Product description
BRIGON 500 NT measures CO
2
, CO, differential pressure as well as flue gas and ambient air
temperature. The instrument calculates O
2
, CO
undiluted
, lambda, stack loss q
A
and efficiency
(Eta).
The data are displayed in function oriented measuring windows or user selectable window in a
back-lighted display.
When storing a reading, as for example Oxygen concentration O
2
, the readings of flue gas
temperature and ambient air temperature as well as the calculated values q
A
, differential
temperature, Eta and CO
2
are stored and can be optionally printed.
Sensor calibration takes max. 90 seconds and is performed automatically after switching on
the analyser.
Flue gas analyser has an integral watertrap with particle filter. Damp from the flue gas is
condensed and collected in the watertrap. The filter prevents smut particles from getting into
the analyser.
Please, note that your flue gas analyser is a product designed, manufactured and sold solely
for the purpose of flue gas analysis of burners. So, please, use your analyser and its
accessories only for this purpose.
Should you require to use it for other purposes, please obtain our written permission to do so
first.
Keep these operating instructions in a safe place close to your analyser as quick
reference should the need arise.

Commissioning, handling, storage
Your BRIGON 500 NT is delivered with 4 mignon batteries. Even in switched off mode the
batteries supply the clock of the analyser so, that the batteries are discharging even if you do
not use your BRIGON 500 NT.
Therefore we recommend to remove the batteries from your analyser if you do not need it for a
few days.
To prevent an impairment of the electrochemical sensors, please avoid the use and storage of
your BRIGON 500 NT in the environment of perspirating substances, e.g. solvents. Do not use
these substances for cleaning your BRIGON 500 NT either.
Take care that no moisture or condensate gets into the analyser.
Always make sure the batteries resp. rechargeable batteries (option) are fully
charged, especially if the analyser has not been used for a long period of time.
Important Safety Instructions
Your BRIGON 500 NT has been developed and manufactured with the utmost care to ensure
safe and reliable operation over many years. As with all electronic appliances, you must be
aware of certain general precautions. These are intended for your safety and to protect the
analyser from damage.
Read these operating instructions carefully, and keep all documents in a safe place for future
reference.
Be sure that...
• you carry out only the routine maintenance according to the operating instructions.
Opening the case of the instrument can cause damage to vital parts. The warranty will
become void if repair/modifications are undertaken by unauthorised persons!
• after having changed parts of the BRIGON 500 NT which have an influence on the
accuracy of the measurement, the concerned measuring channel should be tested at the
authorised service point for the reason of quality management.
• Magnetic fields – emerging from the magnets of the soft case of the analyser – can set
off sparks, can have an influence on pacemakers, can disturb electronic and
electrotechnical components and can delete data memories.
Take care that...
• your power outlet data matches that of the charger. If in doubt, consult your dealer or
BRIGON MESSTECHNIK directly.
• Do not expose your BRIGON 500 NT to temperatures higher than 50°C (as they can for
example occur in a car being parked in the blazing sun). It could happen that the analyser
will get overheated and that especially the electrochemical sensors will be destroyed. Do
also avoid temperatures below -20°C.

BRIGON 500 NT Page 5
• the charger is disconnected from the power outlet before cleaning the analyser. Use only
a damp cloth.
Do not use cleaning agents containing solvents!

Recommendations for measuring
Take measurements during normal operation of the burner. To avoid incorrect combustion
conditions during start-up, take measurements only after the burner has reached its particular
operating temperature (e.g. Boiler Water Temperature at least 60°C).
Before storing the readings, the sensors should be supplied with flue gas for at least 3
minutes.
The sampling point in the flue should be at least 2D (twice the diameter) downstream of any
bend. A sampling point at a different location is only allowed if it is not practically possible to
place the aperture 2D away from the joint (e.g. if there is a bend there) and the flue gas
conditions are stable and reproducible.
Before each measurement
Check the tightness of your probe unit (probe, O-rings, grip, filter, tubing and gas plug) from
the top of the probe to the end of the tubing with an appropriate testing device e.g. BRIGON-
tightness-tester for probes and tubes, Item.-No.: 3039.
The cables must be clean inside, i.e. no dirt or condensate, and it must not be pinched while
measuring.
Have your BRIGON 500 NT checked regularly by an authorised service point or directly by
BRIGON MESSTECHNIK. The CO
2
-sensor and the CO-sensor must be checked every year.
Take care that the gas outlet at the bottom of the analyser is always open.

BRIGON 500 NT Page 7
Operation
Switching
on By pressing the button you switch the analyser on. The sensors are
calibrated automatically. Make sure that the probe is not inserted into the flue gas
pipe and hold your analyser in fresh air.
On switch on, the analyser beeps 4 times and displays date, time and model
number. The countdown runs from 90 to 0 untill sensors are ready to use.
Through integral dynamic calibration the countdown might be finished within 20 -
30 seconds. Calibration will last longer as the analyser gets older or in case it
was overstressed with high CO concentration. If the repeated calibration was not
succesfull, sensors must be tested and, if necessary, replaced.
Note During calibration both temperature probes should be connected to the
device!
If the ambient air probe (T
2
) is connected to the analyser during the countdown,
this temperature probe is used for further measurements. In case any probe (for
example, flue gas probe) is connected to the analyser during countdown, the
temperature, measured by the flue gas probe will be used for further
measurements and calculations as T
2
. If no probe is connected, the analyser’s
internal ambient temperature sensor will be used untill the analyser is switched on
the next time.
Selecting
fuel type
Turn the rotary switch to the position MENU, press the buton twice, select
the required fuel type using the buttons , press confirm button and
turn the rotary switch to the required measuring program position.
Switching
off
By pressing the button you can switch your analyser off. The displays
counts down from 30 with the pump on to clean the sensors with fresh air. Make
sure that probe connected to the analyser is in fresh air.
Press the button to stop the countdown and return to the measuring mode.
Attention: BRIGON 500 NT will switched off only when the CO reading is below 20
ppm. If the CO reading is higher, the analyser displays CO HIGH and flush the
sensor further.
Navigation
Use the buttons to change the settings, to navigate in MENU, to
switch between the measuring windows, to zero the pressure sensor and to
choose the display order.
Take care that the buttons must be pressed shortly or longer to perform certain
functions in different measuring programs.

the button shortly and quickly release it. The analyser displays „Printing“
until this is complete. Press and release the key again to abort printing.
Back
lighting Press the button shortly. Backlighting of the display and pocket light turns
ON or OFF.
Be aware, that using the lights increases the power consumption of the batteries
and leads to a shorter opereating time.
Pump
The analyser normally operates with the pump on in any measuring mode. Press
the button shortly to switch the pump OFF or ON again.
When the pump is switched off, the analyser displays -PO- (Pump off) in the
corresponding display line and a double beep sound comes regularly.
Attention: the pump will not switch OFF if CO-reading is above 20 ppm. It
helps to protect the CO sensor from damage.
