3.1 Turning On
Always: - Before turning on please ensure
that the In-Line Pump Protection Filter
(shown across) is connected to the Gas
Sample Port (see 2.2 or 2.4).
**THIS MUST REMAIN ON THE UNIT
AT ALL TIMES.**
Failure to do so may result in pump failure
and will invalidate the warranty.
Press the Power Key for approximately 2 seconds and the TPI 712 will start
up and display ALL Segments on the display for approx. 1 second. The 712 will
then enter its 30-second purge period countdown with the following screen being
displayed.
The instrument should ALWAYS be turned on
in a clean air environment as the 30 second
purge will attempt to set the Carbon Monoxide
level to 0 ppm and the Oxygen to 20.9%.
If there is insufficient clean air in the sensor
chamber after the 30 second purge period an
error indicating this may be displayed, please
see troubleshooting guide (appendix D) for
appropriate remedy. If the error is still present
after attempting the suggested remedy please
call the
TPI HELPLINE
01293 530196
3.2 Fuel Selection
During the last 20 seconds of the 30 second purge time (i.e. as the 712 counts
down from 19 to 0) the user can scroll through the following Fuels: - Natural Gas,
LPG, Light Oil, Heavy Oil & OPT 1-6 (1=Bituminous Coal, 2=Anthracite Coal,
3=Coke, 4=Butane, 5=Wood(Dry) & 6=Bagasse) by repeatedly pressing the
Up Arrow Key to select the Fuel they are working with.

4. THE 5 FUNCTIONS
After the 30-second countdown the instrument is ready to take Flue Gas,
Temperature, Pressure or Leak Detection readings and will Display the
following Screen.
You are now ready to take Flue Gas Analysis
Readings. Please continue on with the manual from
Section 4.1 (below) which will guide you through the
various Analysis Screens.
However, if you do not wish to perform a Flue Test at
this moment Press the Func/Backlight Key
and move onto Section 4.2 of the manual.
At any time you can activate the Backlight by holding down the
Func/Backlight Key for 2 seconds.
4.1 Function 1: - Flue Gas Analysis
Ensure you have connected the Temperature Sampling Probe complete with
In-Line Water Trap Bowl Filter to the In-Line Pump Protection Filter (See 3.1)
which should ALWAYS be connected to the Gas Sample Port (see 2.2 or 2.4)
and that the ‘K’ Type Thermocouple Plug is in Thermocouple Socket (ch1)
(see 2.4). Also ensure that a ‘K’ Type Air Probe is connected to
Thermocouple Socket (ch2) (see 2.4) in order to calculate efficiency.

Your temperature-sampling probe comes complete with an In-Line Water Trap
Bowl Filter as standard.
This consists of a Particle Filter in the
Bowl Compartment and a Disc Filter
in the Lid (as shown in the diagram
across). The Disc Filter in Lid will
prevent any excessive water from
entering the 712 Flue Gas Analyser if
used correctly.
If you are working with OIL then you MUST ensure that you also use the optional
Oil Filter as shown below. Failure to do so will result in erroneous readings.
If any of the filters become excessively dirty or blocked then the
following screen will be displayed as a warning and no further
readings will be able to be taken until either the dirty filters are
replaced or the blockage removed:-
The 712 will also give off an audible Beeping Alarm
to warn that a “FLo Err” is being detected

WARNING: - Ensure that the In-Line Water Trap Bowl Filter hangs in a vertical
position whilst readings are being taken, particularly if water is visible (see below).
Failure to comply may result in damage to the instrument and will invalidate
the warranty.
WARNING: - There is ONLY one correct way to connect the
‘K’ type thermocouple plug into the socket (see 2.4). The
thermocouple plug is designed with one thick (negative) and
one thinner (positive) prong. Forcing the plug into the socket
the wrong way round may result in damage to the instrument.
Failure to comply may result in damage to the instrument
and will invalidate the warranty.
Pressing the Scroll/Enter Key will take you through the following Flue Gas
Analysis Screens
4.1.1 Screen 1
Displays Carbon Monoxide (CO) reading in parts per
million (ppm)
Displays calculated Carbon Dioxide (CO2) figure in
percentage (%)
Displays calculated CO/CO2(Ratio) figure

4.1.2 HIGH CO ALARM
Should the CO reading rise above 2,000ppm a continuous series of Alarm Beeps
will be heard. If this occurs then the Probe should immediately be disconnected
from the instrument and the instrument returned to a clean air environment. This
Alarm alerts the user that there is a high concentration of CO, and this procedure
will protect the sensors within the instrument.
Failure to comply may result in damage to the instrument and will invalidate
the warranty.
4.1.3 Screen 2
Displays Oxygen (O2) reading in percentage (%)
Displays calculated Excess Air (X Air) figure in
percentage (%)
Displays calculated Efficiency (Eff.) figure in percentage
(%)
Pressing the Up Arrow Key will toggle between
Gross & Nett Efficiency
4.1.4 Screen 3

million (ppm)
Displays Oxygen (O2) reading in percentage (%)

4.1.5 CO Build Up Feature
Whilst on Screen 3 of the Combustion Screens (see 4.1.3) press and HOLD the
Store/Logger Key until the 712 beeps and the following screen is
displayed:-
“S-L9” will be flashing. Press the Scroll/Enter Key
and choose an address location by pressing the
Up & Down Arrow Keys.
When an address location (0-4) has been
chosen press the
Scroll/Enter Key to start the CO
logging session.
The 712 will return to the previous screen and “Logger” will be flashing at the top
of the display. The instrument will now log the CO level every minute for the next
30 minutes and store the results in the chosen address location.
You can end the CO logging at any point by pressing and holding down the
Store/Logger Key.
Both the Maximum and Average CO readings will be stored during this test.
These readings can then be either Printed to a compatible IR Printer (see 7) or
Downloaded to a compatible PC (see 9)

degrees Centigrade (ºC)
Displays the Differential Temperature (Diff.) between ch1
and ch2 in ºC
‘oPEn’ will be displayed if no ‘K’ type probe is
connected to the thermocouple socket
4.1.8 CO above 15ppm (Failsafe) Protection Beep
The 712 will not allow the user to either Turn the instrument OFF or to move to
another Function whilst the CO level is above 15ppm. A short beep will be heard
should the user attempt either of the above with the CO above 15ppm.
This is a Failsafe Feature of the 712 to protect the instrument from giving false
readings when next turned on. The 712 should be run in a clean air environment
with just the In-Line Pump Protection Filter attached until the CO level drops
below 15ppm. The 712 will then be able to be moved to a different function
screen or be turned OFF.
