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.
1550nm
Wavelength---wavelength of laser.
Manual
20Km
Scan mode---Manual and auto mode. Under auto mode, it will match the Distance,
range and pulse width .
1us
15s
Range---match with the length of measured optic fiber, usually over one level.
0.05dB
Pulse width---set the pulse width of output laser. Usually, small pulse width can measure
65.0dB
close event, large pulse width can measure remote distance,but enlarge event's blind area.
3.0dB
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.
1.46832
52.1
Reflection threshold---treat as an event when the reflection is higher than setting value.
Open
End threshold---treat as the end of optic fiber when the loss is higher than setting value.
Close
Reflective rate---represent the average refractive index of entire optic fiber.
Scatter coefficient--- the intrinsic value of Rayleigh Scattering.
Optical detector---set whether to check light input in the fiber before measurement or not.
Real time analyse---set whether to analyses events after real time measuring or not.
