page 54 of 64The vacuum gauge was adjusted using factory standards,which are traceable through regular calibration in an ac-credited laboratory (DAkkS calibration laboratory) to theGerman national pressure standard. Depending on theprocess and/or accuracy requirements, check the adjust-ment and readjust if necessary. For readjustment, the de-vice has to be adjusted both at atmospheric pressure aswell as under vacuum but only if the reference pressuresare known with certainty. In the range between 15 to 525Torr (20 to 700 mbar) no adjustment is possible;”---- Torr” is displayed.Readjustment of VSK 3000NOTICEAdjustment at atmospheric pressureAn adjustment at atmospheric pressure is onlypossible if the pressure is higher than 525 Torr(700 mbar).➨ Vent the measurement connection of the connected external gaugehead VSK 3000. Make sure that the pressure transducer is at atmo-spheric pressure.➨ In ”Configuration” menu, select program ”Adjustment” at the DCP 3000.➨ Use the selection knob to adjust the reading to the current atmosphericpressure.➨ Press the selection knob to confirm.760 TorrNote: To determine the actual atmospheric pressure, use an accuratebarometer or get accurate reading from the weather service, or a nearbyairport or other reliable source (taking into account the difference in alti-tude between the source and the laboratory).
