1.3. 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 various parts of the ana-
lyzer, 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 correct measurement
values can be expected by 1.5 minutes!
• Caution: Exposure to acids; aggressive gases such as Sulphur; vapors 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 num-
ber of charging cycles the battery capacity (indicated in operating hours) is
reduced.

3 Description
The main task of the OPTIMA7 analyzer is to assist with precision control 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 internal gas pump of
the OPTIMA7 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 temperature and due to the
construction of the probe pressure (draft) can be measured as well.

• CAUTION
Condensate is acidic
5 Maintenance
The OPTIMA 7 needs to the long value preservation only one very low maintenance need:
5.1. Cleaning
Taking good care of your OPTIMA7 will ensure long-term maintenance value:
The condensate from the container can be slight acidic and can cause
chemical burn.
► Immediately clean with plenty of water once you have encountered
acid
• After each measurement: removed the hoses of the sampling from the
OPTIMA7 and let them dry (condensate inside the hoses). Open and empty
the condensate separator and let it dry.
• Occasionally: clean the sampling line.
• The pleated filter in the condensate separator can be washed 4 to 5 time
(with your work clothes in the washing machine). The grade of contamination depends on the fuel types and the number of measurements performed. Replace the filter frequently when it looks dirty.
• The internal battery has only a minor self-discharge effect. If the analyzer is
not being used over a period it is recommended to charge the battery before storing it and then recharge the battery every 8 weeks.
5.2. Annual service and calibration
An annual service and calibration is highly recommended. Please contact your local service
partner for details.

6 Preparation for each measurement
6.1. Power supply
The analyzer can be used with:
• with the internal MRU battery (provided)
• with the MRU battery charger (provided)
External equipment may only be connected while the analyzer is switched off!
6.2. Auto OFF
The instrument is automatically switched off after 60 minutes. During a measurement or a
battery charging cycle the auto off is deactivated.
6.3. Measurement with battery charger/battery charging
(90...260 V / 50/ 60Hz) the battery will be charged
Once the battery is fully charged the analyzer will switch to trickle
charge mode.
At the moment, if the battery is fully charged and the trickle charge
mode begins, an acoustic feedback will be played.
6.4. Measurement with battery (Battery monitoring)
The battery symbol in the top right corner displays the current battery charge condition.
Approximately 15 minutes (depending on the analyzer configuration) before the battery
is drained, the battery symbol will start to blink red (about once per second).
When the battery is almost drained and the analyzer is not connected to the battery
charger within one minute, then the analyzer will switch off automatically to prevent deep
discharge of the battery.
6.5. Operation temperature
If the analyzer has been stored at low temperatures, it will require some time to equilibrate
to the ambient temperature before being switched on. If it does not equilibrate, condensation will occur inside the analyzer!
If the temperature is out of its operation range you will see the following messages on the
display: “Analyzer too hot” or “Analyzer too cold”
Once one of these messages appears you will not be able to use the analyzer, it will give an
acoustic signal until it has reached the specified operation temperature between +5°C and
+45°C

7.5. Measured value display
After the core flow search you will see the measurement values on the display.
Measurement values can be organized on three pages, each page displaying 6 measurement values.
The order of the display is operator settable.
There are direct measured values available such as Oxygen and Temperature as well as calculated values such as dew point, efficiency and CO2. You will also find the same measurement value in different calculated values such as CO in ppm or CO in mg/kWh.
Values that cannot be displayed are indicated with dashes. Possible reasons for value not
being displayed are:
Electro chemical sensor was detected as defective during zeroing.
External temperature sensors are not connected.
The measurement value T-Gas is usually read at the connector “TGas/AUX” (depending on configuration) or if not available from the connector “T1”.
There are three measurement windows available, with the arrow keys
left and right moving between them.
Zoom function, each with two values, is activated by moving the arrow
keys up and down. Moving arrow keys left and right pages between the
two zoom windows.
7.6. Non-continuous draft measurement
The Optima7 provides for a non-continuous draft measurement. The draft measurement is
disabled when a maximum time after zeroing has elapsed or a significant change in temperature has been detected by the instrument. The maximum time is configured to 10
minutes.
If the draft measurement is disabled it is displayed with “--.-“. The draft measurement can
be enabled again by zeroing the draft: F3 key “zero draft”.
To indicate that the draft measurement is not continuously available it is displayed in colour red.

