General information
To operate the vacuum gauge DCP 3000, at least one external
pressure transducer VSK 3000 or VSP 3000 or MPT 100 is required!
Read and comply with this manual before installing or operating the equip-
ment.
Remove all packing material, remove the product from its packing-box, remove the
protective covers and keep, inspect the equipment.
If the equipment is damaged, notify the supplier and the carrier in writing within three
days; state the item number of the product together with the order number and the
supplier’s invoice number. Retain all packing material for inspection.
Do not use the equipment if it is damaged.
If the equipment is not used immediately, replace the protective covers. Store the
equipment in suitable conditions.
Intended use
☞ OperatethedeviceonlyincombinationwithVACUUBRANDgenuineaccesso-
ries.Makesure thattheindividual componentsareonlyconnected, combined
and operated according to their design and as indicated in the instructions for
use.
☞ Comply with notes on correct vacuum and electrical connections, see section
”Useandoperation”.
• Thedeviceisdesignedforambient and gas temperatures at the pressure trans-
ducerconnectionof+10°Cto+40°Catcontinuousoperation,upto+80°Cfor
short periods (< 5 minutes) at the pressure transducer. If installing the device into
a cabinet or a housing check maximum temperature. Ensure that the maximum
permitted gas temperature at the pressure transducer (see ”Technical data”) is
not exceeded.
Usetheequipmentfortheintendeduseonly,i.e.formeasurementofvacuuminves-
sels designed for that purpose.
Connecting the device
☞Avoid uncontrolled overpressure (e.g., when connecting to a locked or blocked
tubing system). Risk of bursting.
• Comply with max. permitted pressure at the pressure transducer, see section
”Technical data”.
•Connecthosesatthepressuretransducergastight.
• The device is equipped with a short circuit proof wide range power supply
with an integrated overload protection.
•  Checkthatmains voltageandcurrent conformwiththe equipment(seerating
plate).
• Prior to using the wall power supply, assemble and lock the suitable mains plug
(included in delivery) to the power supply.

ments.
When the device is brought from cold environment into a warm room for operation
bedewing may occur. Allow the device to acclimatise.
Complywith national safety regulations and safety requirements concerning the
useofvacuumandelectricalequipment.Complywithallapplicable and relevant

Ambient conditions
To the best of our knowledge the equipment is in compliance with the requirements
of the applicable EC-directives and harmonized standards with regard to design,
typeandmodel,especiallydirectiveEN61010-1.Thisdirectivegivesindetailcon-

Operating conditions
➨The devices are not suitable for applications which involve dangerous or ex-
plosive gases or explosive or ammable mixtures.
Ensure that the materials of the wetted parts are compatible with the substances
processedinthevacuumsystem,seesection“Technicaldata”.

Notes on operation
Operation principle of the VSK 3000
TheVSK3000isequippedwithacapacitivepressuretransducerwithceramicdiaphragmtomeasure
the actual pressure independent of the gas type and depending on the vacuum, i. e. absolute.
Thepressurevalueisdisplayedwitharesolutionof0.1mbarinthepressurerangefrom0.1mbarto
1060mbar.
Operation principle VSP 3000
ThepressuretransducerVSP3000reliesonthefactthatthethermalconductivityoftheresidualgas
in the vacuum chamber is a measure for the gas pressure. The thermal conductivity of gases is propor-
tional to the pressure within a certain range and is related to the molecular mass.
The thermal conductivity of gases and vapours varies with their molecular mass. Therefore the pressure
measurement is dependent on the gas type. The pressure transducer has been adjusted for air at the
factory.
Changing the vacuum connector at pressure transducer VSK 3000
Installing the hose nozzle:
Unscrewtheange(usinga17mmopen-endwrench,ifnecessary)toexposethecompressiontting

General information on handling the VSP 3000
ThepressuretransducerVSP3000whichhasbeendevelopedparticularlyforuseinchemicallaborato-
riesisapressuresensorworkinginthenevacuumrange.Overthewholemeasuringrangethepres-
sure reading is indicated in exponential notation.
AllowtheVSP3000aperiodofapprox.20minutestopreheatandtomeetitsspecications.Evenin
caseofthecontrollerorvacuumgaugebeingswitchedoff,theVSP3000staysreadyforoperation.
Tode-energizethepressuretransducer,unplugeitheritsVACUU•BUSlineorthepowersupplyofthe
controller or vacuum gauge.
Theinteriorofthepressuretransducerishighlysensitive!Donotinsertngersor
tools into the measuring chamber.
VACUU•BUS
Readout of the pressure transducer via VACUU•BUS line by the vacuum gauge DCP 3000 using

Don’t use more than one DCP 3000 within a VACUU•BUS system. MorethanoneDCP3000within
thesameVACUU•BUSsystemwillinterferewitheachotherandcauseerrormessagesoftheconnected

VSK 3000:
☞ The display ashes at a pressure higher than approxi-
mately1060mbar.Immediate pressure release. Risk of
bursting!
VSP 3000:
☞Attention:Maximumpressurereading:1*103 mbar. Pres-
surevaluesabove1000mbararenotdisplayed.Risk of
unnoticed overpressure. Risk of bursting!
Prior to use
➨ Connectthegaugehead VSK 3000orVSP3000withconnecting cable (VACUU•BUS line) toa
socketattherearsideoftheDCP3000.
➨ Connectthegaugeheadtothevacuumchamberviathesmallangeconnection,thehosenozzleor
PTFEtubing.Avoidcontamination(oil/oilmist)ofthegaugeheadwhengeneratingthevacuumwith
anoil-lledvacuumpump.
☞Do not mount the gauge head directly at the oil-sealed pump. The diameter of the pipelines should
be as large as possible.
☞Inside a vacuum system where evaporation occurs (e.g. rotary evaporator) the vacuum is not uniform
(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 ow into it.
VSP 3000:
Recommended orientation: Vertically with vacuum connection pointing downwards. If mounting the
VSP 3000 in any other orientation, a readjustment is recommended (see section ”Readjustment of
VSP3000”).
☞If necessary, clean the gauge head.
➨Switch the equipment on.
Automatic detection of connected components
Whenswitchingonthedevicetheactualcongurationoftheconnectedcomponentsischecked.
Connected components (valves, sensors, etc.) are automatically detected, used and monitored until
thedeviceisswitchedoff.RecongurationispossiblebyswitchingtheDCP3000off/on.Identicalcom-
ponentsmustbeconguredbeforehandtodifferentVACUU•BUSaddresses(e.g.,VSK1andVSK2),
seesection”Connectingseveralpressuretransducers”.
➨ Further information on how to use several sensors or valves on request.
Thecongurationmenuisstoredinthedevice,see”Conguration”withspecicsettingsadaptedauto-
matically to the connected components.
Depending on the connected components (valves, sensors) some menu items are not active!

Measuring differential pressure
A differential pressure between two pressure transducers can only be determined and indicated be-

dress ”Ref. 1”).
☞ In addition, both pressure transducers have to be congured to corresponding VACUU•BUS ad-
