Introduction
The Druck DPI 104 is a digital pressure indicator that
measures the pressure of liquid, gas or vapour and shows
the pressure value on a liquid crystal display (LCD). It also
has the Intelligent Digital Output Sensor (IDOS) technology
to use data from a Universal Pressure Module (UPM).
The DPI 104 includes these functions:
Function
* Measure pressure - Accuracy: 0.05% full scale (FS)
Large 5-digit main display with 11 pressure units
Adjustable Full Scale Output (FSO)
20 segment analogue dial in increments of 5% FSO
(large division marks = 10% increments).
2.5 digit percentage indicator (0 -100% FSO)
8-pin connector port: For RS232, **IDOS UPM, external power
supply
Alarm output for high/low pres sure conditions
Switch input to monitor an external pressure switch
Analogue voltage output (Vout): 0 - 5 Vdc
Other functions: Maximum/minimum, tare, Vout scale factor,
automatic power off
* Refer to “Specification data”.
** Optional item
Safety
Before you use the DPI 104, make sure that you read and
understand all the related data. This includes: all local
safety procedures, and this publication.
• Some liquid and gas mixtures are dangerous. This
includes mixtures that occur because of
contamination. Make sure that the DPI 104 is safe to
use with the necessary media.
• It is dangerous to ignore the specified limits for the
DPI 104 or to use the DPI 104 when it is not in its
normal condition. Use the applicable protection and
obey all safety precautions.
• To prevent a dangerous release of pressure, isolate
and bleed the system before you disconnect a
pressure connection.
• Do not use the DPI 104 in locations with explosive
gas, vapour or dust. There is a risk of an explosion.
Before you start an operation or procedure, make sure
that you have the necessary skills (if necessary, with
qualifications from an approved training establishment).
Follow good engineering practice at all times.

Maximum/minimum mode - On.
IDOS UPM mode - On. To monitor pressure from a UPM
16. Low battery power indication: Battery life ≤ 15%.
To start - Prepare the instrument
Before you use the instrument for the first time:
• Make sure that there is no damage to the instrument,
and that there are no missing items.
• Install the battery (refer to “Installation”). Then
re-attach the display bezel [A1: item 6].
To start - Power on or off
Press the buttons in the sequence shown below.
•Power on sequence:
1
First display =
FS limit
Then:
Normal output
• Power off sequence:
Normal output 1 Menu: 2
OFF
(For 2 sec onds)
When the power is of f, the last set of c onfiguration options
stays in memory.
Note: The DPI 104 uses a small quantity of power while it is
OFF. If you put it into storage for a long period, disconnect
the battery (refer to “Installation”).