The user can freeze the draft data by means of the F3 key “hold draft”.
The frozen data is displayed in green.
The unfreeze the measurement one has to exit the menu and enter
again.
All other measurements are processed continuously independent of the
draft measurement status.
7.7. CO-limit (without purging)
If the CO limit value is exceeded, the color of the measured CO values changes (red).
7.8. CO-purging (optional)
If the CO value exceeds the CO threshold, then the measured value is displayed red and air
purging pump is activated. This will protect the CO electrochemical cell from too high CO
gas concentrations.
If the CO value decrease below the CO threshold, then the CO value will be displayed again
in black colour.
Air purging pump is still running and can be deactivated only by accessing the “menu” key
and confirm “purge pump off”
Note: Unit switching: 10000pmm values are displayed in%.
The actual CO value will then be displayed again.
If a measurement with active purging will be stored, the device documented the device

The basis for the data storage of the OPTIMA7 are saved sets of sites inside the analyzer.
Each site has a distinct site number as well as 8 additional free text lines for names and address.
The analyzer can store up to 1,000 different sites.
New sites can be added in the analyzer. Modifications can be done using an external PC
program e.g. MRU Win.
Attention: New sites created in the analyzer will NOT be transferred back to the computer
program. When transferring data from the analyzer to the computer only measurement
data will be transferred, identified by the site number that has been assigned to the measurement, when the measurement was saved.
8.2. Data storage information
In the menu item "storage" you select „memory info“to get information about the actual
memory volume. The part of free memory, the total number of the stored sites and the
number of the measurements stored all together, split in the kind of the measurement is

8.6. Data transfer using the SD card
The data exchange format is CSV. A character-separated values (CSV) file is a simple text
format for a database table. Each record in the table is one line of the text file. Each field
value of a record is separated from the next by a character. Optima 7 uses a semi-colon ‘;’
as value separator (other implementations use sometimes a comma). Implementations of
CSV can often handle field values with embedded line breaks or separator characters by
using quotation marks or escape sequences. CSV is a simple file format that is widely supported, so it is often used to move tabular data between different computer programs, for
example Microsoft Excel™ or Access™, that support the format. Also other computer programs offer this type of interface because it is widely spread and easy to use.
The following functions are available from Software Version 1.11 and higher:
• Import of Sites
• Export of Sites
• Export of Flue Gas Measurements
• Export of Differential Pressure Measurements
Import of sites
With this function you can Import Sites which have been created on a computer or another
Analyzer.
The File name must have the name “anlagen.csv“(anlagen = german for sites). The file has
no column heading that means that the first line already has user data. Each line has a minimum of 9 columns (with 8 semi-colons) and the first field in the line will be the site number. All data will be imported as long a site number is available. Per field a maximum of 24
characters will be imported, too long words will be cut off.
Example file with 8 valid sites (4 with 9 lines and 4 with less lines):
A1-Z1;A1-Z2;A1-Z3;A1-Z4;A1-Z5;A1-Z6;A1-Z7;A1-Z8;A1-Z9
A2-Z1;A2-Z2;A2-Z3;A2-Z4;A2-Z5;A2-Z6;A2-Z7;A2-Z8;A2-Z9

