Menu-Measure settings
Measure settings menu is used to set relative measurement data, which
the judgment of events list is based on. Wrong setting might leads to wrong or
missing events.
Wavelength---wavelength of laser.
Scan mode---manual and auto mode. Under auto mode, it will match the
distance, range and pulse width.
Range---match with the length of measured optic fiber, usually over one level.
Pulse width---set the pulse width of output laser. Usually, small pulse width can
measure close event, large pulse width can measure remote distance, but
enlarge event's blind area.
Average time--- can set between 5 second and 180 second as average
measurement time.
Splice loss---treat as an event when the loss is higher than setting value.
Reflection threshold---treat as an event when the reflection is higher than setting value.
End threshold---treat as the end of optic fiber when the loss is higher than setting value.
Refractive rate---represent the average refractive index of entire optic fiber.
Scatter coefficient--- the intrinsic value of Rayleigh Scattering.
