1.3. Ensure safety
•The analyzer may only be used for its intended purpose
and within its defined technical parameters. Don’t use any
force and avoid dropping the analyzer.
•Don’t use the analyzer when there are visible damages of
the enclosure, the charger or supply lines.
•Don’t store the analyzer together with solvents and don’t
use any drying agents.
•Only perform maintenance procedures that are described
in this manual and always obey the instructions.
•Only operate the analyzer in closed and dry rooms, protect
the analyzer against rain and moisture.
•Only operate the analyzer with the supplied battery
charger.
•Never us the probe tube and other metal parts / accesso-
ries as electric conductors.
•The analyzer may not be positioned near open fire or ex-
treme heat.
•The defined temperature range of the extraction probe /
probe tube may not be exceeded, the probe tube and/or
thermo-element can be destroyed.
1.4. Analyzer details
•The analyzer is not suitable for long term (continuous)
measurements (this is a spot analyzer).
•Before using the analyzer verify the condition of the vari-
ous parts of the analyzer, such as the probe, the ambient
air conditions, the condensate separator, star filter and the
connectors for damage and/or blockages.
•When starting the analyzer up it will take between 1 –3
minutes to set to zero depending on the condition of the
sensors and ambient conditions. (Zeroing).
•The minimum zeroing time of the analyzer to achieve cor-
rect measurement values can be expected by 1.5 minutes!
•Exposure to acids; aggressive gases such as Sulphur; va-
pours such as thinners, gasoline, alcohol and paint, etc.
can damage, reduce the life of, or destroy the sensors.
•The life of the sensors depends on how they are used,
maintained and treated. Typical average life expectations
are: O2 - 2 years; CO - 2 - 3 years and NO - 3 years.
•The battery life is at least 500 charge-discharge cycles.
With increasing number of charging cycles the battery ca-
pacity (indicated in operating hours) is reduced.

Lithium-Ion battery user guidelines
NOTE
The battery is inside the analyzer and is not accessible to
the end-user.
Below are some guidelines you need to know
about Lithium Ion batteries and the handling of
these .
•The rechargeable battery may only be used for this
DELTAsmart analyzer.
•Don’t charge the analyzer in extreme heat, don’t store the
battery in a hot environment and don’t throw the battery
into fire.
•Don’t try to modify the battery, shortcut it or put any me-
chanical force to it!
•The battery may not be used in or under water.
•Avoid mechanical force and don’t throw that battery.
•Don’t cut or squeeze the battery cables!
•Don’t carry or store the battery together with sharp ob-
jects.
•Don’t connect the (+) contact with the (-) contact or con-
nect these to a metal object.
•Not obeying the above instructions can cause heat, fire
and explosion.

3Description
The main task of the DELTAsmart analyzer is to assist with precision con-
trol and adjustment measurements of gas, oil and wood fired furnaces.
Available options for this and other analyzers can be found on the MRU
Homepage or speak to a member of our sales team.
Gas schematics diagram
In combination with the extraction probe (inserted in the stack) the in-
ternal gas pump of the DELTAsmart analyzer extracts a portion of the flue
gas and analyzes it using electro-chemical sensors.
The thermo-element in the probe tube measures the flue gas tempera-
ture and due to the construction of the probe pressure (draft) can be
measured as well.

3.2. The condensate separator (water trap)
During a measurement condensate is being collected in the condensate
separator. The maximum water level is marked with a ring on the bot-
tom part of the show glass.
Empty the condensate separator frequently to avoid water getting into
the analyzer.

4Operation
4.1. Power on and power down
The DELTAsmart is powered on using the display.
Touch the screen and the green ON button will appear, then press the
ON button to power on the analyzer.
Use the context menu button
to power the analyzer down.
Now press the red OFF button
to power the analyzer down.
Once the analyzer has been started it will make a self-test and then per-
form the zeroing of the analyzer. It is important that at this point the
analyzer is operated at ambient air and that the pressure ports are with-
out pressure.
4.2. Function keys
In all operation windows there are pre-defined function keys at the top
and the bottom of the screen.
At the top of the screen these are mostly the return key and the con-
text menu key.
At the bottom of the screen these are mostly the page up and page
down keys.
Dependent on the page that you are currently on, the function keys can
have different functions to allow faster access.
4.3. Context menu
The context menu-button offers additional functions. When pressing the con-
text key, you will see a variety of functions related to the window that you are
currently in.
There are also general functions like: switch off analyzer, exit window, close
context menu without action.

4.4. Combustion test
DANGER
Poisonous gas can be present
The possibility of death through intoxication.
Flue gases are extracted by the analyzer and then evacu-
ated into the ambient air.
►Only operate the analyzer in well ventilated rooms.
NOTE
Wrong measuring results
The extracted flue gas must be able to evacuate the ana-
lyzer without obstruction.
►The exhaust outlet at the rear of the analyzer may
never be covered during a measurement, never oper-
ate the analyzer in a transport case.
Start: starts a combustion test with the current selected program and
fuel type.
Press Combustion test, then select one of the 4 programs and then se-
lect the fuel type.
The measurements window has in total 20 measurement parameters, 4
parameters each on 5 pages. There are 2 ways to move from page to
page:
•Press the context key and then select page + or page -,
•Or simply touch the left or right border of the display to
jump to the next or previous page

4.5. Draft / pressure measurement on combustion test
The draft is measured using the DELTAsmart in combination with the extrac-
tion probe either before or after gas measurement.
While inside the measurement window you press the context menu key and
then select the draft/pressure key. During this phase the gas pump stops
working, and gas measurement values are frozen.
In the draft/pressure screen the measured values will be displayed. These val-
ues can be carried over as either draft or pressure value into the gas measure-
ment screen. (The difference between these 2 values are basically the pre-sign
and name before the value –a draft in the stack will be displayed as positive
draft)
NOTE
To avoid false readings
The position of the analyzer during pressure sensor ze-
roing is important.
►During zeroing the analyzer should be in the meas-
urement position.
With the return key you switch back to the gas measurement and the
measured draft value will be visible (unmodifiable) in a different color.
