3.1 Unpacking the balance

Precisa balances are delivered in an environmentally-friendly package,
specifically developed for this precision instrument, which provides
optimal protection for the balance during transportation.

In order to avoid damage, attention must be given to the following
points when unpacking the balance:

• Unpack the balance quietly and carefully. It is a precision instru­ment.

• When outside temperatures are very low, the balance should first be
stored for some hours in the unopened transport package in a dry
room at normal temperature, so that no condensation settles on the
balance when unpacking.

• Check the balance immediately after unpacking for externally visible
damage. If you should find transport damages, please inform your
Precisa Services representative immediately.

• If the balance is not to be used immediately after purchase but only
at a later time, it should be stored in a dry place where fluctuations
in temperature are as low as possible (see Chapter 12 “Transport,
storage and disposal”).

• Read through these operating instructions, even if you already have
experience with Precisa-balances, before you work with the balance
and pay attention to the Safety recommendations (see Chapter 1
“Safety”).

NOTE

Retain the original packaging in order to avoid transportation dama­ges when shipping or transporting the balance and to allow the ba­lance to be stored in the best conditions if it is out of operation for
an extended period.

3.3 Assembly of the balance

The balance is delivered in partly dismantled condition. Assemble the
individual components in the following sequence (see fig. 2.1 and
fig. 2.2).

• Install the dust-protection cover on the balance

• Install the windshield as well as the protective ring with the two
screws supplied

• Place the scale-pan holder in position and add the weighing pan

• Insert the power adaptor cable plug into the socket at the rear of the
balance.

3.4 Choice of a suitable location

The balance location must be chosen in such a way as to guarantee
perfect functioning of your balance, so that the allowable ambient
conditions (see Chapter 2.3.1 “Technical data”) are maintained and,
in addition, so that the following prerequisites are met:

• Put the balance on a solid, firm and preferably vibration-proof,
horizontal base

• Make sure that the balance cannot be shaken or knocked over

• Protect from direct solar radiation

• Avoid drafts and excessive temperature fluctuations

NOTE

A screwdriver is required for assembly.
All parts must fit together easily. Do not apply force. Precisa

Customer Service will be pleased to help you with any problems.

NOTE

With difficult environment-conditions (where the balance may be
easily shaken or subject to vibration) the balance can nevertheless
provide accurate results through suitable adjustment of the stability
control (see Chapter 5.7 “Weighing mode”).

■ 3 Starting up

18

3.5 Checking the mains voltage

The following Safety recommendations must be observed when
connecting the balance to the mains:

3.6 Levelling the balance

To function properly, the balance must be precisely horizontal.
The balance is fitted with one “bubble level” and two adjustable feet

for level-control, with the aid of which it is possible to compensate for
small height differences and/or unevennesses in the surface on which
the balance is standing.

The two screw feet must be adjusted so that the air bubble is preci­sely in the centre of the sight glass of the bubble level (see Fig. 3.2
Correct levelling with the aid of the bubble level).

Fig. 3.2 Correct levelling with the aid of the bubble level

DANGER

The balance may only be operated with the power adaptor
supplied.

Check before connecting the power adaptor to the mains supply,
that the operating voltage stated on the power adaptor agrees
with the local mains voltage.

If the operating voltage is not the same as the mains voltage, the
power adaptor must on no account be connected to the mains
supply. Contact the Precisa-Customer Service.

Incorrect Correct

3 Starting up ■

19

3.7 Calibration of the balance

Since the Earth's gravity is not the same everywhere, each balance
must – in accordance with the underlying physical weighing principle
– be adjusted to compensate for the gravity at each location. This
adjustment process, known as “calibration”, must be carried out on
initial installation and after each subsequent relocation. In order to get
exact measurements, it is recommended moreover, that the balance
should also be calibrated intermittently during the weighing operation.

The setting of the calibration is effected in the configuration menu.
Depending on the model of balance, this may be done externally, in­ternally or automatically (see Chapter 5.6 “Calibration functions”).

With the aid of the “Intelligent Calibration Mode” ICM the balance can
itself determine the size of the calibration weight, which enables an
exact calibration with different size weights (in 10 g, 50 g, 100 g and
500 g steps, depending on implementation).

3.8 Dual Range and Floating Range balances

With the Precisa Dual Range balances, weighing is always first carried
out in the small, more exact range. Only when the small range is
exceeded will the balance switch automatically into the bigger range.

The Floating Range balances have a 10-fold more precise fine range,
which is movable over the entire weight range. By pressing the tare
key «T» the fine-area can be called up as often as required over the
entire weight range.

NOTE

In order to get exact measurements, the balance must again be
carefully levelled after each relocation.

NOTE

The balance must be calibrated on initial installation and after every
relocation.

If you work in accordance with “Good Laboratory Practice GLP” ob­serve the prescribed intervals between calibrations (adjustments).

■ 3 Starting up

20

3.9 Standardized balance

The standardized balances of the Precisa XB-Series are provided with
the EU/OIML licence or meet the local standardisation regulations.

The balance program and certain functions of the weighing output
differ from the standard program in the case of the standardized XB
balances – in accordance with the EU/OIML provisions.

