turning the original view upside-down. Pressing the
button a third time
rotates the field of view yet another 90°. Pressing the button a fourth time
restores the original view and extinguishes the red button backlight.
To remove glare, reflections or spots from the field of view, use the
button.
Pressing the button adds a red backlight to it, just like the other two buttons on
the probe controller.
This anti-reflection feature of the P18HPART is most useful for eliminating
reflections of the three forward-facing LEDs in the camera head from shiny
surfaces. Note that pushing the
button extinguishes the three forward-facing
LEDs and shifts responsibility for camera lighting to the two side-facing LEDs.
The net effect, as shown in the two photos below, is a clearer and more-
readable image.

You can also use the anti-reflection function to remove glare created by the
P18HPART’s mirrored viewing tip (see the next section of this manual for
installation and alignment instructions). The pair of images below illustrates the
net positive effect.
