Short press
utton，the meter top right corner displays”--AU”to indicate
this function is started. Meanwhile, the laser output wavelength in the source module
will e switched automatically according to the change of the same wavelength in the
power meter module.
For example
For exampleFor example
For example：
：：
：
the meter internal source module has 1310/1490/1550 wavelength，the test
wavelength in the power meter module is 850/1300/1310/1490/1550/1625. If the test
wavelength in the power meter module is switched to 1550nm，the laser output wavelength
in the meter source module will e changed to 1550nm automatically；On the contrary,
when the test wavelength in the power meter module is different from the output wavelength
in the source module, the source module cannot follow automatically to change the
wavelength, and also no optical power output.

Frequency light detection
In the power meter mode, when the power meter detecting port receives the frequency
light input signal and it’s tested under the a solute optical power unit, the top right
corner of the screen will show HZ sign, indicating the current light signal frequency
is ***HZ.（image 5-14）
Image 5-14
Notes：When using the frequency detection function, A type optical power meter only
detects frequency with the power range more than -40dBm；C type power meter detects
frequency with the power range mare than -20dBm.

In the power meter mode,press“ ”and“ ”，
at the same time, “U-01”will
appear on the screen top right corner, indicating that the meter has come to power value
cali ration mode. Press “ ”and “ ”
to increase or decrease the a solute
optical power value. When the adjusted value is what you need, you can press “ ”
to save the current cali ration value. After “----”appears on the screen, it means
the cali ration is ok and then press “ ”to exit.(image 5-15)
Image 5-15
For example
For exampleFor example
For example：
：：
：
take the 1310 wavelenght cali ration for an example：
①
Select a high-sta ility 1310nm source, and then connect it to one end of patch
cord. The other end of the patch cord is inserted to the detecting port of the standard
power meter and tightens it. Choose 1310nm wavelength in the standard power meter,
and read the a solute optical power value, for example, we can set it for A.
②
Removed from the detecting port of the standard optical power meter, patch cord
is inserted to the detecting port of the cali rated instrument power meter. Then
11
change the wavelength in the cali rated optical power meter to 1310nm. Press
“ ”and “ ”
to increase or decrease the a solute optical power value
displayed on the cali rated instrument screen. When the a solute optical power value
on the cali rated instrument is A, press“
”
””
”
to save the current cali ration
value. “----” on the screen indicates that the cali ration is done.
③
Other wavelength cali ration is just like 1310nm wavelength， after cali ration,
press“ ” to exit.

Care and Maintenance
7.1 Keep the sensor port clean from fat, pollution; not use dirty and non-standard
fi er-optic adapter connector; not to e inserted to the adly-polished port. Otherwise
12
the sensor port can e damaged and the whole system performance will e affected.
7.2 Insist on the use of one fi er-optic adapter as possi le.
7.3 Once the instrument is not used, cover it with dust cap to keep the port clean
and to avoid measurement deviation due to the long exposure to the air.
7.4
Carefully insert or remove the optical adapter connector to avoid port
scratches.
7.5
Clean the optical adapter connector regularly and use the special cleaning
swa to wipe around it gently.
