Setting a Power Correction Factor
Setting a Power Correction Factor
You may apply a correction factor (CF) to the measured power to
compensate for inaccuracies or drifts. You should change the CF after
performing an offset nulling.
The power value after correction will correspond to:
where:
Power
corrected
= the corrected power value
Power
measured
= the measured power value
CF = the correction factor
For each favorite wavelength, the CF is set to 1.00 at the factory, but
allowed values range between 0.85 and 1.15.
To set a correction factor for one or more wavelengths:
1. Press Menu, select Setup > Power Meter, and then press Enter.
OR
From the Power Meter pane, press Setup (F1/F2 key).
2. Using the up/down arrows, scroll through the
list to select the wavelength for which you
want to modify the correction factor.
3. Press Edit (F1/F2 key).
4. Set the new value and press OK (F1 key).
