6.3.3 Completecalibration(withtemperaturecompensation)

Thiscalibrationmethodisusedtoadjustthelinearityofthepressuresensoratspecific

predefinedpressurelevelsandtemperatures.Duringthecalibrationsequencethe

pressuresensoriscalibratedatroomtemperatureandatatemperatureofapprox.55

°Cinsixstagesatnormalatmosphericpressureandat800,600,400,200and10

mbar.

NOTE

Thiscalibrationprocessmayonlybecarriedoutbyauthorizedservicetechnicians.

Duringthecalibrationsequence,thesystemcarriesoutaplausibilitycheckonthe

measuredreadingsandindicatesafaultiftheconfirmedreadingsareimplausible.

u Connectthereferencepressuregaugetothesamevacuumsystemthatthepump

andinterfaceunitareconnectedto.

u Onthecalibrationmenu,selecttheoptionCompletepressurecalibration.

Fig.19:Menu>Pressuresensorcalibration>Completepressurecalibration.

u Usingthearrowbuttons,adjustthespecifiedreferencepressuretothefigure

shownonthereferencepressuregaugeandpressOKtoconfirm.

u PresstheNextbutton.

u UsingtheP↑andP↓buttons,increase/decreasethevacuuminthesystemuntilthe

pressureshownonthereferencegaugeiswithin±10mbarofthespecifiedsetting.

u Repeatthelastthreestepsforeachofthepressurelevelslistedabove.

u Whenthesixpressurelevelshavebeencalibratedatroomtemperature,placethe

interfaceunitinalaboratorykilnandheatitupto55°C(approx.1.5hours).

u CAUTION!Riskofskinburns.Wearprotectivegloves.Leavetheinterfaceunit

inthekilnandrepeatthestepssetoutabove.

u Oncompletionofthelaststep,pressOKtoconfirmthecalibration.

Thecalibrationsettingsaresavedandthedisplayrevertstothedefaultscreen.
