Why is the optical power unstable on my EXFO FPM-300 Measuring Instruments?
The optical power instability can be fixed by increasing the source power when in Auto mode, or switching the source to Continuous Wave (CW) mode.
What to do if my EXFO Measuring Instruments beeps a lot and the optical power is unstable?
The multiple beeps, unstable optical power, and blinking Auto (or modulation) indicator suggest that the power is too low to recognize Auto mode (or modulation). You should increase the source power or switch the source to CW.
Why can't I change the power meter wavelength on my EXFO Measuring Instruments?
You might be unable to change the power meter wavelength because the unit is receiving an Auto (or REF) signal from the source, or there is only one wavelength in the list. To solve this, change the source mode, and then retry. You can also add wavelengths.
What to do if light is detected while nulling offsets on EXFO Test Equipment?
If the EXFO Test Equipment detects light while nulling offsets, and nulling is not performed, ensure that the protective cap is correctly placed on the detector port, and then retry the nulling process.
Why EXFO Test Equipment has many beeps, unstable optical power and blinking Auto indicator?
If you observe many beeps, unstable optical power, and a blinking Auto (or modulation) indicator on your EXFO Test Equipment, it's likely that the power is too low for the device to recognize Auto mode (or modulation). To resolve this, increase the source power or switch the source to CW (continuous wave).
What to do if reference power is different than source output power on EXFO Test Equipment?
If the reference power is different from the source output power on your EXFO Test Equipment, the received power might be outside the detector’s range. Try changing the source output power to resolve this.
What to do if unable to change power meter dB unit on EXFO Test Equipment?
If you are unable to change the power meter dB unit or reference power on your EXFO Test Equipment, or if changed values are replaced, the unit might be receiving a REF signal from the source. Wait a few seconds until the power value is received, and then retry.
How to fix unavailable wavelength from source on EXFO Test Equipment?
If the wavelength sent from a compatible source emitting in Auto mode is not available on your power meter, change the source wavelength or switch the source to CW (Continuous Wave).
What to do if my EXFO FPM-300 Measuring Instruments shows 'LIGH'?
The 'LIGH' message indicates that light was detected while nulling offsets, which prevents nulling from being performed. To resolve this, correctly place the protective cap on the detector port, and then retry the nulling process.
How to fix reference power that is different from source output power on EXFO FPM-300?
If the reference power differs from the source output power, it means that the received power is outside the detector’s range. To fix this, you should change the source output power.
