determined and indicated between two VSK 3000 pressure transducers

connected to the DCP 3000.

+ This requires one of the two pressure transducers to be dened as

reference (e.g., VACUU•BUS address ”Ref. 1”).

+ In addition, both pressure transducers have to be congured to cor-

responding VACUU•BUS addresses (VSK x and Ref. x). If the two ad-

dresses do not correspond (VSK x and Ref. y), no differential pressure

will be determined or displayed. Then it is necessary to recongure

the address of one pressure transducer to enable differential pressure

measurement (see section ”Reconguring the pressure transducer”

below).

➨ The displayed pressure value is: (”pressure value of Ref. x” minus

”pressure value of VSK x”) Torr

Reconguring the pressure transducer VSP 3000 or VSK

3000

Conguration of the MPT 100: See instructions for use of MPT 100.

Reconguring 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 recongured to

the DCP 3000.

3. Keep the ”VENT” key pressed and switch the DCP 3000 on (”ON/

OFF” key). Release the ”VENT” key.

4. Select the menu item ”Vacuubus” by turning and pressing the selec-

tion knob.

5. The rst component detected by the VACUU•BUS is displayed (e.g.,

VSK 1). If necessary, select the pressure transducer to be recong-

ured by turning and pressing the selection knob.

6. Press the ”VENT” key and keep pressed, then press additionally the

selection knob. A frame will replace the inverse display of the compo-

nent. Release the ”VENT” key.

7. Turn the selection knob until the address, to which you want to recon-

gure the pressure transducer (e.g., VSK 2 or Ref.1), is displayed.

8. Press the selection knob. If the conguration was successful, the menu

is left and the DCP 3000 will restart.
