ENGLISH
1. Notesonsafety/productselection
1.1 Approveduse
The device is approved for use in applications described in the Operat-
ing Instructions only. Any other use is not approved and can lead to
accidents or the destruction of the device. Non-approved use will result
in the immediate expiry of all guarantee and warranty claims against the
manufacturer.
Serious malfunctions leading to personal injury or damage to
property can result from using the chosen product in applications
that do not comply with the given specications or from disre-
garding the operating instructions and warning notes.
1.2 Skilledpersonnel
These operating instructions have been written for skilled personnel
who are familiar with the valid regulations and standards applicable to
the eld of application.
1.3 Accuracyofthetechnicaldocumentation
These operating instructions were created with the utmost care and at-
tention. However, we offer no guarantee that the data, graphics and
drawings are correct or complete. Subject to alteration without notice.
1.4 High-pressureapplications
Selection
When selecting pressure components, ensure that the overload
pressure will not be exceeded.
It is possible that the pressure cell can be deformed when the
overload pressure is exceeded (depending on the duration/fre-
quency and level of the pressure spike).
The 'diesel effect’ caused by entrapped air can result in pres-
sure spikes that far exceed the overload pressure. The nominal
pressure of the pressure component should be higher than the
nominal pressure of the system to be measured.

Notesonsafety/productselection
Mounting
Please abide by the instructions and observe the correct tight-
ening torques for the ttings or adapters being utilised.
Connector thread: ½" BSP = 90 Nm
¼" BSP = 30 Nm
1.5 Service/repair
For repairs to or calibration of the measurement instruments, please
contact a Webtec sales branch.
1.6 Notesondisposal
RecyclingincompliancewithWEEE
Purchasing our product gives you the opportunity to return the device to
Webtec at the end of its life cycle.
The EU Directive 2002/96 EC (WEEE) regulates the return and
recycling of waste electrical and electronics equipment.
As of 13/8/2005 manufacturers of electrical and electronics
equipment in the B2B (business-to-business) category are
obliged to take back and recycle WEEE free of charge sold after this
date. After that date, electrical equipment must not be disposed of
through the 'normal' waste disposal channels. Electrical equipment must
be disposed of and recycled separately. All devices that fall under the
directive must feature this logo:
Canwebeofassistance?
Webtec offers you the option of returning your old device to us at no ex-
tra charge. Webtec will then professionally recycle and dispose of your
device in accordance with the applicable law.

Notesonsafety/productselection
ENGLISH
Whatdoyouhavetodo?
Once your device has reached the end of its service life, simply return it
by parcel service (in the box) to your Webtec sales branch responsible
for customer care - we will then initiate the necessary recycling and dis-
posal measures. You will incur no costs or suffer any inconvenience.

Deviceversion/rangeofsupply
2. Deviceversion/rangeofsupply
The measuring instrument and sensors enable the user to measure all
relevant parameters in a hydraulic system.
Parameters:
• [bar/psi] Pressure, Dp (load sensing pumps)
• [°C/°F] Temperature
• [L/min/G/min] (U.S) volumetric ow rate
• [1/min] RPM
Automatic sensor recognition means the measuring instrument is simple
to operate. It is not necessary to carry out any further settings to the
device.
Plug & Work is one of the more important attributes of the device. It al-
lows the measuring instrument to be ready to operate in an instance,
and excludes erroneous measurements.

77V2.0/02.11
Initialuse
ENGLISH
3. Initialuse
The measuring instrument is supplied with rechargeable batteries tted
at the factory.
Charge the rechargeable batteries for at least 3 hours before using for
the rst time. The device is then ready for use.
3.1 Chargingthebatteries/batterystatusindicator
If the battery power is too low, the battery symbol ashes and the meas-
uring instrument turns off automatically.
Battery symbol
The measuring instrument is powered using the external power supply
unit or via the car adapter. The battery can be recharged directly. The
recharging process begins as soon as the power supply unit is con-
nected.
► Please refer to the chapter 'Accessories' for more information about
the external power supply unit and the car adapter.

Key assignments and symbols associated with the menu func-
tions are consistent throughout this device; therefore, there will
be no further explicit explanation given.
Whatthefunctionkeysdowithinthemenus
Use the arrow keys to scroll between functions when several functions
are available for selection in a window or a menu. The arrow keys move
the cursor in the direction in which the arrow is pointing.
Press the OK key each time you wish select a function or submenu;
when making alterations or adding values you must press OK to conrm
your action. The OK key is used to save all settings. Press the STOP/
ESC key if you wish to leave a menu or do not wish to save an entry.
Key assignment and mode of operation of these three keys is always the
same no matter in which menu they are used.

Keysandfunctions
ENGLISH
As the function keys are easy to understand and always function
in the same manner, actuating the function keys has not been
included in the example sequences to ensure that the content of
the menus remain central to the descriptions. It is a pre-condition
for replicating the examples that the function keys are used as
described above.
Example: setting the unit (text) and the measurement range (numeri-
cal)
Text input:
to set the units (max. 15 characters)
Numerical input:
to set the measurement range and signal span

(T-adapter). ∆p-calibration sets the tolerance of the sensors in
relation to one another to zero.
This setting remains stored; it is valid only for the respective op-
erating pressure.
