 Test Range：Setting scanning track range.
Range setting is based on the actual length of the optical fiber to select the corresponding predefined range,
must be greater than the length of the measured optical fiber, usually required to be set to about twice the
length of the measured optical fiber. The longer the distance, the longer the test time.
Setting method: Under the parameter setting interface, press the [Range], that is, 500m ~ 256km option,
press to select the corresponding range.
 Pulse Width：Setting the width of laser pulse emitted by the instrument.
Pulse width settings vary with distance settings. This series of OTDR has simplified the test pulse width
according to the range of different lengths, which greatly facilitates the operator's selection process. In
practice, it is recommended to use the upper limit pulse width of the optional range.
Narrow pulse：Adjacent time (reflection and loss) can be measured, but long distance cannot be measured.
Wide pulse: Long distance can be tested, but multiple adjacent events can be identified as a single event.
Setting method: Under the parameter setting interface, press the menu of Pulse, that is, the option of
3ns~20000ns appears, and press to select the corresponding pulse width.
 Average time: The range is between 5s and 300s.
Setting method: press [Test time], the 5s ~ 300s options appear, and select the corresponding time.
