This section contains similar information to the thermometer
Installation Guide.
If the thermometer is to be used in conjunction with a protection jacket and
air purge, refer to the installation guides provided with those accessories.
If the thermometer is to be installed in a location where the ambient
temperatureiswithintherangesspeciedforthethermometer,andnoair
purging is required to keep the lens clean, the thermometer can be mounted
using the two tapped holes on the mounting pad. Either hole can be used for
direct tripod mounting.
2.1 Choosing a location for the thermometer
The overall dimensions of the thermometer installation are given in Fig. 4.
1) Choosealocationwherethethermometerwillnotbeexposedto 
 excessiveheat,fumesandspray.
 Refertothe‘Specication’(Page3)forambienttemperaturelimitsetc.
2) RefertotheTargetSizeTable(Fig.3).Ensurethatthetargetcompletely
 llstheeldofviewatthechosentargetdistance.
Check that nothing obstructs the sighting path between the thermometer
and the target.
3) Makesurethatthesightingpathisfreefromsmoke,oilorwaterspray.
4) Ensurethatthechosenlocationforthethermometerallowseasyaccess
for servicing.
2.2 Power supplies and temperature displays
The FLT5A Thermometer requires a power supply of 12 to 48V d.c.

3 Using the Thermometer
It is recommended that the 'Emissivity' and 'Response Speed' controls are
set to match the requirements of the particular measurement location before
installation. This is particularly relevant if the thermometer is to be used in a
locationwhichisdifculttoaccessand/orusedinconjunctionwithajacket
and back cap.
3.1 Location of controls
The 'Emissivity' and 'Response Speed' control switches are located on the rear
face of the thermometer. The controls are protected by a screw-on cap
(SeeFig.5).
NOTE
To keep the thermometer electronics sealed against ingress
of dust and moisture, always replace the screw-on cap after
adjusting the settings.
3.2 Adjusting the 'Emissivity' value
For accurate temperature measurement, the 'Emissivity' setting must be set
to correspond with the target being measured.
The emissivity can be set in the range 0.10 to 1.09 in steps of 0.01.
The FLT5A is supplied with the emissivity factory-set to 1.00.
The 'Emissivity' value is set using switches SW1 and SW2. See Fig. 6.
When switch SW1 is set from 1 to 9, this denotes the rst gure after the
decimal point of the emissivity value.
e.g. for an emissivity value of '0.85', set SW1 to '8' and SW2 to '5'.
When switch SW1 is set to 0, this denotes a '1' before, and a '0' after, the
decimal point of the emissivity value.
e.g. for an emissivity value of '1.00', set SW1 to '0' and SW2 to '0'.

3.3 Adjusting the averager 'Response Speed'
The Averager time function is adjusted by the potentiometer P1.
(SeeFig.6,Page6).
The Averager 'Response Speed' can be set to any value between 1 and 10
seconds(for0to95%ofnalreading).
1) Toincreasethe'ResponseSpeed'(i.e.makefaster),turnthe
potentiometer P1 anticlockwise. When P1 is turned fully anticlockwise, the
'Response Speed' is 1 second.
2) Todecreasethe'ResponseSpeed'(i.e.makeslower),turnthe
potentiometer P1 clockwise. When P1 is turned fully clockwise, the 'Response
Speed' is 10 seconds.
3.4 Note your settings
Write down the settings for 'Emissivity' and 'Response Speed' in the spaces
provided below.
Use this table as a quick reference guide.
Each time you adjust the settings, make a note in the table.

3.5 Electrical connections
The electrical connections for the thermometer power supply and temperature
output are made via the 6-way socket on the rear of the thermometer.
See Fig. 7.
The cable connections are as follows:
Electrical connection to the thermometer must be made by either:
• 6-wayplug(LANDPartNº206.551)
• 6-wayplughousedinBackCap(LANDPartNº091.562)
• Pre-wiredcable,4mlong(LANDPartNº029.673)
Toconnectthecable;
1) RefertoFig.8.Aligntheredmarkernearthelugsofthepre-wiredplug
with the red marker above the keyway in the socket on the thermometer.
2) Pushtheplugintothesocket.
Todisconnectthecable;
1) Gripthelockingsleevesectionoftheplug.
2) Pulltheplugoutwardstoreleasethelockingmechanismanddisconnect
the cable.
