E.3 Basic operating steps
E.3 Basic operating steps
E.3.1 Connecting system components
Only a flue gas analyzer can be connected to the testo 350-S control unit. The
testo 350-M/XL control unit is required if several system components are to be
connected in parallel.
Connection using contact strips
1 Place the control unit on the flue gas analyzer so
that the guide nose on the left side of the control
unit () is above the guide groove of the flue gas
analyzer ().
2 Press the control unit against the flue gas analyzer
until you hear it engage.
Connection using a data bus cable (accessory part)
Use only Testo data bus cables . Do not lay data bus cables near power cables.
The data bus cable may not be disconnected under load
Connect the data bus cable to the Data sockets of the control unit and flue gas
analyzer.
Connection via Bluetooth
®
During first commissioning or if a connection to the standard analyzer is not possible,
the Control Unit searches for flue gas analysers in the vicinity.
- A flue gas analyzer has been found:
Flue gas analyzer and Control Unit are automatically connected, analyzer becomes
standard
- Several flue gas analyzers have been found:
The flue gas analyzers found are displayed for selection
- No flue gas analyzer found:
Error display
If a CAN connection exists, and the Bluetooth® standard instrument is not the one
currently connected, the vicinity will be searched.
For operation without mains connection, the Control Unit must be docked onto the
analyzer in order to switch on the unit. The control unit can then be removed.
Switching to Bluetooth®
- The unit automatically switches to Bluetooth® as soon as the Control Unit is separated
24
E. Operation
E.3 Basic operating steps
from the analyzer. An hourglass is shown during switchover. On completion, the display
goes out and an audible signal sounds.
- Switching over to a different analyzer during Bluetooth® operation.
Call up flue gas analyzer list and press function button Search.
- All analyzers are displayed.
Select desired instrument.
- After switching off, Bluetooth® remains switched on in analyzer (in mains operation
only), a new connection is thus possible at any time.
E.3.2 Switching the measuring system on
Before switching the measuring system on, check that:
· All system components are properly connected.
· All the necessary probes/sensors are connected.
· The power supply of all system components is guaranteed.
Measuring the ambient air temperature (AmbT)
If no ambient air temperature probe is connected, the temperature measured by the
thermocouple of the flue gas probe during the zeroing phase is used as the ambient air
temperature. All dependent parameters are calculated using this value. This method of
measuring ambient air temperature is sufficient for systems dependent on ambient air.
The flue gas probe should be near the intake duct of the burner during the zeroing
phase - not in the flue gas duct!
If an ambient air temperature probe is connected, the ambient air temperature is
measured continuously by this probe.
The flue gas probe can be in the flue gas duct even during the zeroing phase.
Zeroing phase
During the zeroing phase the measuring cells of the flue gas analyzer are zeroed. There
must be no interfering gases (e.g. CO, NO) in the ambient air during zeroing!
Switching on:
Press
.
- The initialisation screen is displayed and the data bus is scanned for connected
system components (this takes up to 60 s).
- The zeroing phase starts (this takes 60 s).
- Measurement view is opened.

called Noname.
On saving, readings are assigned to whichever location is active at the time of saving.
Several measurements can be saved for each location. It is also possible to organise
locations in folders/subfolders.
The maximum possible number of measurements that can be saved depends on
whether each individual measurement is saved under its own location or all
measurements are stored exclusively under one location.

E.5 Regular care
E.5 Regular care
E.5.1 Condensate trap / Condensate container
With gas preparation (GP, optional) fitted, the condensate is separated from the
measuring gas and is led into a condensate container that is isolated from the gas path.
In the case of longer measurements with moist flue gas, the condensate can be led off
using a tube without any external air being carried along.
On instruments without gas preparation, the measuring gas is led through a condensate
trap. This must always be kept closed during measurement so as to prevent external air
being drawn in.
The fill level of the condensate trap/condensate container is indicated by the markings.
Emptying the condensate trap/condensate container
The condensate consists of a weak mix of acids. Avoid contact with the skin. Make
sure that the condensate does not run over the housing.
Condensate entering the gas path.
Damage to the measuring cells and flue gas pump!
Do not empty the condensate trap/condensate container while the flue
gas pump is in operation.
1 Pull the condensate trap/condensate container ()
horizontally from the flue gas analyzer.
2 Open the drain plug () and allow the condensate
to drain into a sink.
3 Wipe off any drops still on the condensate outlet
using a cloth and close the condensate outlet.
4 Attach the condensate trap/condensate container
to the flue gas analyzer.

E.5.2 Checking/replacing the particle filter
Checking the particle filter:
Check the particle filter of the flue gas analyzer for contamination at regular intervals:
Check visually by looking through the window of the filter chambers.
Replace the filter if there are signs of contamination.
Replacing the particle filter:
The filter chamber may contain condensate.
1 Open the filter chamber: Turn the filter cover ()
anticlockwise and remove.
2 Remove the spent filter and replace it with a new
one (0554 3381).
3 Attach the filter cover and lock by turning it
clockwise. The cross part of the filter cover must
be aligned with the markings on the housing ().
E.5.3 Checking for system leaks
Check the measuring system for leaks at regular intervals. This will help to ensure
accurate measurement.
The leak test requires a plastic cap (0193 0039, comes with the flue gas probe). The
instrument must be switched on. A function key must be assigned the function Pstart
(start measuring gas pump), see Assigning function keys, p. 26. A display field of the
Measurement view must be assigned the parameter Pump (flue gas pump volumetric
flow rate), see Editing display, p.30.
- Measurement view is opened.

