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.
6 of 15
IPU 40151 Issue 2
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.
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.

4. Insert the USB connector of the SD card reader into a USB port on the PC,
using the extender USB cable if required.
5. Follow the card reader’s installation instructions if prompted by Windows.
6. Either open “My Computer” and copy the .snp files from the SD card to the
PC (recommended), or leave the SD card in place whilst the “IRISYS 1000
Series Imager” PC software is running and open the files directly from the
SD card.
NOTE: Image files must retain their file name (IRI1020_XXXX.snp). If they are
renamed on the PC they will no longer be readable by the imager.
Warning:
If the Imager SD memory card is removed from the imager and reformatted using a
PC, the SD memory card will take on the format of that device. When the SD memory card is then
returned to the imager the SD memory card will not be readable by the imager and the message “No
MMC/SD card” will appear. The SD memory card MUST be reformatted with its original file format
(either FAT or FAT16)

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 emissivity’s 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.
Below is a list of approximate emissivity values for a range of materials for
making more accurate temperature measurements.
NOTE: Emissivity values often vary with temperature and wavelength so this
table is included as a guide only.
