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

Name
Description/Function
1
Sample 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.
2
Auxiliary Port Used with a sample conditioning probe, if chosen as an
option.
3
Pressure 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.
4
Stack
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.
