Setting Thresholds and Correction Factors
You may apply a correction factor (CF) to measured power to compensate
for inaccuracies or drifts. You should change the CF after performing an
offset nulling.
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.
Note: Some other products express the CF in dB, so the CF would be added to
measured power.
IMPORTANT
If you revert to factory settings, you will erase all your thresholds
and correction factors. The pass/fail status feature will be disabled
automatically.
