Real-time and averagemeasurement
Real-time measurement canquickly judge basicfaults of optical fiber. Press
button to start real-timemeasuring. During measuring, you can change
range, zoom inor zoom out . Press button again or button to
stop. The devicewill not analysesevent after real-time measurement in default.
Unless you turn on RT analyse in System settings,the device willanalyse events
according to thelast refreshed waveform.
Average measurement canjudge the line condition more accurate. It can get a
better SNR andfits high requirement circuit. Press button to start. Usercan
set measurement timefrom 5 secondto 180 second. The device analyses events and
generates event listautomatically. Press button during measuring,device
will stop measuring,analyses events and generates event list automatically.

event list onthe bottom of waveform interface. Press
button to showthe whole event list. Six types of events as
followed:
Press Up orDown button to select an eventwhich needs tobe
located by cursoron the waveform. Then press button
to return to waveform interface. The cursorwill stay onthe
position of theselected event. Press button to return to

The device supports userto change measurement range during real-time
measurement. Start Real-time measuringfunction and press Up or Down button to
increase or decreasethe range. Andit also supports to change the cursorposition
and zoom in/outwaveform in realtime, which means youcan zoom inpartial
waveform while measuring to judge the network fault.
