Setting the Measurement Mode
Two measurement modes are available: real-time and average.
In real-time mode, the OTDR tests the connection status of the external optical fiber
in real time and update the test trace in time. In real-time mode, the measurement stops
only when you press [Run/Stop]; otherwise, the measurement goes on an on. In average mode,
the OTDR accumulates and averages the measurement data based on the selected measurement
duration. When the measurement time is equal to or longer than the measurement duration
set by the user, the current measurement stops and the measurement result is displayed.
Generally, you can select the average mode for measurement.
