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
