1 Introduction
1.1 About this guide
This guide gives the information necessary for you to operate a LAND UNO
Fibroptic Thermometer. Basic information regarding installation is contained
within the Installation Guide.
1.2 About the UNO Fibroptic thermometer
The LAND UNO thermometer is an accurate, non contact thermometer
designed for independent or STAND ALONE use.
The thermometer features include:
• Stand Alone operation.
• Built in Averager or Peak Picker for signal conditioning.
• Built in Emissivity or Non Greyness controls.
• Achoiceofbreopticslightguides,enablingthethermometer's
electronics to be located away from the often hostile measurement
location.
• A choice of optic head focus distance.
• Electrical connections for a 4 to 20mA output, linear over the
temperature span of the thermometer, and an emissivity input for high
accuracy temperature measurement.
The LAND UNO range of thermometers and rugged mounting accessories is
designed to provide precise, non contact temperature measurement solutions.
Internal controls for emissivity or non greyness together with selectable
timefunctionsallowthethermometertobeconguredtosuitawiderange
of industrial applications. A comprehensive range of mountings is common
to other LAND products, maximising commonality and simplifying system
upgrades.
1.3 Unpacking the thermometer
The package containing the thermometer will contain the following items:
• CD containing this UNO User Documentation.
• UNOFibropticthermometer,optichead(ttedwithprotectioncap)and
lightguide.
• 2.5mm Hex screwdriver.

3.1 Positioning the Optic Head
IfyourUNOFibropticthermometeristtedwithaLaserAlignmentUnit
(e.g. U1 600/1600 C Y L), the laser be used to aid the installation of the
thermometeropticheadbydeningthetargetareaonwhichtheoptichead
is aligned. This is particularly useful in applications where the target size is
small and/or where correct alignment is critical. For more information on the
Laser Alignment Unit, refer to Section 5.
In many cases, there are few options on location of the optic head, as this is
generally dictated by the particular measurement application. Observe the
following precautions:
1) Ifyourthermometerisan'U'seriesthermometer(e.g.U1600/1600C
L), it must be positioned such that, at the chosen target distance, the
targetislargeenoughtocompletelylltheoptichead'seldofview.
Refertothetargetsizetables,Section5.Thethermometer'sviewofthe
target area must not be obstructed.
2) Ensurethattheanglebetweentheoptichead'slineofsightandthe
target area is as near to 90° as possible. However, if this is not possible,
a viewing angle of up to 45° is acceptable.
3) If the optic head is located in an atmosphere containing a high
proportion of dust/smoke etc, an air purge must be used in conjunction
with the optic head. This prevents the lens from becoming dirty. Refer
to the Installation Guide supplied with the mounting/purge assembly.
3.1.1 Installing the optic head
The optic head can either be mounted directly into a threaded hole in a user-
supplied mounting plate, or connected to one of the range of Land Fibroptic
thermometermountingsbymeansofthe'QuickReleaseFitting',LandPartNº
029.591.
To mount the optic head in a plate:
1) Refer to Fig. 4(a). Unscrew the clamp nut nearest the lens on the optic
head.
2) Screw the optic head into an M22 x 1.5P threaded hole in the plate.
3) Re-attach the clamp nut onto the optic head. Tighten the nut so that the
mounting plate is held securely between the two clamp nuts on the optic
head.
To mount the optic head into Land Fibroptic thermometer mountings:
1) Refer to Fig. 4(b). Screw the two clamp nuts up as far as they will go on
the thread on the optic head.
2) Screwtheopticheadintothe‘QuickReleaseFitting’.
3) Attachthetting,plustheoptichead,totheLandFibropticthermometer
mountingbymeansofthetwistlockontheQuickReleaseFitting.

Fibroptic Thermometer User Guide
3.2 Installing the lightguide
Wheninstallingthebreopticlightguide,observethefollowingprecautions;
1) Ensure that the lightguide is not be subjected to any tension or other
undue force. It is not necessary to clamp or lash the lightguide to
surrounding structures unless, by leaving it hanging, it will vibrate
violently, be a nuisance or a hazard.
2) Treat the lightguide as if it were a lightweight electrical cable and protect
it if necessary. The minimum bend radius is 50mm.
3.3 Positioning the Thermometer
When choosing a location for the thermometer, observe the following
precautions:
1) If the thermometer is to be installed in a location where the ambient
temperatureisoutsidetherangespeciedforthethermometer,itmust
be mounted in a special cooling/heating jacket available from Land
Instruments International.
2) If the thermometer is to be used in conjunction with a protection jacket,
refer to the installation guide provided with the jacket.
3) If the thermometer is to be installed in a location where the ambient
temperatureiswithintherangespeciedforthethermometer,itcanbe
mounted using the two tapped holes on the mounting pad. Either hole
can be used for direct tripod mounting.
4) Choose a location for the thermometer which is free from excess
vibration, dirt and moisture.
5) It is important that, in order to prevent any possibility of water ingress
into the electronics/detector module, the thermometer is mounted in the
orientation shown in Fig. 3.
6) It is recommended that, in order to minimise the build-up of dirt etc. on
the electrical and lightguide connectors, the thermometer is mounted
such that these connectors are on the underside (as shown in Fig. 3).

4 Using the Thermometer
Beforenalinstallationofthethermometer,theinternalcontrols(i.e.
Emissivity, Averager response speed or Peak picker decay rate) must be set
to match the particular measurement location. This involves removing the
internal chassis from the thermometer cover.
4.1 Removing the chassis from the thermometer cover
Caution
Ensure that the thermometer is disconnected from the power
supply before removing the chassis from the cover.
Ensure that the thermometer is dismantled in a clean laboratory
orofceenvironment.
1) Refer to Fig. 5. Use the 2.5mm Hex screw driver to loosen the four
captive screws (A).
2) Slide the chassis out of the thermometer cover.

4.3.1 U series thermometers
In U series (i.e. single wavelength) thermometers, the emissivity value is set
using switches SW2 and SW3. Refer to Fig. 7.
The emissivity can be set in the range 0.10 to 1.09 in steps of 0.01.

4.3.2 V series thermometers
In V series (i.e. ratio) thermometers, the non greyness value is set using
switches SW1, SW2 and SW3. Refer to Fig. 8.
The non greyness can be set in the range 0.800 to1.199 in steps of 0.001.
ThesettingofswitchSW1denotestherstgureafterthedecimalpoint
of the non greyness value. However, if SW1 is set to either ‘0’ or ‘1’, this
denotes a ‘1’ before, and either a ‘0’ or ‘1’ (respectively) after the decimal
point of the non greyness value.
e.g. For a non greyness value of ‘0.995’, set SW1 to ‘9’, SW2 to ‘9’ and SW3
to’5’. For a non greyness value of ‘1.199’, set SW1 to ‘1’, SW2 to ‘9’ and SW3
to ‘9’.

4.4.2 Peak picker
The Peak picker time function is selected by setting switch, SW5, to position
2 (i.e. down). The Peak picker decay rate can be set, via switch SW4, to any
one of the ten values shown in Fig. 9.
The CMD (Command) input, available between pins 3 and 7 of the thermometer
electrical connector, enables remote resetting of the Peak picker time function.
(Refer to Section 4.8.1). When the CMD input is open circuit, the Peak picker
operates under the control of switches SW4 and SW5. When the CMD input is
short circuit, the Peak picker function is RESET and the output signal reverts to
tracking the input, regardless of the setting switches SW4 and SW5.
A graphical explanation of the Peak picker time function is given in Fig. 11.
