2.0 Operating the IRI 1020
Practical use of the IRI 1020 is detailed in this section.
2.1 Hardware
The IRI 1020 is designed for use as a handheld thermal imager. Thermal images stored on the supplied
memory card, can be transferred to a PC or laptop computer using the memory card reader. PC
software is for viewing and analysis of saved thermal images. Figure 5 shows the imager’s main
features, including the laser pointer button and aperture, imager lens, battery compartment, power
button and the door to the SD card slot.
Figure 5. The IRI 1020 Hardware.

2.3 Screen Display Items.
Figure 7. Screen Display Items.
CAUTION: The calibrated temperature output is the figure adjacent to the cursor identifier; the
temperature scale and display colours are for indication only.
2.4 Operating Notes.
Radiometry
All objects give off an IR signal which depends on the temperature of the object. For objects which are
not reflective (or shiny), the amount of IR can be used to estimate the object temperature - even at a
distance. The temperatures of the objects whose images fill the small green cursors are shown in the
chosen temperature units at the top of the screen. CAUTION The temperature of objects smaller
than these boxes may be hotter than the reported value.
Emissivity and Reflected Background
Emissivity has a maximum of 1 and minimum of 0 and is the opposite of reflectivity, an emissivity of 1
means that the object is not at all shiny and an emissivity of close to 0 means that it is very shiny
indeed. The IRI1020 can compensate for the emissivity of a viewed object if the emissivity is entered
into the camera. If the emissivity is less than 1, the object is partly shiny and therefore some of the IR
picture will have come from the surrounding background. The average background temperature must
therefore also be entered into the camera. Measurement accuracy falls at low emissivities and so the
value entered into the camera is limited to be no less than 0.2. CAUTION Objects with low
emissivity may be considerably hotter than the reading given by the IRI1020. The power-on value
of emissivity is 1.0 and the background temperature is not then taken into account. The current
emissivity and background temperature values are displayed at the top of the screen in the single cursor
mode.
Integration
The output of the radiometer is subject to noise in the electronics and in the infrared detector. The
noise can be reduced by increasing the integration setting. This averages several pictures together to
reduce the noise but at the expense of slower response when the camera or the viewed object is moved.

Level and Span
In order to get a visible picture, the IRI1020 focuses on a certain temperature range. This is
automatically determined and the temperature range is shown on the right hand side of the screen. The
LEVEL is the value at the centre of the scale and the SPAN is the difference between the top value and
the bottom value. Only objects in the centre third of the picture are taken into account by the IRI1020
in arriving at the automatic level and span.
If the manual mode is entered, the level and span will be locked at their current values but can be
adjusted by the arrow keys. This can be useful if comparative pictures of two different objects are
required or if small variations in a hot or cold object are to be measured.
Entering automatic mode at any time will restore a usable picture. Powering the unit off and on again
will restore all factory settings.
Over and under range values are indicated by red or blue coloured numbers, these readings exceed the
range of the instrument and should not be relied upon.
2.5 Buttons
Operation of the IRISYS 1020 imager is by means of the 4 hotkey buttons, hotkey 1 to hotkey 4, the 4
directional arrow buttons, the centre button and the laser button. The hotkey buttons are mainly used to
give control of the following functions. (See figures 9, 10 and 11 for the button locations.)
The centre button turns the imager freeze function on and off except when hotkey 2 cursor is selected.

8.0 Operating Notes and Precautions; Temperature Measurement.
The following should be noted when using the instrument as a temperature indicator:
1. The indicated temperature value is derived from a calibration obtained when the
instrument is in a thermally stable environment. If the instrument is not thermally
stabilised, there may be an error in the indicated temperature. Thermal stabilisation may
take a few minutes – a period of 5 minutes or longer may be necessary.
2. The calibrated temperature output is the figure in the temperature box; the temperature
scale and display colours are for indication only.
3. Caution should be observed in using the emissivity control – the user should explore the
effect on the observed temperature of an object when different emissivities are selected.
Figures associated with particular materials are supplied as a guide only.
Low values of emissivity should be used only with extreme caution as large errors in
temperature readings may be obtained with only small errors in emissivity.
4. Only the central 12 x 12 elements should be used for temperature measurements. The
camera should be positioned so that the item of interest appears within this area of the
display.
Caution: Do not adjust the lens focus. The lens is fixed focus and factory set.
9.0 Lens, Tables and Customer Feedback.
9.1 The lens and associated holder is not user adjustable. The focal point of the imager has been set at
manufacture according to specification. IRISYS will not be held responsible for any internal damage
should this mount be altered. Behind the lens is the accurately positioned chopper blade.
9.2 Emissivity Lookup Table.
