Comments
Move the joystick left/right to enable or disable
noise reduction.
When Noise reduction is set to On, the image
noise decreases and the image appears more
stable.
However, when the camera or the object moves,
and Noise reduction set to On, this may create
some image smearing.
Press the Adjust region button to display a region
on the screen that will be used when autoadjusting
the camera.
Press the joystick left/right to change the shutter
period, or switch off the shutter.
➲ Please note the following:
Although the shutter period works independent-
■
ly of other functions described in this publica-
tion, FLIR Systems recommends that Short is
selected when using the camera for detection
of face temperature.
Selecting Normal will calibrate the camera at
■
least every 15th minute, while selecting Short
will calibrate the camera at least every 3rd
minute.
If the shutter is switched off, a symbol (*) will
■
prefix the result at the time a shutter sequence
should have taken place, thus indicating uncer-
tainty in the measurement result.
