7. Operation
7.1 Operating and display elements
Fig. 2 LC display
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 three miniature push buttons located in
the front.
The menu system is a closed system allowing you to scroll
both forward and backward through the individual set-up
menus to navigate to the desired setting item. All settings
are permanently stored in an EEPROM and therefore
available again even after a battery change.

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.
With certain media, however, the diaphragm may be pollut-
ed or coated with deposit. It is recommended to define
corresponding service intervals for control.. 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 PCE Instruments for
decalcification. Please read therefore the chapter
“Repair”
below.
!
A false cleaning of the device can cause an irreparable
damage on the diaphragm. Therefore never use point-
ed objects or pressured air for cleaning the diaphragm.
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. This form can be provided by PCE
Instruments. If your device came in contact with harmful
substances, a declaration of decontamination is additionally
required. 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 have to be
complied with for purification!
10. Warranty conditions
The warranty conditions are subject to the legal warranty
period of 24 months from the date of delivery. In case of
improper use, modifications of or damages to the device, we
do not accept warranty claims. Damaged diaphragms will
also not be accepted. Furthermore, defects due to normal
wear are not subject to warranty services.
11. Declaration of conformity / CE
The delivered device fulfils all legal requirements. The
applied directives, harmonised standards and documents
are listed in the EC declaration of conformity.
Additionally, the operational safety is confirmed by the CE
sign on the manufacturing label.

13. Disposal
The device must be disposed according to the
European
Directives
2002/96/EG
and
2003/108/EG (on waste electrical and electronic
equipment) Waste of electrical and electronic
equipment may not be disposed by domestic
refuse!
WARNING! Depending on the measuring medium,
deposit on the device may cause danger for the user
and
the
environment.
Comply
with
adequate
precautions for purification and dispose of it properly.

Setting of the decimal point position
Depending on the nominal pressure range and on the set unit, only a limited number of positions after
the decimal point can be displayed.

Along with the unit, the decimal point position has probably to be changed in order to get a correct
indication of the measured value. Besides, depending on the nominal pressure range, perhaps not all
available units can be used.

Calibration of initial point
If you detect a shifting of the measured value deviating from the offset, the display can be re-calibrated. For
this, a pressure reference is necessary if the offset differs from the ambient pressure. The used pressure
must be identical to the starting point of the pressure measuring range. For reading the new pressure into
the device, push the ▲ button.
Please note the following diviation:
-
1 … x bar: the offset is calibrated at -0.9 bar; during calibration we check whether the device will be within
tolerance at -1 bar (in theory); for re-calibration a pressure reference of -0.9 bar is necessary
0 … x bar abs.: the offset is calibrated at 0.1 bar abs.; during calibration we check whether the device will
be within tolerance at 0 bar abs.; for re-calibration a pressure reference of 0.1 bar is necessary
If the re-calibration leads to a worsening of the original calibration, e. g. as a result of a defect pressure
reference, the defaults can be re-set by the menu item "LD FAC" according to your order
9 CAL EP
Calibration of end point
If you detect a shifting of the measured value deviating from the end point, the display can be re-calibrated.
For this, a pressure reference is necessary if the offset differs from the ambient pressure. The used pres-
sure must be identical to the end point of the pressure measuring range. For reading the new pressure into
the device, push the ▲ button.
If the re-calibration leads to a worsening of the original calibration, e. g. as a result of a defect pressure
reference, the defaults can be re-set by the menu item "LD FAC" according to your order.

Load defaults
To load the defaults you have to push the ▲–button. After the action "LOADED" and "OK" appers in the
display for a short time. The configuration mode will be left automatically.
-
▲ / on button:
with this button you turn the device on; in the operating mode you move forward in the menu system or
increase the displayed value
-
▼ / off button:
with this button you turn the device off; in the operating mode you move backwards in the menu system or
decrease the displayed value
-
OK-button:
with this button you enter the operating mode; besides, it is used to activate the different menu items and
to confirm the set values
To configure the different menu items, set the desired values by pushing the "▼" or "▲" buttons. Confirm the setting with the
„OK“ button and the menu item will start blinking to indicate that you can start the configuration.
To save the configured values or to leave a menu item, you also have to push the “OK” button.
Changes of the adjustable parameters become only effective after pushing the OK button and leaving the menu item. After
leaving the menu system, all parameters will be checked against each other and in reference to the characteristics of the
device. If the message "OK" appears in the display for some seconds, the configuration was successfully. If the message
"ERROR" appears, at least one of the set values is out of the permissible range. For example, an error will occur if a device
with a nominal pressure range of 400 bar should be set on 4 positions after the decimal point. If an error has been detect-
ed, the lastly runnable parameters will be set again.
After configuring the unit, the conversion of the pressure range (in menus UPPER and LOWER) into the new unit will only
occur after leaving the complete menu system. Besides, depending on the number of displayed figures of the respective nom-
inal pressure range, probably not all available units (in menu UNIT) can be used.
