4.0 Maintenance
4.1 InspectionandCleaning
Oncethedetectorhasbeeninstalledandpoweredup,itshouldprovidemaintenancefreeperformance
foryears.Thefollowingisasimpleguidelineforkeepingthedetectorfunctioningproperlyandtrouble
free:
4.1.1 TheD390detectorrequirednofieldcalibrationoradjustment.
4.1.2 ThedetectorisencasedinasealedPolypropyleneenclosurerequiringverylittlemaintenance.
However; in harsh chemical‐laden environment, dusty and oily places contaminant tend to
accumulateonthefrontviewingwindowthusreducingthedetectorsensitivity.Itistherefore
recommendedtocheckthedetectorandcleanthefrontsurfaceasneededwithsoftcottoncloth
andIPA(IsopropylAlcohol).Priortocleaningthefrontviewingwindow,itisrecommendedto
disconnectpowertodetector.
4.1.3 ThedetectorisfittedwithaTefloncablecompressionfittingandtightenedtopropertorquefor
