6.3.2 Simplecalibration(withouttemperaturecompensation)

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

predefinedpressurelevels.Duringthecalibrationsequencethepressuresensoris

calibratedatroomtemperature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Simple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 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.
