Ensure safety> Only operate the product properly, for its intended purpose andwithin the parameters specified in the technical data. Do not
use any force.
> Do not operate the instrument if there are signs of damage at
the housing, mains unit or feed lines.
> Do not perform contact measurements on non-insulated, live
parts.
> The flue gas analyzer is not suitable for long-term
measurements and should not be used as a safety (alarm)
instrument.
> Do not store the product together with solvents. Do not use any
desiccants.
> Carry out only the maintenance and repair work on this
instrument that is described in the documentation. Follow theprescribed steps exactly. Use only original spare parts
from Testo.
>

Any further or additional work must only be carried out by
authorised personnel. Testo will otherwise refuse to accept
responsibility for the proper functioning of the measuring
instrument after repair and for the validity of certifications.

> Only use the device in closed, dry rooms and protect it from rain
and moisture.
> Temperatures given on probes/sensors relate only to themeasuring range of the sensors. Do not expose handles andfeed lines to any temperatures in excess of 70 °C unless they
are expressly permitted for higher temperatures.

2 Safety and the environment>

The flue gas analyzer must be checked before
commissioning for any visible damage. Do not commission
the flue gas analyzer if there are signs of damage on the
housing, mains unit or supply lines. Electrical risk.

> Dangers may also arise from the systems being measured or
the measuring environment: Note the safety regulations valid inyour area when performing the measurements.
Use distilled water, or alternatively mild solvents such as
isopropanol to clean the flue gas analyzer. If using
isopropanol, please refer to the instruction leaflet for the
product. Isopropanol fumes have a slight narcotic effect,
and typically cause irritation of the eyes and sensitive
mucous membranes. When using it, please ensure that
there is adequate ventilation.
Do not store any objects that have come into contact withsolvents and/or degreasers (e.g. isopropanol) in the case.
Evaporating or leaking solvents and/or degreasers may
cause damage to the instrument and to the sensors.
The use of strong or harsh alcohol or brake cleaner can
result in damage to the instrument.
For products with Bluetooth® (optional)
Changes or modifications that have been made without the explicit
consent of the responsible approval authority, may cause theretraction of the type approval.
Data transfer may be disturbed by equipment that uses the same
ISM-band, e.g. WLAN, microwave ovens, ZigBee.
The use of radio communication links is not permitted, among
others, in aeroplanes and hospitals. For this reason the following
points must be ensured before entering:> Switch off the device:> Isolate the device from any external power sources (mains
cable, external rechargeable batteries, ...).

Product-specific safety instructions
CAUTION
Acid in the sensors.
May cause chemical burns.
> Do not open the sensors.
Eye contact: Rinse the affected eye thoroughly under runningwater for 10 minutes, keeping the eyelids wide open andprotecting the unaffected eye. Remove contact lenses
wherever possible.
CAUTION
Powder in the sensor filters.
May cause irritation to the skin, eyes or respiratory tract.
> Do not open the sensor filters.
Eye contact: Rinse the affected eye thoroughly under runningwater for 10 minutes, keeping the eyelids wide open andprotecting the unaffected eye. Remove contact lenses
wherever possible.
Skin contact: Remove the injured person’s contaminatedclothing, ensuring self-protection. Rinse affected skin areas
under running water for at least 10 minutes.
Inhalation: Move to fresh air and make sure that breathing isunrestricted.
Ingestion: Rinse mouth out and spit out liquid. If conscious,
drink 1 glass of water (approx. 200 ml). Do not induce vomiting.
ATTENTION
Deep discharge of the battery cell
Damage to the battery cell due to deep discharge,
replacement required!
> Due to minimal power consumption of the sensor system evenwhen switched off, the instrument must not be stored for long
periods with an empty battery (< 30% capacity remaining).
Prior to long storage periods (e.g. over the summer season),the rechargeable battery must be charged to at least 30-50%.

