1. Forward
Thank you for the confidence that you have shown in SUKU by purchasing the digital
manometer.
Like all other SUKU products the digital manometer are a combination of customer
requirements, state-of-the-art technology, modern manufacturing and stringent quality
control.
The SUKU digital manometer described in the operating instructions is designed and
produced in line with the most recent developments. All components are subject to the
strictest quality criteria during production.
These operating instructions have been compiled with care. However, it is impossible to
take every possible usage case into consideration. For this reason, if you feel that
instructions for your particular usage case are missing, please contact SUKU, and we
would be pleased to provide assistance. Please observe the relevant national safety
regulations during the installation, start-up and operation of this temperature switch (e.g.:
VDE 0100).
Scope
These instructions apply to the 3321, 3322 series of digital manometers. Distinctions are
drawn between the 3321 and 3322 models in the individual sections.
The state of technology at the time of delivery always applies. SUKU reserve the right to
make technical changes without notice.
Copyright
All rights to these operating instructions are reserved. These operating instructions,
including extracts thereof, must not be copied or translated into other languages without
written permission.
Safety instructions and warnings
Please read these instructions before installing and starting up the digital manometer.
Failure to follows the instructions will make all guarantee, warranty and compensation

is not permitted.
2. Digital manometer description
The digital manometer is available in two versions (type 3321 and 3322) for the most
varied areas of use.
The digital manometer offers the user numerous measuring units (bar, psi and MPa).
Additional functions such as MIN/MAX memory, tare adjustment plus bar graph with
trailing pointer function round of the digital manometer’s profile. The programmable
parameters are adjusted by means of user-friendly keys on the front.
Correct purpose of use
The equipment is only authorised for proper use for its correct purpose. Failure to do this
will invalidate all warranties and release the manufacturer from all responsibility!
The equipment is constructed in compliance with IP65 and should be protected from
excessive amounts of water and dust.
The equipment must be installed so that it is protected from external damage.
It must be ensured that the manometer is correctly installed and has the relevant IP
protection.
The limits specified in the data sheet must be complied with.
3. Commissioning
Installation
The digital manometer must be connected to the pressure tapping point in a suitable
manner using your own tools. In this case there must be no occurrence of pressure which
exceed the device’s maximum pressure values. Pressures which exceed the digital
manometer’s maximum range can lead to permanent damage to the measuring device.

8. CE - Conformity
The manometer complies with all requirements of EN 61 326 with regard to interference
emission and immunity for use in industrial areas. SUKU recommend the use of shielded
cables. Installation and cable routing must be carried out correctly in order to maintain the
effective protection from electromagnetic interference.
9. Maintenance
The digital manometer that are described in this document are maintenance free. The
equipment will also operate in a stable state for long periods, meaning that regular
adjustment or the like is not required.
10. Troubleshooting
No modifications must be made to the equipment. Only the manufacturer is allowed to
repair the device.
11. Cleaning
The exterior of the digital manometer can be cleaned using a soft, moistened cloth. Heavy
soiling can be removed using a mild cleaning agent.
12. Disposal
The packaging and used parts must be disposed of in accordance with the regulations of
the country in which the device is installed.

Voltage supply
The digital manometer is operated with 2 Mignon AA batteries. A flashing battery symbol
appears on the display screen if the battery charge is low and the batteries should then be
replaced as soon as possible. Open the battery compartment lid on the back of the digital
manometer. Replace the batteries with 2 new Mignon cells. Replace the battery
compartment lid.

Tare function 3322
In this mode the positive deviation of the measured value from the tared value (max. 20%
of the measuring range) is constantly indicated by the main display. The untared pressure
value is always shown on the bar graph display. Thus the digital manometer’s actual
working load can be read off even if the tare function is active. When the tare function is
active, a function indicator appears on the display. There are 2 possible ways of
activating this mode.
1) Select the tare function and set the value to be tared using the keys . When set, the
measured value to be tared is back up as tare. The main display and the auxiliary display
then show the value “0000” in the unpressurised state. Example: if a value to be tared is
set as 2 bar, the main display indicates 0 bar in the unpressurised state.
2) Load the digital manometer with the pressure to be tared. The current measured value
appears in the main display field of the main display. Select the tare function and then
operate both keys simultaneously . The current measured value will be backed up as
tare. The main display and the auxiliary display are set to (0000).
Setting the tare value to (0000) resets the tare function in both models.

- Resets min. value to „0“
Min / Max Memory
The min/max memory is updated with the current measured value in every measuring
cycle.
The min. value is displayed by pressing the min. key.
The max. value is displayed by pressing the max. key.
Pressing and holding the appropriate key (min. or max) and quickly pressing the menu key
at the same time resets the device to the current measured value.
Bar Graph with trailing pointer function
The integrated bar graph display with trailing pointer function additionally indicated on the
display shows the trend in current working pressure directly regardless of the digital
display. With the help of the trailing pointer function, the max stored value is also indicated
in the bar graph display in addition to the digital display in the form of a bar segment. This
bar segment is also updated to the current measure value when the min/max value is
reset.
