1.3. Ensure safety
•Use the device only for its intended use and within the parameters
specified in the technical data.
•Do not use any violence.
•Avoid dropping.
•Do not operate the device if there is any damage to the housing,
power supply unit or supply cables.
•Do not store the unit together with solvents and do not use desic-
cants.
•Only carry out maintenance and servicing work on this device that is
described in the documentation. Observe the described steps.
•Only operate the device in closed, dry rooms and protect the device
from rain and moisture.
•Only operate the unit with the supplied battery charger.
•Never use the probe tube and other metal parts / accessories as elec-
tric conductors.
•The analyser may not be positioned near open fire or extreme heat.
•The defined temperature range of the extraction probe / probe tube
may not be exceeded, the probe tube and/or the thermos-element
can be destroyed.
1.4. Device details
•The device is not suitable for long term (continuous) measurements
(this is a spot device).
•Before using the device verify the condition of the various parts of
the device, such as the probe, the ambient air conditions, the con-
densate separator, star filter and the connectors for damage and/or
blockages.
•When starting the device up it will take between 1 –3 minutes to set
to zero depending on the condition of the sensors and ambient con-
ditions. (Zeroing).
•The minimum zeroing time of the device to achieve correct measure-
ment values can be expected by 1.5 minutes.
•Exposure to acids; aggressive gases such as Sulphur; vapours 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. O2 - 2 years; CO - 2 - 3
years and NO - 3 years.
•The battery life is at least 500 charge-discharge cycles. With increas-
ing number of charging cycles the battery capacity (indicated in op-
erating hours) is reduced.

4First usage
Once the device is ready for operation, you can make some customised
adjustments during the first commissioning.
All settings can be changed at any time later.
4.1. Preparatory steps
•Unpack the device.
•Read the user manual in its entirety.
•The device has left the manufacturer completely assembled and
ready to use. Check if everything indicated has been delivered and
that there are no visible damages.
•Charge the battery for at least 8 hours.
•Check and modify date and time if needed.
4.2. Device settings
In the main menu Extras you can make in the submenu Settings the
following adjustments:
•LCD brightness
•Language
•Country for country specific fuel types and measuring
•Helping hints (on/off)
•Keyboard beep (on/off)
•Temperature units
Country
Option
By changing the country, the O2 reference
values will be lost. The fuel type lists are re-
set. Country specific parameters will be ac-
tivated. Please check if all the country spe-
cific parameters are correct, to assure that
the device meets the regulations for the
country that you are using this device

4.3. Setting time and date
In the main menu Extras and sub menu Date & time date and time can
be viewed and modified. The analyzer changes the time automatically
between standard time and daylight savings time.
The time and date must be modified in case the battery has been dis-
charged completely.
4.4. Setting CO limit
High CO concentrations in the gas stream can shorten the life span of
your CO sensor. The device can warn the user if the analyzer exceeds a
pre-defined CO limit. There will be both an acoustic and visual signal,
the device has no active CO overload protection. In case the pre-defined
CO limit is active you will have to remove the probe from the stack or
you take actions to lower the CO values.
The CO limit can be defined for each of the 4 measurement programs.
Using during the measuring the context menu and you can press the
CO limit key –the CO limit can be changed in 100 ppm steps.
4.5. Define the measuring window
The device can display 20 measurement values –4 values on 5 pages.
The user can define in what order he wants to see the available meas-
urement values.
Please select MEASURING WINDOW–CONTEXT MENU –DEFINE
WINDOW. You will then select the line that needs to be modified and
with left and/or right you can view and select available parameters. This
procedure will be done for each line.

MRU GmbH, D-74172 Neckarsulm 17 / 43
When completed you will exit this window using the button.
4.6. Select and modify Bluetooth parameters
Depending on the equipment, the analyser can be used to exchange
measurement data with external devices via Bluetooth:
•With MRU4u (App for Android and iOS smartphones)
•With MRU4Win
•With MRU Bluetooth printer
Depending on the software version of the analyser and the technical
specification of the Bluetooth interface, settings for data transmission
may be required. Please check in the following menu:
Adjustments can be made in the main menu EXTRAS / sub menu Set-
tings / sub menu Bluetooth.
If the settings window appears as shown above, please select whether
you are connected to an Android or iOS smartphone You realise a
connection to the Bluetooth printer or to MRU4WIn with the setting
“ANDROID".
The Bluetooth-Passkey (connecting code) is: 1234
