Performing a SM RL1 Self-calibration•

Verify the detector diffuser glass is clean and free of defects
o If the diffuser is dirty, gently use a lint free wipe or swabo IPA and low pressure compressed air can be used on the diffuser plateo If it is scratched and cannot be cleaned, please contact support@jgroptics.com✓www.jgroptics.com© JGR Optics Inc.

Performing a SM RL1 Self-calibration•

Carefully reattach the output panel to the RL1
o Use your free hand to help guide the fiber back in, avoiding any twists or bends
o If you feel any resistance, stop, pull out slowly then try again

Performing a SM RL1 Self-calibration•Start the hardware validationo If the electronics fail, it’s possible the APD is not sufficiently warmed up. Leave the unit on then tryagain. Depending on the environment, this could take up to 30 min.

Common issues which can result in a failed step of the self-calibration:•Connector contaminationo microscopic airborne dust, chemical residuals or contact with surfaces are common sources ofconnector end-face contaminationo inspect and clean both ends before every mating
o if using a lint free wipe is not sufficient, try using IPA and remember to use a dry lint free wipe
after applying the IPA to remove any residue•Poor fiber managemento bends and twists of the output lead or test jumper can affect the stability of the unit
o use a heat-gun to relax the fiber’s plastic jacket and smooth out any kinks•Microcracks
o fiber mishandling can cause microcracks in fiber causing instability
o if there is no connector contamination and the fiber management is good but you still haveissues, try replacing the test jumpero poor handling of the output lead can cause microcracks – if this happens, the unit will need to be
