Prior to operation
➨ Connect gauge head by means of the VACUU•BUS line to a controller CVC 3000 or VNC 2 or to a
vacuum gauge DCP 3000.
➨ Connect the gauge head to the vacuum chamber by means of the small flange connection or a hose
connection. Avoid contamination (oil/oil mist) of the gauge head when generating the vacuum with an
oil-sealed vacuum pump.
☞ Do not mount the gauge head directly at the oil-sealed pump but close to the vacuum process. The
diameter of the vacuum lines should be as large as possible.
☞ Inside a vacuum system where evaporation occurs (e.g., rotary evaporator) the vacuum is not uni-
form (e.g., a condenser acts as pump or the vacuum in the pipeline is lower than in the system).
Therefore choose carefully the position where to connect the gauge head.
☞ Condensate and deposits at the gauge head falsify the measurement result.
☞ If residues occur or when working with aggressive or condensable substances, install a gas washing
bottle in front of the pressure gauge head.
☞ Mount the gauge head in such a position that condensate can not flow into it.
☞ If necessary, clean the gauge head.
VACUU•BUS
Readout of the pressure transducer via VACUU•BUS line by he controller CVC 3000 or VNC 2 or by
the vacuum gauge DCP 3000 using VACUU•BUS protocol (see instructions for use of vacuum control-
lers CVC 3000 or VNC 2 or of vacuum gauge DCP 3000). Maximum cable length inside buildings: 30m.
Extension cable VACUU•BUS 2m: order-no. 612552.
With the devices CVC 3000 and DCP 3000 it is possible to adjust and to configure the pressure trans-
ducer VSK 3000. (A configuration of the VSK 3000 e.g., to a different VACUU•BUS address, is required
if more than one pressure transducer are connected to a CVC 3000 or DCP 3000.)
Additional instructions for use regarding the configuration of pressure transducers or other
VACUU•BUS components are available upon request.

Installing the PTFE-tubing connection (PTFE-tubing ID: 8mm, OD: 19mm):
Unscrew the flange (using a 17 mm open-end wrench, if necessary) to expose the compression fitting
(1). Slip the compression nut, and then the ferrule, onto the PTFE-tubing (2). Slide the PTFE-tubing onto
the compression fitting on the VSK 3000 gauge head, and tighten the compression nut firmly finger-tight
