OSSIBLE
C: Optical output connectors dirty.
S: Disable optical output and clean optical connectors.
C: Use of incorrect optical adapters or connectors.
S: Use only the indicated optical adapters and connectors. If
measurement instruments accept different connector type, then
use hybrid patchcords. For shorter wavelengths (<1300nm), use
of special coupling patchcords with matching wavelength will be
necessary to couple the light efficiently.
C: Optical output connector damaged.
S: Measure optical output power with power meter and compare
with readout on Main Display. Return to Optilab for repair if the
difference is high (>4 dB) and cannot be corrected by cleaning or
replacing the optical connectors. Always apply dust cover plugs
to unused optical receptacles to prevent the damage of internal
optical connectors.
C: Static electrical discharge.
S: Wait 10 to 30 seconds for the display to refresh.
C: Insufficient ventilation.
S: Place unit in well ventilated area or supply additional fans for
ventilation.
C: Insufficient optical output isolation.
S: Connect isolator of corresponding wavelength to optical output
connector. The use of angled patchcords (APC) will help minimize
the light being reflected back into the laser and improve stability.
C: Blown fuse.
S: Contact Optilab, LLC for fuse replacement procedure.
C: Insufficient electrical voltage.
S: Check that the electrical supply is at least 110 VAC.
C: Power cord is loose.
S: Plug the power cord firmly into the unit.
C: Insufficient electrical voltage.
S: Check that the electrical supply is at least 110 VAC.
