3.1. Use
Do not use the testo 350 MARITIME for continuous flue gas measurements, i.e. the sensors must be regularly rinsed with fresh air. Recommended measurement periods and rinse phases, see Recommendation for emissions measurements over an extended period of time, page 89.The testo 350 MARITIME is a portable
flue gas analyser, which can be used as a system component within a complete monitoring system to measure flue gas emissions from marine diesel engines in accordance with MARPOL 73/78 Annex VI and NOx Technical Code 2008 (MEPC.177(58)). In order to fully comply with the on-board detection procedure of the “Direct Measurement and Monitoring Method” MARPOL 73/78 Annex VI and NOx Technical Code 2008 (MEPC.177(58)), additional parameters must be recorded.
The testo 350 MARITIME has been designed for the following applications:
• The testo 350 MARITIME can be used as a system component to measure the gaseous flue gas concentrations of O
2
, CO,
CO
2
, NOx and SO2for the following procedures:
• for periodical examinations and for intermediary
examinations for direct measurement and monitoring on board
• as a component for a simplified test and measuring method
(HC must be measured separately
• testing the NOx limits specified in MARPOL Annex VI for official NOx monitoring measurements on board.
• NOx measurement as proof in regional special zones, e.g. as proof of NOx reduction for NOx tax in Norway
The flue gas analyser testo 350 MARITIME is certified by DNV GL for measuring gaseous flue gas components as a system component (e.g. for the “direct measurement and monitoring” on board procedure, and for simplified measurement procedures).
Other system components required in accordance with NOx Technical Code for the “direct measurement and monitoring” on board procedure are not included in this certification!

A readjustment of O2 only lasts until another zeroing is carried out or the testo 350 MARITIME is switched off. Calibration data is stored in the sensor, not in the instrument! The relevant calibration instructions of the standards/guidelines to be applied must be followed (e.g. calibration or adjustment of the gas sensors before and after a flue gas measurement).
If obviously unrealistic readings are displayed, the measuring cells should be checked and readjusted as required. To ensure that specific accuracies are retained, Testo recommends testing every 3 months and readjusting when required.
Adjustments made with low gas concentrations can lead to accuracy deviations in the upper measuring ranges.
The sensor protection (shut-down function) is not deactivated. The test gas concentration should therefore be lower than the thresholds set for the sensor protection.
The following boundary conditions must be met when calibrating / adjusting:
• Use absorption-free hose material.
• Select Test gas fuel.
• Switch on the flue gas analyser at least 20 minutes before calibration / adjustment (to warm up)
• Use clean air for gas zeroing
• Maximum overpressure of the test gas 30 hPa (recommended: pressureless via bypass)
• Apply the test gas for at least 3 minutes
Recommended test gas concentrations and compositions can be found in the Testo Test Gas Manual (order no. 0980 2313 version D) or in the Download Centre.

6.2. Measuring
6.2.1. Preparing for measurement
The fresh air required for the zeroing phase is sucked in via the valve inlet. The flue gas probe can therefore already be inside the flue gas channel before or during the zeroing phase.
If no combustion air temperature probe is connected, the temperature measured by the thermocouple of the flue gas probe during the zeroing phase is used as the combustion air temperature. All dependent parameters are calculated using this value.
The testo 350 MARITIME can be operated as follows:
• lying down
• hanging down horizontally by its handle
Page 57
6 Using the product
57
• plugged vertically to the wall bracket by the handle To prevent measuring errors, the position of the testo 350
MARITIME must not be changed during a measurement.
Under ambient temperatures of <10°C the CO2(IR) sensor requires a shorter warm-up period to reach full measuring accuracy. At -5°C this typically is 15min.
Before switching on
> Check whether:
• All system components are properly connected.
• All required probes / sensors are connected.
• The power supply of all system components is guaranteed.
During the zeroing phase
During the zeroing phase, the sensors of the flue gas analyser are zeroed. Zero point and drift of the sensors are checked. The O
2
value is set to 21% O2. > Make sure that the ambient air is free of interfering gases (CO,
NO, etc.) during the zeroing phase!
Before the measurement
> Set the fuel for the engine to be measured. > Activate the location to which the readings are to be assigned. > Enter the ambient temperature (tAin) and ambient humidity
(hAin) at the turbocharger inlet.
> If necessary, calibrate or readjust the sensors (observe country-
specific regulations)
> Make sure that the gas outlets are free, so that the gas can
escape without obstruction. Otherwise the measurement results may be corrupted.

6.2.2. Position flue gas probe
6.2.2.1. Flue gas flow with hot spot characteristics
㾐 The tip of the probe must be in the hot spot of the flue gas.
> Align the flue gas probe in the flue gas duct so that the tip is in
the area of the highest flue gas temperature.
Do not measure within the marginal area. Measure min. 3x diameter of the flue gas boiler away from the last elbow.

