Manual-no.: 999162 // 19/01/2011Measuring differential pressureA differential pressure between two pressure transducers can only be determined and indicated be-tween two pressure transducers VSK 3000 connected to the DCP 3000.☞ This requires one of the two pressure transducers to be defined as reference (e.g., VACUU•BUS ad-dress ”Ref. 1”).☞ In addition, both pressure transducers have to be configured to corresponding VACUU•BUS ad-dresses (VSK x and Ref. x). If the two addresses do not correspond (VSK x and Ref. y), no differen-tial pressure will be determined or displayed. Then it is necessary to reconfigure the address of onepressure transducer to enable differential pressure measurement (see section ”Reconfiguring thepressure transducer”.)➨ The displayed pressure value is: (”pressure value of Ref. x” minus ”pressure value of VSK x”) mbarReconfiguring the pressure transducer VSP 3000 or VSK 3000Configuration of the MPT 100: See instructions for use of MPT 100.Reconfiguring the VACUU•BUS address of a pressure transducer:1. Switch the vacuum gauge DCP 3000 off.2. Preferably connect only the pressure transducer to be reconfigured to the DCP 3000.3. Keep key ”VENT” pressed and switch the DCP 3000 on (key ”ON/OFF”).4. Select the menu item ”Vacuubus” by turning and pressing the selection knob.5. The first component detected by the VACUU•BUS is displayed (e.g., VSK 1). If necessary, select thepressure transducer to be reconfigured by turning and pressing the selection knob.6. Keep key ”VENT” pressed and press selection knob additionally. The inverse display of the compo-nent is replaced by a frame.7. Turn the selection knob until the address, to which you want to reconfigure the pressure transducer(e.g., VSK 2 or Ref.1), is displayed.8. Press the selection knob. If the configuration was successful, the menu is quit and the DCP 3000restarts.A configuration of more than one pressure transducer to the same VACUU•BUS address will result inerror conditions at the DCP 3000 and must therefore be avoided!Do not configure a VSK 3000 as VSP 3000.Do not configure a VSP 3000 as VSK 3000.Further information concerning the configuration of other components (e.g., valves) on demand.
