Notes on operation
(1)
➨ Connect the cable to the vacuum gauge head‘s serial in-
terface and to one the VACUU•BUS sockets (1) at the rear
of the vacuum gauge DCP 3000.
Attention: Do not cant when assembling or removing
plug connections! Comply with correct positioning of
the plug.
☞ Only connect/disconnect the cable to/from the vacuum
gauge head when it is off circuit. Separate the DCP 3000
from mains.
➨ Switch the DCP 3000 on.
When switching on the DCP 3000, a connected vacuum gauge head MPT 100 is automatically detected.
The vacuum gauge head is displayed as active sensor in the status line of the vacuum gauge as MPT
100. Over the whole measuring range the pressure reading is indicated in exponential notation.
Once all cables are connected, the vacuum gauge head MPT 100 is ready to operate. Allow the MPT
100 a stabilization time of approx. 5-10 minutes to meet its specifications. Even in case of the vacuum
gauge being switched off, the MPT 100 stays ready for operation. To de-energize the pressure vacuum
gauge head, unplug either its VACUU•BUS line or the power supply of the vacuum gauge.
The interior of the vacuum gauge head is highly sensitive! Do not insert fingers or
tools into the measuring chamber.
☞ The measured pressure is dependent on the gas type (see ”Notes on operation”).
Max. permitted pressure at the pressure transducer: 1.5 bar (absolute).
☞
Attention: Maximum pressure reading: 1*10 3 mbar. Pressure values above 1000
mbar are not displayed. Risk of unnoticed overpressure. Risk of bursting!
NOTICE
Connecting several pressure transducers
At most, one vacuum gauge head MPT 100 can be connected to the vacuum gauge DCP 3000 from
software version 2.03 and up to four MPT 100 from DCP 3000 software version 2.22. However, it is pos-
sible to connect additionally several external pressure transducers VSK 3000 or VSP 3000 simultane-
ously to the DCP 3000.
Only the readings of one pressure transducer are displayed at a time.
☞
The VACUU•BUS address of the active and displayed pressure transducer is shown in the upper left
corner (status line). The readings of all pressure transducers are shown in the menu ”Sensors” (see
instructions for use of DCP 3000).
☞ Each pressure transducer needs an individual address (VSK 1 to VSK 4 / MPT 1 to MPT 4 (replacing
VSP 3000 if connected) / VSP 1 to VSP 4) to communicate with the DCP 3000 via VACUU•BUS.
☞ Factory set each pressure transducer is set to address “1”.
To use several pressure transducers it is necessary to configurate the transducer appropriately.
