MSA ULTIMA X5000 - How to Calibrate Xcell Sensors

Failuretofollowthiswarningcanresultinseriouspersonalinjuryordeath.
Ifthereisnotargetgasintheatmospherearoundthesensor,usingazerogascylinderisoptional.
ToZerocalibratethesensor,
1. AttachtheSensorGuardtothebottomofthesensor.
2. PlacethegreenCalibrationCapovertheSensorGuardinletsothatitisflushwiththebottomoftheSensorGuardand
completelycoverstheSensorGuardinlet.
3. AttachthetubingtotheplasticstemprotrudingthroughthegreenCalibrationCap.
4. Screwtheregulatorontothetopofthezerogascylinder.
Ifapasswordisenabled,youwillneedtoenterithere.
NOTICE
Ifthecalibrationcapcannotbeused(suchasforaremotesensorapplication),ambientwindconditionsmustbeminimized
duringcalibrationtoavoidacalibrationwithincreasedsensitivity.
5. ScrollandselectCalibration.
6. ScrollandselectZero Calibration.
7. OncethescreendisplaysZeroSoaking,turnonzerogasflowbyturningknobontheregulator.
8. WaitwhilethedevicedisplaysthecountdownoftheZeroCalibration.
9. Oncethezerocalibrationiscomplete,aZeroPASSorFAILisdisplayed.
If PASS displays, the procedure is complete. User may record the as found and as left values as an indication of the amount
of sensor correction performed during the calibration.
If FAIL displays, the procedure was unsuccessful.
10.Removethezerocalibrationequipmentfromthedevice,includingtheSensorGuardandCalibrationCap.
SensorswithTruCalandhaveDiffusionSupervisionenabledcangointoDiffusionSupervisionFaultifthegreen
calibrationcapisleftonaftercompletingazerocalibration.
WARNING!
Thegreencalibrationcapmustberemovedfromthesensorafterazerocalibration.Failuretodosocouldrestrictgasflow
tothesensorandresultinerroneouslylowreadings.
Failuretofollowthiswarningcanresultinseriouspersonalinjuryordeath.
