Changing Correction Factor
Correction factors are used to adjust the Optical Power Meter (OPM) and
PON Power Meter (PPM) measurements. The Correction factor is specified
by wavelength only, and the fiber core size is not taken into account.
FastReporter allows you to change the correction factor for PPM file types.
These corrections should be made before the measurement is taken and
should be stored with each measurement. A correction factor of 1.0 has no
effect on the measurement.
Note: Correction factor is not available for measurements from iolm files.
To change Correction Factor:
1. Open a PPM or an OPM measurement file.
2. Select the measurements for which you want to change the correction
factor. You can select more than one using the Ctrl and Shift keys.
3. In the Results window, select the Summary tab.
4. Modify the correction factors associated with the wavelengths as
needed. Click the desired correction factor value under Test Settings
column and modify it.