Recal.
CO, SO2, NO2, NO and O2 measuring cells can be tested and recalibrated; CO2(IR)
measuring cells can be recalibrated. A recalibration of O2 only lasts until zeroing is
performed. Calibration data are stored in the measuring cell, not in the instrument!
If obviously unrealistic readings are displayed, the measuring cells should be checked
and recalibrated as required. To ensure that specific accuracies are retained, Testo
recommends testing every six months and recalibration when required.
Dangerous gases
Danger of poisoning!
Observe safety regulations/accident prevention regulations when handling
test gases.
Use test gases in well ventilated rooms only.
38
F. Main menu
F.2 Sensors
Recalibration with low gas concentrations can lead to deviations in accuracy in the
upper measuring ranges.
Sensor protection (Switch-off function) is not deactivated in recalibration. The test gas
concentration should therefore be lower than the set thresholds for the sensor
protection.
The dilution function overall (x5) is automatically deactivated in recalibration.
If the instrument is fitted with an HC measuring cell, this should be switched off
before test gas is applied.
The following conditions must be met when recalibrating:
· Use absorption-free tube material
· Switch the measuring instrument on at least 20 min before recalibration (warming-up)
· Use clean air for gas zeroing
· Charge the test gas via calibration adapter (0554 1205, recommended) or the tip of
the probe
· Maximum overpressure of the test gas: 30 hPa (recommended: unpressurised via
bypass)
· Charge the test gas for at least 3 min
Recommended test gas concentrations and compositions are given in Testo's field
guide to test gases.
The recalibration function can be protected by means of a password. The password
may be customised, see Parameter, p. 41.
Performing CO2(IR) recalibration:
Zero point calibration must be performed before CO2(IR) is recalibrated. Gradient
adjustment (2nd calibration point) can be carried out subsequently if necessary.
Zero point calibration requires a test gas of 0 % CO2 or a CO2 filter (absorption filter). If
using a CO2 filter, please follow the corresponding instructions for use.

Dilution
The CO measuring range extension (optional) and dilution overall (x5) (fresh air valve
option) functions can be set. To enable measuring range extension for CO or dilution for
all measuring cells, the measuring gas is diluted with fresh air by means of a valve. This
results in a higher measuring range.
It is possible to choose various CO dilution factors between 2x and 40x. If the dilution
stage auto is selected, dilution (5x) is activated automatically when the set CO shut-off
threshold is reached. If overall (5x) is selected, all measuring cells are diluted (5x). The
measurement channels O2, CO2(IR), HC, CO2, qA, Lambda, Eta and all measurement
channels for flow velocity measurement are blanked out when dilution overall is selected.

