1. INTRODUCTION
Congratulations on buying your Tempest 50 combustion
performance analyser. The unit has been carefully designed and
includes the latest technology to give you an instrument that is easy
to use, reliable and accurate.
The Tempest 50 is part of a new family of instruments from
Telegan, a company with over 15 years of combustion
instrumentation experience. It measures the oxygen (O2) and
carbon monoxide (CO) content of tested flue gas and the flue,
ambient, inlet and nett temperatures. It calculates the carbon
dioxide (CO2) content of the flue gas as well as the nett or gross
percentage boiler efficiencies for a wide range of different fuels.
The Tempest 50 is rugged and has been designed for a tough life
with heating professionals. Its wipe-clean touch panel allows you
to achieve the results you need quickly and simply, without the risk
of moisture or dust damaging the contents. As you will see from
this manual, much of the instrument’s operation can be done with
just three buttons.
Several options are available with the TEMPEST 50. These can be
specified for delivery with the instrument or can be added later.
They include a built-in printer, pressure/draught measurement,
nitric oxide (NO) measurement and total nitrogen oxides (NOx)
calculation, display back-light and RS232 output for other devices.
If you would like to add any of these options please contact our
sales office (see back cover for details).
This manual will show you how to get the best out of your new
TEMPEST 50. Section 3 shows you the layout of the instrument.
Go straight to Section 4 to start using your TEMPEST 50. If you
have any questions please contact us. Thank you very much for
buying our product -we wish you many years of successful use.

3. TEMPEST GRAND TOUR
This chapter describes the layout of the TEMPEST 50 unit and gives a
brief introduction to the physical and electrical connections, the keypad
details and functions and the various output devices which include the
display, printer and indicator lights. The top panel is broadly divided into
three sections as follows:
Left: Physical Connections which include the various ports and
thermocouple sockets.
Centre: Control Panel which includes the keypad layout, display and
indicators.
Right: Printer and Communications Ports which includes the printer,
charger input socket and the communications ports.
3.1 Left: Physical Connections
This section shows how to connect the sampling probe, thermocouples
and other accessories to the TEMPEST 50 unit. Please refer to Figure 1
for the following reference numbers.
Ref
No
Name
Description/Function
1Sample Port The port through which the sample gas to be analysed
must pass. The sample line from the probe should be
fitted to the spigot of the sampling port for emissions
measurement.
2Auxiliary Port Used with a sample conditioning probe, if chosen as an
option.
3Pressure Port The sample line from the probe should be fitted to the
spigot of the pressure port for pressure/draught
measurement, if chosen as an option.
4Stack
Thermocouple
Socket
Socket for the thermocouple plug attached to the
sampling probe. When connected the TEMPEST 50
will measure the temperature at the tip of the probe.
5. Intake
Thermocouple
Socket
Socket for a thermocouple plug that may be attached to
an auxiliary thermocouple placed in the intake gas
stream. If this is not fitted a spot measurement of the
temperature of the intake gas may be measured using
the standard sampling probe.
6. Vent Auxiliary vent for use with the sample
conditioning probe.
3.2 Centre: Control Panel
This section details the control panel area which is used to operate the
TEMPEST 50 unit. It incorporates a keypad, display and various
indicators (Refer to Figure 2 Centre : Control Panel).

Name
Description/Function
7Power On/Off Keys These two keys must be pressed
simultaneously to switch the unit on and off.
This prevents the unit from being turned off
accidentally during operation.
8Battery Recharge
Indicator An illuminated green LED next to the battery
symbol indicates that the internal battery is
being charged by an external power source.
9Power Indicator An illuminated red LED next to the on/off
symbol indicates that the unit is switched on
and receiving power from either the internal
battery or an external power source.
10 Display The area where all the information regarding
the current mode of operation of the
TEMPEST 50 is displayed.
11 Keypad Allows the operator to control the unit and
access the TEMPEST 50 functions using
simple keystrokes. The positions of the
principal keys are shown in Figure 2 and a
tabulated brief description of their functions is
given in Table 1 : Quick Key Reference
(centre page).
3.3 Right : Printer and Communications
This section describes the physical layout of the integral printer (if
fitted as an option), the charger input socket and the various
communications ports used to send emissions data to external
devices (Refer to Figure 3 Right : Printer and Communications
Ports).
No. Name Description/Function
12 Printer Cover Protects the printer unit from damage
while allowing easy access for
replacement and insertion of the
printer roll and ribbon
13 Paper Slot The printer paper roll should be fed
through the paper slot which also acts
as a sharp cutting edge to tear the
paper.
14 Printer Cover
Catch Click-tight catch that holds the printer
cover in place.
15 RS232 Port If chosen as an option, the RS232
communications port allows the
TEMPEST to send emissions data to a
suitable terminal or data logging
hardware.
16 Charger Socket Receiving socket for either the mains
charger or the 12V DC charger.
17 Parallel Port Performs no function for the
TEMPEST 50. An additional
communications port for higher
specification units.
