    To deactivate/reactivateauto-off: When unit is on, press Installing the EXFO Universal Interface (EUI) The EUI fixed baseplate is available for connectors with angled (APC) or non-angled (UPC) polishing. A green border around the baseplate indicates that it is for APC-type connectors.

  • Page 10: Cleaning And Connecting Optical Fibers

    To ensure maximum power and to avoid erroneous readings: Always clean fiber ends as explained below before inserting them into the port. EXFO is not responsible for damage or errors caused by bad fiber cleaning or handling. Ensure that your patchcord has appropriate connectors. Joining mismatched connectors will damage the ferrules.

    Measuring Power or Loss (FPM-300) 4 Measuring Power or Loss (FPM-300) Nulling Electrical Offsets Temperature and humidity variations affect the performance of electronic circuits and optical detectors. Nulling the electrical offsets eliminates these effects. Your unit has been designed not to require offset nulling under normal operation, but you should perform it whenever environmental conditions change significantly or when measuring very low power values.

  • Page 13: Referencing Your Power Meter To A Source

    Measuring Power or Loss (FPM-300) Referencing Your Power Meter to a Source In reference mode, your unit displays the loss created by the fiber under test only, since a reference value is subtracted from the measured power. Note: You must set a reference value separately for each wavelength.

  • Page 15: Measuring Power Or Loss

    Measuring Power or Loss (FPM-300) Measuring Power or Loss Measuring absolute power or link loss is done the same way, except for the referencing step. To perform power or lossmeasurements: If necessary, perform an offset nulling (see Nulling Electrical Offsets on page 2.
  • Page 16 When the unit detects a modulated signal, it beeps and displays the modulation value and average measured power or loss (see left illustration above). You may notice a slightly unstable last digit. If necessary, change the displayed units by pressing dBm/W 9. Repeat the procedure for other wavelengths. FPM-300/FLS-300...

    Auto is a modulated signal detected by compatible units (see Note: Automatically Detecting Wavelength on page 15). It provides longer battery life than CW, but covers a reduced power range. To change the signal modulation: Activate the source. Press to switch between available modulations. FPM-300/FLS-300...

  • Page 19: Sending Source Power Value With Signal

    Your source can transmit a user-defined power value to compatible power meters (such as FPM-300) through the fiber. If the reference source is far from the power meter, you can connect your source to the power meter to send the reference value.

    Maintenance 6 Maintenance This product contains no user-serviceable parts. However, it contains sensitive electronic and optical components, and should be handled carefully and stored in its carrying case when not in use. To help ensure long, trouble-free operation: Always inspect fiber-optic connectors before using them and clean them if necessary.

    Slowly insert the cleaning tip into the EUI adapter until it comes out on the other side (a slow clockwise rotating movement may help). 4. Gently turn the cleaning tip one full turn, then continue to turn as you withdraw it. FPM-300/FLS-300...
  • Page 23 Maintenance 5. Repeat steps 3 to 4 with a dry cleaning tip. Note: Make sure you don’t touch the soft end of the cleaning tip. 6. Clean the ferrule in the connector port as follows: 6a. Deposit one drop of isopropyl alcohol on a lint-free wiping cloth. MPORTANT Since isopropyl alcohol is not absolutely pure, it may leave residues if used abundantly or left to evaporate (about 10 seconds).

  • Page 24: Cleaning Fixed Connectors

    Since isopropyl alcohol is not absolutely pure, evaporation will leave microscopic residue. Make sure you dry the surfaces before evaporation occurs. With a dry lint-free wiping cloth, gently wipe the same surfaces three times with a rotating movement. Throw out the wiping cloths after one use. FPM-300/FLS-300...
  • Page 25 Maintenance 6. Moisten a cleaning tip (2.5 mm tip) with only one drop of isopropyl alcohol. MPORTANT Alcohol may leave traces if used abundantly. Avoid contact between the tip of the bottle and the cleaning tip, and do not use bottles that distribute too much alcohol at a time.

  • Page 27: Recalibrating The Unit

    Under normal use, we recommends calibrating your unit every three years. The FlexCare warranty program includes Calibration/Verification Note: packages (see Service and Repairs on page 30). To view the last calibration date (FPM-300 only):  at the Hold down and press (power meter) same time.
