In this interface, if the laser source (ShinewayTech laser source with AutoID function) on
the other side of the tested fiber enables AutoID, then the optical power meter will
automatically identify the incoming signal wavelength and set the reference value sent from
the laser source as reference (“AutoID” will appear in this interface) to enhance the testing
efficiency and avoid potential operation fault. If the laser source does not enable AutoID
function, user can press
button to set currently measured power value as reference
value or manually adjust the reference value.
If you need manually adjust reference value, press
button to enter reference setting
interface, see Figure 3.8.
