Introduction for optical power meter module
1. Switch the measuring wavelengths
You can choose one of six kinds of wavelengths:
850nm, 1300nm, 1310nm, 1490nm, 1550nm and 1625nm
through this key. The chosen wavelength will be displayed
in LCD screen. When the instrument is power-on, it defaults
the wavelength of 1310nm, and circulates in order of
1310nm, 1490nm, 1550nm, 1625nm, 850nm, 1300nm

how absolute power and relative power value.
The instrument defaults the absolute measurement of
optical power. The value displayed by main display 2 means
logarithmic power value (dBm). The value displayed by
main display 3 means linear power value (

, the instrument enters optical source output
state; shortly pressing

”
to quit laser source module,
return back to optical power test state.
If you set laser in working state, these two modules can
work at the same time.
