

to recycling stations of public waste disposal compa-

nies respectively accumulators selling stores!

Never use batteries, to operate the control

module of the J2KN

4. Radio communication basic / control module

Thanks to the detachable control mod-

ule the basic module can be monitored

wireless. The basic module can be un-

locked as follows:

1. Press to unlock.

2. Tip control module forwards

3. Release control module from basic

module

The information exchange between

control and basic module is performed

via radio transmission (868 MHz) with a

coverage of approx. 50 m (by free

sight). The quality of the radio transmis-

sion is documented by a bar indication

in the main menu of the instrument

(long bar = good radio communication).

By interruption of the radio

communication, an error message is

displayed. By persisting disturbances of

the radio communication, a cable

(option) can take over the transfer

(connection betwen socket DATA on

control unit and socket DATA on basic

module).

If the basic module is switched off and

the control module not, so the display

will show an error message inviting to

fix the control module in its docking

station (helps also not to forget the con-

trol module). Observe this order, quit

with <ESC> and finally switch off the

control module.

5. Data record

The multi-media card enables the storage of both punctual meas-

urements and data logger records.

The values of punctual measurements are written in a text file

(J2KDV.txt). Those of data logger records in a csv file (J2KDL-xx.csv

/ xx = records numbered consecutively).

Both file types have the same structure and can be imported respec-

tively opened in Excel. See chapter „Technical Data“ for data format

information. The files can be transferred on the PC using a card

reader. The following conditions must be fulfilled for using a multi-

media card:

- ecom-J2KN

pro

- min. card volume 32 MB - max.32 GB (UHC)

- card formatted on 16 bit FAT or FAT32

- SD cards from SanDisk recommended

- PC with card reader

Insert the multi-media card as shown.

Take care that the card does not stand

out and hooks on.

Never pull out cards during

data record

data loss

and damaging of the data carrier possible!
