Introduction
The Druck DPI 150 high accuracy, single-range pressure indicator uses the
Druck IDOS sensor to produce pressure readings in units of pressure
measurement and aeronautical units.
The instrument is contained in a moulded plastic case with integral rubber
feet for workbench surface use. Function keys, on the front panel, allow the
user to access an operating menu and set-up menu. Two more menus,
supervisor and calibration, allow the user to change the PIN codes,
communications settings and display language and for calibration of the
pressure sensor. A four digit PIN code protects both these facilities. The
electrical and pressure connections are located on the rear panel.
The instrument is supplied, as standard, with a RS232 data interface. Options
available include an IEEE 488 interface, an analogue output, a barometric
reference, negative calibration, external sensor and panel mount kit.

Connections
Note: Switch off the power supply before connecting or disconnecting the
instrument. Isolate the pneumatic supply pressures and depressurise
the pipes before connecting or disconnecting the instrument.
1. Use an appropriate sealing method for all pressure connections.
Method of connection 1/8 BSP (G1/8)
recommended method alternative method below 100 bar
*mandatory method 100 bar and above
Connections for gauge operation Connections for barometric option
2. Before use, make sure the SELV power adaptor supplied with the
instrument is correct for the power supply voltage. The Safety Extra
Low Voltage (SELV) power adaptor complies with EN61010 (including
safety requirements for laboratory instruments).

Using other power adaptors
Responsibility of the User
A power adaptor, not supplied with the instrument, must comply with the
SELV safety requirements of EN61010:
3. Connect the power adaptor to the instrument and switch the power
supply on.
Analogue Output Option
Panel mounting and
A panel mounted instrument must have the rubber feet removed for the side
plates to be secured. The instrument fits into a panel cut-out, the side and
front plates of the panel mount kit (option C) secures the instrument to the
panel. It is important that a panel mount installation provides enough
circulation of air to cool the instrument.

Procedure
To fit this option requires a panel cut-out of the dimensions shown in .
1. Remove the rubber inserts in the feet of the instrument.
2. Unscrew and remove two 45mm screws (2) attaching two feet on one
side of the instrument casing. Retain the two 45mm screws for the
next step.
3. Fit the side plate (1) to the side of the instrument casing and secure
with the two 45mm screws.
4. Repeat steps 2 and 3 for the other side plate.
5. Locate the assembled instrument behind the cut-out panel and align
the four 3.5mm holes in the panel and the holes in the flanges of the
side plates (1).
6. Locate the front plate (3) over the front of the protruding instrument
and secure the front plate with the four screws (4).
Bench stand
The bench stand lifts the front of the instrument providing a better angle of
display and key-pad access for the user.