3.10 Under-floor weighing

Objects which, because of their size or shape, cannot be put on the
scale, can be weighed by means of under-floor weighing.

Proceed as follows:

• Turn off the balance.

• Remove the scale-pan and the scale-pan support and turn the balan­ce around.

• Push the metal-cover (1) on the floor of the balance to one side.

• Hang a small hook (available as an accessory, see Chapter 13 “Ac­cessories”) into the aperture (3) of the now visible metal casting (2).

• Place the balance over an opening.

• Replace the scale-pan support and the scale-pan.

• Level the balance (see Chapter 3.6 “Levelling the balance”).

• Switch on the balance.

NOTE

If a circle appears in the main-display of a standardized balance, so
the indicated value is unstandardised.

In balances of class (1) the circle also stands for the warm-up
phase.

Your Precisa Customer Service will be happy to assist you at any
time if you have any questions on the standardization of the balan­ce or on working with standardized balances of the XB-Series.

• Hang the object to be weighed on the hook and carry out the
weighing.

Fig. 3.3 Setting up the balance for under-floor weighings

CAUTION

Take care that the hooks used for the under-floor weighing are
stable enough to hold the goods which you wish to weigh.

NOTE

Take care that no dirt or moisture can get into the balance with the
scale-pan carrier removed.

After completing the under-floor weighing, the opening in the floor
of the balance must be closed again (dust protection).

4.6.3 Display

The balance display has two lines (1 and 2).

Fig. 4.2 Display

The upper display-line (1) includes the 8-figure measurement display
(3) as well as various symbols (4).

The lower line (2) serves as a 20-character info-line in connection with
the cursor keys for controlling the working programs.

4.7 Password protection of the menus

The two main menus of the balance can be protected by a freely
selectable, four-figure password against unintentional changes.

• With password protection deactivated, any operator can change the
balance configuration and application menus.

• With “standard” password protection activated, only the configura­tion menu is protected against unintentional changes.

• With “high” password protection activated, both the configuration
menu and the application menu are protected against unintentional
changes. Only after entering the correct, four-figure password can
changes be made to the configuration menu and the application
menu.

4.8 Anti-theft encoding

The balance can be protected against theft by a freely selectable,
four-figure numerical code:

• With anti-theft encoding deactivated, the balance can be switched
on again and operated after interruption of the power supply
without entering a code.

• With anti-theft encoding activated, the balance requires the entry of
the four-figure code after each interruption to the power supply.

• If the code is input incorrectly, the balance is blocked.

• If the balance is blocked, it must first be disconnected from the
power supply, then reconnected and unblocked by entering the
correct four-figure code.

• After seven consecutive incorrect entries the display will read “NO
ACCESS, CALL SERVICE”. In this case, only Precisa Service can
unblock the balance again.

To activate the anti-theft encoding and to alter the code programmed
in the works to one which you have chosen yourself, see
Chapter 5.11 “Anti-theft encoding”.

NOTE

The password protection is deactivated at the works.

The pre-programed password set in the works is: 7 9 1 4
This password is the same for all Precisa balances and is always

valid, in parallel with a self-selected password.
Make a note of your personal password.

NOTE

The anti-theft-encoding is deactivated in the works.

The pre-programmed code set by the works is: 8 9 3 7
This code is the same for all Precisa balances. For reasons of

security you should therefore always select your own code.
Keep your personal code in a safe place.

11 Maintenance and servicing

The balance must be treated carefully and cleaned regularly. It is a
precision instrument.

Regularly dismantle the weighing pan and the weighing pan holder and
remove any dirt or dust from under the weighing pan and on the
balance housing with a soft brush or a soft, lint-free cloth, moistened
with a mild soap solution.

The scale and the holder can be cleaned under running water. Take
care that both parts are completely dry, before they are re-installed on
the balance.

The regular maintenance of the balance by your Precisa Service
Representative will guarantee unrestricted functioning and reliability
over many years and will extend the lifespan of the balance.

DANGER

For maintenance-work, the balance must be separated from the
power supply (remove power adaptor plug from socket). Also
ensure that the balance cannot be reconnected to the power
supply during the work by a third party.

Take care during cleaning that no liquid penetrates into the
appliance. If liquid is spilt on the balance, the latter must immedia­tely be disconnected from the electricity supply. The balance may
only be used again after it has first been checked by a Precisa
Service Engineer.

The connections on the rear of the appliance and the power
adaptor may not come into contact with liquids.

CAUTION

Never use solvents, acids, alkalis, paint thinners, scouring pow­ders or other aggressive or corrosive chemicals for cleaning, since
these substances attack the surfaces of the balance housing and
can cause damage.

■ 12 Transport, storage and disposal

12 Transport, storage and disposal

12.1 Transportation and shipping of the balance

Your balance is a precision instrument. Treat it carefully.
Avoid shaking, severe impacts and vibration during the transportation.
Take care that there are no marked temperature fluctuations during

the transportation and that the balance does not become damp
(condensation).