ᶉ Handle
ᶊ Flue gas duct
The immersion depth depends on the insulation thickness of the flue gas duct. If the flue gas is measured directly downstream of the flue gas turbocharger, the flue gas is very homogeneous in the flue gas duct due to good mixing, i.e. there is no hot spot. There is therefore no need to precisely position the probe shaft.
6.2.3. Attachment options for the flue gas probe
WARNING
To prevent damage to the instrument, the engine system and personnel, special measures must be taken when attaching the flue gas probe if there is powerful vibration of the flue gas duct. If the probe stop is simply screwed in, the attachment will not remain durable or leaktight if there are strong vibrations.
> Position the probe so that no damage can be done to the
engine system if the flue gas probe's attachments fall off or if the probe is broken.
> Only leave the flue gas probe in the flue gas duct for the
duration of the measurement. Once the measurement has been completed, remove the probe from the flue gas duct.
> For the probe to be adequately attached, the free-floating end
of the probe must also be suitably fixed in place / supported. Otherwise there is a risk that the probe will break.

6.2.5. Flue gas measurement
Depending on the country-specific legal requirements, the flue gas analyser must be calibrated or readjusted before the measurement (max. 6-8 hours beforehand). Follow the calibration instructions prescribed in MARPOL Annex VI and NOx Technical Code 2008.
A selected load point (in accordance with NOx Technical Code
2008) must be kept stable for the measurement. Start the flue gas measurement once the load point is stable.
The flue gas menu (Measurement Type) is the central measuring menu, which – in addition to the readings measured with this function – contain the readings of all measurements carried out (if selected in the menu Measurement view). All readings can also be saved in or printed out from these menus.
Measuring functions of the flue gas menu:
• The measurement type Flue Gas can be used to carry out a
flue gas measurement.
After measurements with high concentrations and after longer measurements, the instrument should be rinsed with fresh air, so that the sensors can be regenerated again.
Call up function:

In order to maintain the measuring accuracy of the instrument, the correct fuel, or the user-configured fuel, must be selected.
To calculate the flue gas values correctly in accordance with NOx-TC and MEPC.103(49), the ambient humidity/temperature of the turbocharger's intake air must be taken into account. The following values are stored as the factory setting:
• Ambient humidity: 50% RH
• Ambient temperature: 25°C

6.2.6. Differential pressure measurement (determining the pressure in the flue gas duct)
Do not measure for longer than 5 min, as the drift of the pressure sensor means that the readings could be outside the tolerance limits. Do not switch between battery and mains operation during the differential pressure measurement (voltage fluctuations influence the measurement result)!
If you conduct the differential pressure measurement after a flue gas measurement, a head of pressure still exists in the hose after the pump has stopped, which must be dispelled.
This occurs within approx. 30 seconds. Remove any traces of condensation in the flue gas probe (shake out the probe with the tip towards the floor).

6.3. Analog outputs
(only available via tab Analog output box)
The analog output box is displayed like the meas. box. The tab contains the databus number.
The analog output unit 0554 3149 (accessory) is suitable for the output of up to 6 measuring channels in the form of analog signals (4 to 20mA). The analog output unit is connected to the instrument via data bus, and the configuration can be carried out via the control unit.
Power supply
Power is supplied to the analog output box via the measuring box. The LED of the analogue output unit lights green when the power
supply is correct. Each individual output channel is thereby assigned to a measuring
channel, the range of the respective measurement channel is entered and then corresponds to the 4 t 20 mA output of the output box connected to this channel. If the measurement range is exceeded 21-22 mA is still output, depending on load. If the
Page 66
6 Using the product
66
measurement range is fallen short of, the output will be up to 3.5 mA.
The current value is set to 3.5 mA as start value for a non-adjusted analog output box and for cases of faults.
Connections
The channels are electrically isolated towards the Testo databus. However, the individual channels are not electrically isolated among each other.
When connecting you must make sure that there are no undesired ground loops!
In both channels the positive output is connected to the ground connection of the recorder. The interfaces work correctly.

8.3. Updating the instrument software
At www.testo.com/download-center you can download the current instrument software (Firmware) for the testo 350 MARITIME (registration required).
Control unit and measuring box must be disconnected in order to update the instrument software.
Before starting the firmware update, the rechargeable battery for the control unit must be fully charged. A rechargeable batter that is not fully charged will result in a faulty firmware update. If that happens, the flue gas analyser must be sent off to the Testo Service team.
Once the instrument software has been updated, it is possible that the descriptions in the instruction manual and the instrument functions no longer match up. You can find an up-to-date instruction manual at www.testo.com\download-center.
