page 62 of 106The vacuum gauge was adjusted using factory standards,which are traceable through regular calibration in an ac-credited laboratory (German Calibration Service) to theGerman national pressure standard. Depending on theprocess and/or accuracy requirements, check the adjust-ment and readjust if necessary. For readjustment, thedevice has to be adjusted both at atmospheric pressureas well as under vacuum but only if the reference pres-sures are known with certainty. The adjustment mode canbe activated only if the process control is inactive. Press”START/STOP” key, if necessary. In the range between 15to 525 Torr (20 to 700 mbar) no adjustment is possible;---- Torr is displayed.Adjustment 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 CVC3000 and/or the vacuum system. Make surethat the pressure transducer is at atmosphericpressure.➨ In ”Configuration” menu, select program ”Adjustment” at the control-ler.➨ Use the selection knob to adjust the reading to the current atmosphericpressure.➨ Press the selection knob to confirm.1013 mbarNote: 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).Readjustment of CVC 3000NOTICE