12.2 Storage of the balance

If you would like to take the balance out of service for an extended
period, disconnect it from the electricity supply, clean it thoroughly
(see Chapter 11 “Maintenance and servicing”) and store it in a place
which fulfils the following conditions:

• No violent shaking, no vibrations

• No large temperature fluctuations

• No direct solar radiation

•No moisture

NOTE

The balance should preferably be dispatched and transported in the
original packaging to avoid transportation damage.

NOTE

The balance should preferably be stored in the original packaging,
since this provides optimal protection for the balance.

14.1 Notes on the Weighing mode

14.1.1 Set Weighing mode: FLOATINGDISPLAY

The value set for FLOATINGDISPLAY defines the period, after which
each new measurement is displayed.

For the definition of this period, the quality of the balance-location is
crucial. The stability control must also be suitably chosen.

Recommended values:

14.1.2 Set Weighing mode: Stability control

The value set for the stability control depends on the quality of the
balance location and must be correctly chosen in order to obtain
optimal, reproducible results. Choose:

• “HIGH STABILITY” at an optimal balance location,

• “MEDIUM STABILITY” at a good balance location or

• “LOW STABILITY” at a critical balance location

• Optimal balance location: FLOATINGDISPLAY 0.04 or
FLOATINGDISPLAY 0.08

• Good balance location: FLOATINGDISPLAY 0.16

• Critical balance location: FLOATINGDISPLAY 0.32

NOTE

The value of the Floating Display is a function of the stability con­trol and the balance location. For balance location, see Chapter 3.4
“Choice of a suitable location” and Chapter 5.7 “Weighing mode”.

■ 14 Further information

64

14.1.3 Set Weighing mode: Auto-Standby

The Auto-Standby mode turns off the balance automatically, if:

• the balance is tared and has shown “Zero” for at least 5 minutes

• the balance has received no remote control command via the inter­face for at least 5 minutes,

• the automatic zero correction “Auto-Zero” is activated.

It is possible to start the balance again after it has been switched off
by an automatic Auto-Standby:

• Briefly depress any key

• Put a weight on the scale

• Give a remote control command via the interface

14.1.4 Set Weighing mode: Auto-Zero

If the automatic zero correction “Auto-Zero” is activated, the balance
always gives a stable zero (e.g. even with room temperature fluctua­tions).

14.2 Notes on calibration

The calibration of the balance is fixed in the configuration menu (see
Chapter 3.7 “Calibration of the balance” and Chapter 5.6 “Calibration
functions”).

Possible types of calibration, depending on the model of balance:

• External calibration by means of ICM (Intelligent Calibration Mode)

• External calibration with freely selectable weight

• Internal calibration

• Automatic calibration

NOTE

The calibration can be interrupted at any time by pressing
«ON/OFF».

14 Further information ■

65

14.2.1 External calibration by means of ICM

Depending on the type of balance, calibration weights in steps of
10 g, 50 g, 100 g and 500 g can be used, where the calibration
weight must correspond to the precision of the balance.

For an external calibration by means of ICM, “SET CALIBRATION
MODE EXTERNAL” must be selected in the configuration menu (see
Chapter 5.6 “Calibration functions”).

14.2.2 External calibration with freely selectable weight

For an external calibration with user-definable weight, “SET CALIBRA­TION MODE EXT. -DEF.” must be selected in the configuration menu
(see Chapter 5.6 “Calibration functions”).

Then, the effective value of the calibration weight (DEF. n'nnn g) must
be entered with up to tenfold precision compared with the balance.

• Switch to “BALANCING” with the
«MODE»-key

Then proceed as follows:

14.2.3 Internal calibration

For an internal calibration with the built-in calibration weight “SET
CALIBRATION MODE INTERNAL” must be selected in the configura­tion menu (see Chapter 5.6 “Calibration functions”).

Then proceed as follows:

• Switch to “BALANCING” with the «MODE»-key

•Press «T» until “CALIBRATION” is shown.

• The calibration is finished after a certain period of time.

• Switch to “BALANCING” with the
«MODE»-key

display flashes with the previous­ly entered calibration weight

• Place the calibration weight on
the pan

- - 372 9

• The display flashes rapidly

• Calibration is complete when the
display stops flashing (the exact
weight is shown)

+ 372.15 9

14 Further information ■

67

14.2.4 Automatic calibration

For an automatic calibration with the built-in calibration weight “SET
CALIBRATION MODE AUTO” must be selected in the configuration
menu (see Chapter 5.6 “Calibration functions”).

The balance now calibrates itself automatically every 24 hours and/or
after each temperature change of 3 degrees Celsius, depending on the
definition in the configuration menu “SET CALIBRATION AUTOCAL”.

The time of the automatic calibration is as determined in the configu­ration menu under “SET CALIBRATION AUTOCAL. -TIME n h”.
(e.g. 6 h for 06.00 o'clock in the morning).

NOTE

For the automatic calibration by time and by time/temp. the date
and time of the balance must first be correctly set (see Chapter 5.9
“Date and time”).

The calibration can also be effected manually any time while auto­calibration is activated.

The automatic calibration then takes place only if no weight is pla­ced on the pan for at least five minutes.

It is recommended, that the time for the auto-calibration be set at
a time outside the normal business hours (for example, in the early
morning).