G.1 Preparing measurements
G. Measuring
This chapter describes the measuring tasks that can be carried out with the product.
Familiarity with the contents of the chapter Operation (see p. 19) is assumed.
G.1 Preparing measurements
Setting the measuring system up:
Set the fuel of the combustion plant that is to be measured, see Setting fuel, p. 29.
Assign the necessary parameters and units of measurement to a display field in the
Measurement view, see Editing display, p. 30.
Activate the location to which the readings are to be assigned, see Setting locations,
p. 31.
Keeping gas outlets free:
When measuring, make sure that the gas outlets of the flue gas analyzer are exposed so
as to allow the gas to escape unhindered. Otherwise the measurement results may be
distorted.
Measurements with the HC measuring cell:
Gases that could form an ignitable mixture when exposed to air must not be measured:
Dangerous mixture of gases
Danger of explosion!
Always perform measurements in flue gas ducts.
There must always be sufficient oxygen in the flue gas to prevent the HC measuring
cell being destroyed. If the O2 content is less than 2 %, the HC measuring cell will
switch off automatically (safety function). Higher concentrations of silicones, H2S and
sulphurous hydrocarbons can also lead to the destruction of the HC measuring cell.
48
G. Measuring
G.2 Flue gas measurement
Zeroing takes place automatically when the HC measuring cell is activated ( HC On ). To
ensure that accurate HC readings are obtained, you should then wait about 10 min (with
the instrument switched on) before starting another zeroing process ( Zero ).
To prevent the HC measuring cell from drifting during lengthy measurement operations,
zeroing should be carried out occasionally ( Zero ).
G.2 Flue gas measurement
For a flue gas measurement to be performed, a function key must be assigned the
function PStart (start measuring gas pump), see Assigning function keys, p. 26.
A multi-hole probe is used to measure dCO (undiluted carbon monoxide).
After measurements involving high concentrations and long durations, the instrument
should be rinsed with fresh air so that the measuring cells can regenerate themselves
again, see the chapter Recommended rinsing times, p. 64.
Measuring:
1 Start measuring:
PStart
.
- The readings are displayed.
2 Stop measuring and record the readings:
PStop
.
G.3 Draught/differential pressure
measurement
For draught/differential pressure to be measured, a function key must be assigned the
function DeltaP (draught/differential pressure measurement), see Assigning function
keys, p. 26.
Measuring:
Do not measure for longer than 5 min, as a drift of the pressure sensor can result in
readings outside the tolerance limits.
Do not change between rechargeable battery and mains operation during the
draught/differential pressure measurement (voltage fluctuations influence the
measurement result)!
If you conduct the draught/differential pressure measurement after a flue gas
measurement, a head of pressure still exists in the hose after the pump has stopped.
It 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).
G. Measuring
49
G.4 Velocity measurement
When measuring the gas flow pressure of e.g. gas heaters:
Dangerous mixture of gases
Danger of explosion!
Make sure there are no leaks between the sampling point and the
measuring instrument.
Do not smoke or use naked flames during measurement.
1 Depressurise pressure inputs (ambient pressure).
2 Start the measurement:
DeltaP
.
- The pressure sensors are zeroed.
3 Pressurise the pressure inputs.
- The readings are displayed.
4 Stop measuring:
.
- If a display field is assigned the parameter DeltaP, the reading is copied into the
Measurement view.
G.4 Velocity measurement
For a velocity measurement to be performed, a function key must be assigned the
function V On (velocity measurement), see Assigning function keys, p. 26. For the
readings to be displayed, a display field must be assigned the necessary velocity
parameter (Spd, Vol, MCO, MSO2, MNOx). A temperature probe must be connected to the
flue gas temperature probe input.
For correct measurement results, the parameters Pres., Pitot factor, Cross section and
Dew point/ambient air (if calculating the mass flow) must be set. Flow velocity
measurement can be carried out parallel to exhaust gas measurement.
Measuring:
Do not measure for longer than 5 min, as a drift of the pressure sensor can result in
readings outside the tolerance limits.
1 Depressurise pressure inlets (ambient pressure).
2 Start the measurement:
v On
.
- The pressure sensors are zeroed.
3 Pressurise pressure inlets/insert the Pitot tube into the flow duct.
- The readings are displayed.
4 Stop measuring and record the readings:
v Off
.
50
G. Measuring
G.5 differential temperature measurement
G.5 Differential temperature
measurement
In order to carry out a differential temperature measurement, a function key must be
assigned the function deltaT, see Assigning function keys, p. 26.
Carrying out measurement:
1 Start measurement: deltaT .
- The measurement values are displayed (T1 = FT, T2 = AT, deltaT = T1 - T2).
2 End measurement and freeze readings: OK .
G.6 Measurement program/solid fuel
measurement
The solid fuel measurement program is only available with instruments equipped with the
measurement range extension CO option of a CO measurement cell (not COlow) and
gas preparation.
For a measurement program/solid fuel measurement to be performed, a function key
must be assigned the function Start (start measurement program/solid fuel
measurement), see Assigning function keys, p. 26.
Draught, differential pressure and velocity readings cannot be determined within one
measurement program.
The measurement program/solid fuel measurement must be activated, see Program,
p. 35.
Measuring:
testoterm
1
Insert flue gas probe (with probe pre-filter) into the flue gas pipe and
position in the core flow
2
Start pump
-
Observe measurement values until the O2 < 20 %, in order for values
to be calculated
3
PStart
Start measurement program / solid fuel measurement: Start
(without flushing phase).
- The measurement program/solid fuel measurement runs until the set end criterion
(15 min/ 900 measurement values) has been reached. This is always followed by a
rinse phase (duration: 2 min).
H. Care and maintenance
51
H.1 Cleaning the measuring instrument
- The measurement program/solid fuel measurement remains active even after the
program has come to an end.
Deactivate the measurement program/solid fuel measurement, see Program,

Назначение блока анализатора дымовых газов testo 350-S/-XL

testo 350 является гибкой портативной системой анализа дымовых газов, состоящей из блока анализатора и управляющего модуля в двух версиях: testo 350-S (базовая версия) и testo 350-XL (расширенная версия). Блок анализатора дымовых testo 350-S снабжен сенсором O2, функцией измерения дифференциального давления, 2 гнездами для зондов температуры, разъемом для соединения с шиной данных Testo, встроенным аккумулятором, логгером данных. Можно установить максимум 6 измерительных модулей по выбору (CO, NO, NO2, HC, SO2, H2S или CO2 NDIR (инфракрасный сенсор)). Расширенная версия анализатора, testo 350-XL, снабжена всеми функциями testo 350-S с дополнительными особенностями — в блок уже встроенны: сенсоры CO (с функцией отключения и продувки), NO, NO2, блок пробоподготовки Пельтье, автоматическая продувка свежего воздуха через клапан (вкл. расширение диапазона измерений с коэффициентом разбавления 5 для всех сенсоров), память.

Анализатор testo 350-S может быть дооснащен всеми функциями анализатора testo 350-XL. Модели прибора внесены в Государственный Реестр Средств измерений РФ.