Use
The flue gas analyzer is a handheld measuring device for the
professional flue gas analysis of combustion plants:• Small combustion plants (burning oil, gas, wood, coal)
The solid fuel measurement adapter (0600 9765) isrequired for measurements on solid fuel systems. The
adapter protects the measuring instrument from harmful
substances (dust, organic compounds, etc.).
• Low-temperature and condensing boilers• Gas water heaters
These systems can be adjusted using the flue gas analyzer andchecked for compliance with the applicable limit values.
The following tasks can also be carried out with the flue gas
analyzer:• Regulating the O2, CO and CO2 values in combustion plants
for the purpose of ensuring optimal operation.
• Draught measurement.
• Measuring and regulating the gas flow pressure in gas water
heaters.
• Measuring and optimising the flow and return temperatures ofheating systems.
• Ambient CO measurement (only possible with additional
ambient CO probe 0632 3331).
• Ambient CO measurement (only possible with additional
ambient CO probe 0632 1240).
• Detection of CH4 (methane) and C3H8 (propane) (only possible
with additional gas leak probe 0632 3370).
The Bluetooth® option may only be operated in countries in which it
is type approved.

Mains operation

If the mains unit is connected, the measuring instrument is
automatically powered from the unit.
1. Connect the mains unit instrument plug to the instrument's

Testing for leaks

6.2.1.2.

Zeroing phases

The entire measurement system (probe, condensate trap, hoses
and connections) must be tested for leaks before eachmeasurement to avoid incorrect measurements due to theinfiltration of external air. Testing is carried out while the pump is
running and may be performed by attaching a compressed balloon
pump. The measurement system is leak-tight if the balloon pump is
not filled with air.

Measuring the combustion air temperature
If no combustion air temperature probe is connected, during thezeroing phase, the measured temperature of the flue gas probe istaken as the combustion air temperature.
The flue gas probe should not be in the flue gas duct
during the zeroing phase.
All dependent parameters are calculated using this value. Thismethod of measuring combustion air temperature is sufficient forsystems dependent on ambient air.
If a temperature probe is connected, the combustion air
temperature is measured continuously via this probe.
Gas zeroing
When the instrument is switched on, the measurement menu is
opened and the gas sensors are zeroed.
The flue gas probe must be in fresh air during the zeroingphase!
Draught/pressure zeroing
The pressure sensors are zeroed when a pressure measuringfunction is called up.
The flue gas probe must be in the fresh air during thezeroing phase / the instrument must not be pressurised
during zeroing.

7.1.

Maintaining the productCleaning the measuring instrument> If the housing of the measuring instrument is dirty, clean it witha damp cloth. Do not use any aggressive cleaning agents orsolvents! Mild household cleaning agents and soap suds may
be used.
Use distilled water, or alternatively mild solvents such as
isopropanol to clean the flue gas analyzer. If using
isopropanol, please refer to the instruction leaflet for the
product. Isopropanol fumes have a slight narcotic effect,
and typically cause irritation of the eyes and sensitive
mucous membranes. When using it, please ensure that
there is adequate ventilation.

IMPORTANT
Leaking solvents and degreasers!
Damage to the instrument and sensors!
The following substances can damage the instrument or the sensors:• Solvent-containing vapours such as those contained in cleaning agents,
degreasers, wax polishes and adhesives• Formaldehyde
Do not store cleaning cloths, solvents and degreasers, such as isopropanol,in the case.
IMPORTANT
Strong or harsh alcohol or brake cleaner!
Damage to the instrument!
- Do not use any strong or harsh alcohol or brake cleaner.

> Unplug the micro USB cable and switch off the flue gas
analyzer.
1. Hold down [▲].
2. Reconnect the micro USB mains cable to the flue gas analyzer,
continue holding down [▲].
- The display shows Firmware update along the bottom edge.
3. Release [▲].
- Your PC recognises the flue gas analyzer as a removablemedium.
