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 absolute 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)

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.

at the same time, “U-01”will
appear on the screen top right corner, indicating that the meter has come to power value
calibration mode. Press “
”and “
”
to increase or decrease the absolute
optical power value. When the adjusted value is what you need, you can press “
”
to save the current calibration value. After “----”appears on the screen, it means
the calibration is ok and then press “

For example:
:
:
:take the 1310 wavelenght calibration for an example:
①
Select a high-stability 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 absolute 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 calibrated instrument power meter. Then