Example file with 2 invalid sites (1 with not enough fields and 1 with missing site number):
A1-Z1;A1-Z2
;A1-Z2;A1-Z3;A1-Z4;A1-Z5;A1-Z6;A1-Z7;A1-Z8;A1-Z9
Important:
Whilst importing data from the SD Card to the analyzer there is no check for double site
numbers (Line 1), neither inside of the file that is imported nor between the file and the
sites already inside the analyzer. The analyzer can easily handle double site numbers but
36 / 51 MRU GmbH, D-74172 Neckarsulm
Page 37
Operation manual OPTIMA7
you could face problems with double site numbers when exporting them again to a computer program (see also Export of Measurements).
However the analyzer marks the files that have been imported successfully. If you try to import a file with the same analyzer that is already in the analyzer you will get a red information screen.
Export of sites
This function can be used for an analyzer back up or if you wish to supply the analyzer information to a computer program or another analyzer. This is very handy if you have made
some modifications inside the analyzer (site) for example if you have modified the phone
number of a customer and this modification needs to be updated in the computer software, or if a second analyzer needs to have the same site information.
The File format it’s the same as described above „Import of Sites“.
Only the file name is different, the file name will be ‚ANLxxxxx.csv’, in which the xxxxx are
continuing 5 digit numbers with leading zeros. If the file must be imported into another
analyzer, the file must first be renamed into “anlagen.csv”.
Export of Combustion Tests
This function is used to export the measurements from the analyzer to a computer program.
Attention! This function is not suitable for back up or for the transfer to another analyzer because
the exported file cannot be imported again!
The created file has the name ‚EMIxxxxx.csv’, in which the xxxxx are continuing 5 digit numbers
with leading zeros.
The created file has a column header with the following information: Site number, Date/Time,
Measuring program name, Fuel type, CO2max, O2reference, and all measured values that the analyzer can measure as well as the soot numbers, Derivate and T-Boiler.
Example:
Export of differential pressure measurements
The same function as Export of combustion tests only the file name is different.
The created file has the file name “DDMxxxxx.csv“, in which the xxxxx are continuing 5 digit numbers with leading zeros.

9 Extras / Adjustment
The OPTIMA 7 is delivered in a standard software configuration which should cover most
needs. However, there are many ways to tailor the settings to your individual needs if required. The possibilities are highly flexible and individual adaptable.
Use the variable possibilities to adapt your analyzer to your own needs and customize the
measurement menu, the measurement window, the printer output and many other features. Usually this is something you will do once you receive the analyzer, once you have
adapted your analyzer you will most probably don’t make much changes in future, but you
can whenever you need and want to do so.
After you have made any changes in the configuration, you should switch off the analyzer
to save all the changes that have been made. Next time that you start up the analyzer, all
changes will have been made.

9.4. Analyzer and accessories leak test
When performing the leak tight test, the complete system including the probe, the sample
line, the condensate separator and the analyzer are checked for leaks. The internal pump
will create a vacuum, this vacuum is measured at the pressure sensor and the result will be
displayed after 10 seconds of testing.
Performing the leak test
With the leak proof test the system is checked by the device (incl. the condensate separator) up to the probe spike on undensity. The internal gas pump generates in addition a sub
pressure which is measured over the built-in draft sensor and is observed for a period of 10
seconds. Based on the decrease of pressure the leakness of the system will be determined.
With dirt and soot particles on the probe tube the test cap will not seal properly
► The probe tip must be cleaned before you start this test!
Operation:
• The leak proof test cap # 61382 (for probe tubes Ø 8 mm) must be put on the probe
spike.
ATTENTION:
The probe spike before the density test clean!
(With depositions on the tube the cap does not
seal.)

10.3. Firmware update
Switch ON the device. Select F3 settings/Device info
OK The first line shows e.g.: Firmware-Version 1.33.00
For the case that there should be problems by the update we need some information of
you.
Please write down your Firmware-Version (e.g.
1.33.00)_________________________________
Please write down your serial number (e.g.
301231)_________________________________
You need the latest file 'All_1083.fwb'. In case you get it in a zip archive you have to extract
it before usage. This file contains all firmware types and the analyser will extract the correct
type out of this file automatically.
Please follow these steps in order to update the analyser:
• copy the file 'All_1083.fwb' to a SD card in the root directory (that means in no di-
rectory)
• switch on the analyser
• insert the SD card into the analyser
• in most cases a message 'Searching firmware, please wait...' will be displayed for
some seconds
• you will be asked: 'Firmware found. Install now?'
• acknowledge with 'install'
• for about 30 seconds the display will be dark, then the analyser will reboot with the
new firmware
• Finished
10.4. Using the USB Port
This port is used for data transfer from your analyzer to your PC / Laptop using the MRU
Online View (Version 2.XX). The first time you want to use your analyzer for data transfer to
your PC or laptop, you have to “mate” the OPTIMA 7 and your PC / Laptop.
Your PC / Laptop will recognize the OPTIMA 7 as USB- HID (Human Interface Device).
Check list:
1. Switch on the OPTIMA 7
2. Connect the USB cable to the OPTIMA 7
3. Connect the USB cable into a free USB port at your PC/Laptop
4. The PC/Laptop must be powered on
5. The above seen information „New hardware found“ will be displayed above the
USB-Icon of your PC/Laptop
