Auto
The Auto button can be set in the ‘Tools’ section to operate in two different modes:
•
“Ticked box” Continuous Auto - Continuously adjusts the temperature range
and sensitivity of the image for ease of viewing. In this mode the ‘Auto’
button can be used to switch Continuous Auto on or off.
•
“Unticked box” Continuous Auto - The ‘Auto’ button is used in a one shot
mode i.e. each time the button is pushed it will automatically adjust the
temperature range and sensitivity for the present scene.
With Continuous Auto off, the image can be adjusted in a manual mode using the Nav/Action
button, see Section
2.4.2.2
for more information.
Tools
Gives access to the following settings:
•
Image Label
– The user can enter their own selected name for saved
snapshots.
•
Ambient (
o
C) – The user can set the ambient temperature; if the emissivity (see
below) is not given the value of 1 the software compensates for the ambient
temperature to give more accurate temperature readings. Limited to 200ºC if value
entered is above 200ºC.
•
Calibration – If there is more than one calibration file available for the imager, the
user can select the appropriate file from this box. If there is only one calibration file
this selection box may not be displayed.
•
Emissivity – The user can select the emissivity for the material being imaged.
Setting the correct emissivity value is important to achieve the accuracy of
temperature readings, see note 3 in Section
3.1
.
•
Colour Map – The user can select one of three possible colour options:
o
Greyscale
o
Red-Blue
o
Green-Blue
•
Integration – The number of image frames to be integrated can be set to
‘Integration OFF’ or up to 10 frames. Note that this function reduces “noise” on the
image; it should be turned off when imaging a moving scene.
•
Temp. Units – The user can select the temperature units to be:
o
Celsius (
o
C)
o
Fahrenheit (

F)
o
Kelvin (K)
•

pixels.
•
2

Element – The user can select whether to have the second (SP2) temperature
cursor displayed on the screen.

Navigation/Action Button Operations
All Palms have a central Navigation/Action button. This is the only physical button used for
operating the IRISYS 1011 Imager software. The remaining buttons on the Palm are used for
other applications outside of the IRISYS software. The function of these buttons is dependant on
the brand of Palm; refer to your Palm Handbook for more information.
The Navigation/Action button can be depressed at five points and has five primary functions -
up
,
down
,
left
,
right
and
select.
