1.0 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. More detailed information regarding servicing, repair and calibration of the
thermometer is contained in the Service Manual.
1.2 About the UNO Fibroptic thermometer
The LAND UNO thermometer is a highly accurate, non contact thermometer designed
for independent or STAND ALONE use.
The thermometer features include:
lStand Alone operation.
lBuilt in Averager or Peak Picker for signal conditioning.
lBuilt in Emissivity or Non Greyness controls.
lA choice of fibre optics lightguides, enabling the thermometer's electronics to
be located away from the often hostile measurement location.
lA choice of optic head focus distance.
lElectrical connections for a 4 to 20mA output, linear over the temperature
spanof the thermometer, and anemissivity inputfor high accuracytemperature
measurement.

TheLAND UNO range of highaccuracy thermometers and rugged mountingaccessories
is designed to provide precise, non contact temperature measurement solutions.
Internal controls for emissivity or non-greyness together with selectable time functions
allow the thermometer to be configured to suit a wide range of industrial applications.
A comprehensive range of mountings is common to other LAND products maximising
commonality and simplifying sytem upgrades.
1.3 Unpacking the thermometer
The package containing the thermometer will contain the following items:
lEnvelope containing this User Guide.
lUNO Fibroptic thermometer, optic head (fitted with protection cap) and
lightguide.
lDocumentation binder with dividers.
l2.5mm Hex screwdriver.
l2.5mm flat bladed screwdriver.
1.4 Nomenclature
The thermometer detail label is on the rear face of the thermometer above the electrical
connector. The thermometer instrument type nomenclature is explained in Fig. 2.
Make a note of your thermometer's instrument type and Serial Number in the space
provided below.
Instrument type:
Serial Number:
The optic head variant (A10, A25 or A50) is determined by the type of spacer fitted.
A10 = Red spacer (15mm long) = 10cm focus distance
A25 = Blue spacer (3mm long) = 25cm focus distance
A50 = No spacer fitted = 50cm focus distance

2.1 Positioning the Optic Head
If your UNO Fibroptic thermometer is fitted with a Laser Alignment Unit (e.g. U1
600/1600 C YL), the laser be used to aid the installation of the themometer optic
head by defining the target area on which the optic head 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 4.0.
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;
(i) If your thermometer is an 'U' series thermometer (e.g. U1 600/1600 C
L), it must be positioned such that, at the chosen target distance, the
target is large enough to completely fill the optic head's field of view.
Refer to the target size tables, Section 4.0. The thermometer's view
of the target area must not be obstructed.
(ii) Ensure that the angle between the optic head's line of sight and the
target area is as near to 90° as possible. However, if this is not possible,
a viewing angle of up to 45° is acceptable.
(iii) 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.
2.1.1 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
thermometer mountings by means of the 'Quick Release Fitting', Land Part Nº
029.591.
To mount the optic head in a plate
(i) Refer to Fig. 4(a). Unscrew the clamp nut nearest the lens on the optic
head.
(ii) Screw the optic head into an M22 x 1.5P threaded hole in the plate.
(iii) 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
(i) Refer to Fig. 4(b). Screw the two clamp nuts up as far as they will go
on the thread on the optic head.
(ii) Screw the optic head into the 'Quick Release Fitting'.
(iii) Attach the fitting, plus the optic head, to the Land Fibroptic thermometer
mounting by means of the twist lock on the Quick Release Fitting.

2.2 Installing the lightguide
When installing the fibre optics lightguide, observe the following precautions;
(i) 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.
(ii) Treat the lightguide as if it were a lightweight electrical cable and protect it if
necessary. The minimum bend radius is 50mm.
2.3 Positioning the Thermometer
When choosing a location for the thermometer, observe the following precautions;
(i) If the thermometer is to be installed in a location where the ambient
temperature is outside the range specified for the thermometer, it must be
mounted in a special cooling/heating jacket available from Land Infrared.
(ii) If the thermometer is to be used in conjunction with a protection jacket, refer
to the installation guide provided with the jacket.

(iii) If the thermometer is to be installed in a location where the ambient
temperature is within the range specified for the thermometer, it can be
mounted using the two tapped holes on the mounting pad. Either hole can
be used for direct tripod mounting.
(iv) Choose a location for the thermometer which is free from excess
vibration, dirt and moisture.
(v) 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.
(vi) 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).

3.3 Setting the Emissivity/Non Greyness value
3.3.1 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 to1.09 in steps of 0.01.
When switch SW2 is set from 1 to 9, this denotes the first figure after the decimal point
of the emissivity value. e.g. for an emissivity value of '0.83', set SW2 to '8' and SW3 to'3'.
When switch SW2 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 SW2 to '0' and SW3 to'0'.

3.3.2 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.
The setting of switch SW1 denotes the first figure after the decimal point 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'.
