DISPLAY PREFERENCES
MODE:
Sets the orientation of the LCD display. Three modes are available:
FLIP
LCD automatically alternates between portrait and
landscape modes based upon the physical
orientation of the OTDR
PORTRAIT
display is always in portrait mode
LANDSCAPE
display is always in landscape mode
DIMNESS:
Sets the level of the LCD backlight during power saving mode. Range of
values are 25 (dimmest) to 125 (brightest).
NOTE: higher values require more battery power
BRIGHTNESS:
Sets the level of the LCD backlight during normal operation. Range of
values are 150 (dimmest) to 255 (brightest).
NOTE: higher values require more battery power
SPEAKER:
Toggles the internal speaker either ON or OFF.
TRACE CLIPPING:
Toggles trace clipping mode either ON or OFF.
On a normal OTDR trace, as the sloping line of the trace approaches the noise floor of the
OTDR, the trace starts becoming less smooth, making events harder to see near the end of the
trace.
Trace clipping is a method that “clips” the top of the most reflective peaks, in order to draw the
sloping line away from the noise floor. This effectively smooths out the trace, allowing smaller
events to be more easily detectable.
While trace clipping is ON, reflectance measurements of clipped events are not affected.
