3.8 Positioning of the display module
The display module of the pressure gauge is rotatable so
that clear readability is guaranteed even on unusual
installation positions.

4. Initial start-up
WARNING! Before start-up, the user has to check for
proper installation and for any visible defects.
WARNING! The device can be started and operated by
authorized personnel only, who have read and under-
stood the operating manual!
WARNING! The device has to be used within the
technical specifications, only (compare the data in the
data sheet)!
5. Operation
5.1 Operating and display elements
Abb. 3 LC-Display
Select / ON-button:
- switch-on of the device
- choosing of the pressure units
- calibration of starting point
- configuration of the switch-off automatic
Function / OFF-button:
- switch-off of the device
- scrolling in the menu system
The indication of the measured value as well as the
configuration of the individual parameters occurs menu-
driven via the LC display. The individual functions can be set
with the help of two miniature push buttons located in the
front.
The menu system is a closed system allowing you to scroll
forward through the individual set-up menus to navigate to
the desired setting item. All settings are permanently stored
in an Flash-EPROM and therefore available again even after
a battery change.

After configuring the unit, the conversion of the pressure range into the new unit will only occur after leaving the menu
system. Depending on the pressure range, probably not all available units can be used.
6. Supply / changing the batteries
The digital pressure gauge is supplied by a 3 V lithium-
battery (type CR 2450). Stored values/parameters are also
kept after changing the battery.
If the symbol for low batteries is indicated in the display,
it is necessary to replace them as soon as possible with
two new ones of the same type in order to ensure a good
readability of the values. This has only to be done in

The battery case is located in the removable display of the
digital pressure gauge DM 10 / DM 17.

To change the battery goes ahead as follows:
- Remove the cap and change the battery.
- Lock the device after that properly.

Make sure that the batteries are connected correctly
with the corresponding contacts in the battery tray.
Never try to charge batteries, demount them, or

7. Placing out of service
WARNING! When dismantling the device, it must
always be done in the depressurized and currentless
condition! Check also if the medium has to be drained
off before dismantling!
WARNING! Depending on the medium, it may cause
danger for the user. Comply therefore with adequate
precautions for purification.
8. Maintenance
In principle, this device is maintenance-free. If desired, the
housing of the device can be cleaned when switched of
using a damp cloth and non-aggressive cleaning solutions.
Depending on the measuring medium, however, the
diaphragm may be polluted or coated with deposit. If the
medium is known for such tendencies, the user has to set
appropriate cleaning intervals. After placing the device out of
service correctly, the diaphragm can usually be cleaned
carefully with a non-aggressive cleaning solution and a soft
brush or sponge. If the diaphragm is calcified, it is
recommended to send the device to BD SENSORS for
decalcification. Please read therefore the chapter "Repair"
below.
!
An incorrect cleaning can cause irreparable damages
on diaphragm. Never use spiky objects or pressured air
for cleaning the diaphragm.
Minimum pressure display
The minimum pressure during the measurement process will be shown in the display.
To delete the stored value push the Select/ON-button. It appears
been recessed.
Maximum pressure display
The maximum pressure during the measurement process will be shown in the display.
To delete the stored value push the Select/ON-button. It appears
been recessed.
Setting of the pressure unit
Possible units are: bar, mbar, psi, MPa, mH
The desired unit may be selected and activated with the Select/ON-button.
Depending on the nominal pressure range and the accuracy of the device, perhaps not all available
units could be used.
Zero point
If you detect a shifting of the measured value deviating from the offset, the display can be re-calibrated via
pushing the Select/ON-button. The display shows

9. Return
Before every return of your device, whether for recalibration,
decalcification, modifications or repair, it has to be cleaned
carefully and packed shatter-proofed. You have to enclose a
notice of return with detailed defect description when
sending the device. If your device came in contact with
harmful substances, a declaration of decontamination is
additionally required. Appropriate forms can be downloaded
from our homepage www.bdsensors.com. Should you
dispatch a device without a declaration of decontamination
and if there are any doubts in our service department
regarding the used medium, repair will not be started until an
acceptable declaration is sent.
If the device came in contact with hazardous
substances,
certain
precautions
complied with for purification!
10. Disposal
The device must be disposed according to the
European
Directives
2002/96/EG
2003/108/EG (on waste electrical and electronic
equipment). Waste of electrical and electronic
equipment may not be disposed by domestic
