Manual-no.: 999162 // 19/01/2011The pressure transducer VSP 3000 was adjusted using factory standards, which aretraceable through regular calibration in an accredited laboratory (German Calibrationservice) to the German national pressure standard. Depending on the process and/or on accuracy requirements, check the adjustment and readjust if necessary. Forreadjustment, the device has to be adjusted both at atmospheric pressure as well asunder vacuum.➨ For readjustment, install the pressure transducer in the same orientation in whichit will be operated later on at the application.➨ Allow the pressure transducer a period of minimum 20 minutes to preheat.If no adjustment is possible in the current pressure range, ”---- mbar” is displayed.Adjustment at atmospheric pressureAn adjustment at atmospheric pressure is only possible in theupper pressure range.Ventilate the pressure transducer VSP 3000 and/or the vac-uum system. Make sure that the vacuum connection at theVSP 3000 is at atmospheric pressure. Allow the pressuretransducer a period of minimum 20 minutes to preheat at thispressure.➨ In function ”Configuration” select the menu item ”Adjust-ment”.☞ The reading is automatically adjusted to ”1000 mbar”. Thisvalue is fix and can not be changed.➨ Press the selection knob to confirm.Adjustment under vacuumAn adjustment under vacuum is only possible in the lowerpressure range.Evacuate the pressure transducer VSP 3000 to a pressurepreferably below 1*10-3 mbar (e. g. by applying a high vacuumpump).
