After Auto mode started, according to the situation of optical fiber link which
connecting the equipment, application program will estimate the optimum setting
automatically and it will need around 5s. If the testing was cut off, any date won’t be
displayed.
Except the specific light port (light port used for online testing), do not connect the
optical fiber which load signal to the OTDR port, any external signal over -30dBm will
affect the OTDR sampling and cause permanent damage to the OTDR.
8.2 The procedures of auto testing mode
Test and get trace in Automode:
1.
Connect the optical fiber to the right OTDR light port.
2.
Set parameter: set the “Range” to “ AUTO”.
3.
Set testing time span.
4.
Start testing: Use stylus click [
] or press down the “
”
(Start/Stop) on front panel.
5.
After test, can save the trace, check the trace, re-analyze the trace and etc.
As to the detailed operation way, please refer to relative paragraph
previous.
u
When testing automatically, Range is “AUTO”
u
When setting the parameter, if the optical fiber parameter is not clear, can
directly use the default value, but it may cause a bigger testing error.
9 Test the optical fiber in Manual mode
Manual mode can set various test parameter more precisely.
The premise is know the general situation of optical fiber and then set parameters
precisely and gets more ideal test result.
