Additional troubleshooting for MIC thermal imagers.
Problem Explanation Solution
A small square appears
intermittently at the
upper right of the video
output.
This is the Flat Field Imminent
Symbol. It warns that flat-field
correction (FFC) is about to
begin.
Do nothing; this is normal
operation for the thermal
camera.
The thermal image
appears ’grainy’.
This often occurs when the
temperature of the camera
fluctuates, such as after the
camera is powered on, or when
ambient temperature is
changing.
Wait for the camera to
perform a flat-field correction
(FFC).
The picture is dark. Increase the Gain Level in the
Camera > Picture Settings
Thermal menu.
The contrast is too low. Increase the Gain Bias in the
Camera > Picture Settings
Thermal menu.
The picture is too noisy. If the camera is set to Manual
contrast mode (in the
Camera > Picture Settings
Thermal menu), then reduce
the manual contrast or
switch to AGC mode.
Reduce the Gain Level in the
Camera > Picture Settings
Thermal menu.
Details in the scene are
washed out.
Change from Manual contrast
mode to AGC mode in the
Camera > Picture Settings
Thermal menu.
The picture is not in
focus.
Check that the objects that
are not in sharp focus are
within the allowed distance
range for your model of
thermal camera.
The picture shows
images that aren’t
present in the scene.
Check to see if the heat of
objects is being reflected off
a surface, causing thermal
reflections.
