5.4 Lock/Unlock Palette Auto-Scale Mode
Note: For best results, allow a warm-up period of 3-5 minutes before using this feature.
The Lock/Unlock Palette Auto-Scale option allows the color palette range to be adjusted to
suit a given application. For example, when viewing both cold and hot objects in the same
frame, the palette auto-scaling will cause the palette to be ‘stretched’ to fit the whole range
of temperatures. However, this can cause smaller temperature variations to disappear, as the
difference between two colors might increase from 1° to 10°. In this case, the user may
choose to lock the scale with only the cold or medium-temperature object in the frame. This
would cause the hot object to saturate but will provide more detail to the colder objects of
interest.
If the user wishes to narrow the range of color and limit it to colors near the cold temperature
image, Lock/Unlock can be set to ‘Lock’ with no hot objects in the frame. To lock the scale,
press the Select button to access the Main Menu, scroll to the Lock icon, and press Select
again to toggle unlock/lock. Some experimentation and fine-tuning may be required to get the
best possible contrast for the application.
5.5 Screen Capture and Hold
Pressing the Image Capture button
captures the current MR160 screen. The screen will
hold (freeze) for seven (7) seconds, until an image filename appears indicating that the image
has been saved. During the seven second ‘hold’ period, the user can simply examine the image
and press the Back button to discard or press Select/Capture to save the image.
Images are saved in bitmap (.bmp) format. Images can be accessed on the MR160 screen using
the Image Review icon
available in the Main Menu. Then scroll the images using the Left and
Right navigation buttons.
