2. BASIC INFORMATION
2.1. Intended use
The purchased balanced serves to determine the weighing value of loads in
laboratory environment. It is intended for application as a non-automatic
weighing instrument only, i.e. the material to be weighed is manually and
carefully placed in the centre of the weighing pan. Weighing result should be
read only after stable reading has been obtained.
2.2. Inappropriate use
Do not use the balance as a dynamic weighing instrument. Even if small
quantities of weighed material are added or removed from the weighing pan of
the instrument, the reading should be taken only after stabilisation of the
measurement results. Do not place any magnetic materials on the weighing
pan, as this can cause damage to the measuring system of the instrument.
Be sure to avoid impact shock and overloading the balance in excess of the
prescribed maximum measuring range (max capacity), minus any possible tare
weight that has been applied.
Never use the balance in an environment where explosion is possible. This
balance has not been adjusted for operation in explosive areas.
There must not be any modification made to the balance.
2.3. Warranty
Warranty is invalid for the following:
• non- observation of the guidelines of this user manual,
• use of the balance other than specified in this manual,
• alteration to or opening of the device,
• mechanical damage and damage caused by media, water, wear and
tear,
• inappropriate assembling or defects of electric installation,
• overloading of the measuring instrument.
- 15 -
2.4. Monitoring the metrological parameters of the instrument
Metrological characteristics of the balance require periodical inspection to be
carried out by its user. Inspection frequency is dependent on ambient
conditions in which the balance is used, types of performed processes and
accepted quality management system in organisation.
2.5. Data included in this user manual
Please read the user manual carefully before assembling and start-up, even if
the user is experienced with this type of weighing instruments.
2.6. Staff training
This balance should only be operated and maintained by personnel who is
trained and experienced in using this type of balances.
3. TRANSPORT AND STORAGE
3.1. Delivery check
Please check the packaging immediately upon delivery and the device during
unpacking for any visible signs of external damage.
3.2. Packaging
Please retain all parts of the original packaging should the balance be
transported in the future. Only the original packaging should be used for
shipping the balance. Before packing, disconnect all attached cables and
remove any loose/movable parts (weighing pan, anti-draft shield, etc.). Please
place balance and its components in their original packaging, and protect them
against damage during transport.
- 16 -
4. UNPACKING, ASSEMBLING AND START-UP
4.1. Assembling and place of use
• The balance should be stored and used in locations free of vibrations and
shakes, free of air movement and dust,
• ambient air temperature should not exceed the range of: +10 °C ÷ +40 °C,
• ambient relative humidity should not exceed 80%,
• during balance operation, ambient temperature in the weighing room should
not change more than 3°C within one hour,
• the balance should be located on a stable wall console desk or a stable
working table which is not affected by vibrations and distant from heat
sources,
• take special precaution when weighing magnetic objects, as part of the
balance is a strong magnet. Should such loads be weighed, use under hook
weighing option, which removes the weighed load from area influenced by
the balance’s magnet. For assembling the hook for under hook weighing
option see the bottom section of balance’s housing,
• in order to avoid the influence of static electricity on the measurement
process, ground the balance’s housing. The grounding bolt is located at the
back of the balance’s housing.

Balance APP
Remove the adhesive tape. Carefully remove the balance from its packaging.
Remove all the elements necessary for correct operation from the accessory
box.
APP 10.R1 and APP 10.R2 balances are equipped with 2 weighing pans which
can be used in turns. It must be remembered that balance activation is only
possible with one weighing pan assembled at a time. Attempt of activating the
balance with two weighing pans assembled simultaneously will result in display
of an “-LH-“ error. In such case one of the pans needs to removed.
Carefully take the balance out of the packaging, remove transport protective
elements and gently place the balance onto its workplace.
• Remove the weighing pan and remove transport protective elements as
shown in the picture above (if these elements are attached).
• After the unpacking of the balance unscrew the bolt (1) which blocks the
calibration mechanism.
- 21 -
• Assemble the weighing pan (for APP 10.R, one of the pans only).
• Make sure the weighing pan is placed properly on the shock absorbers:
the weighing pan cannot touch the housing and should be stable.
• Place the balance at the workplace.
• Levell the balance (see the instruction below).
• Using the wrench (3), after adjusting the balance level (see below); tighten
the bolt (2) on the foot (1) to the balance’s footing until the point of
resistance. Repeat the activity for each foot of the balance.
• After removing the protective elements of the weighing pan and after
unblocking the internal calibration mechanism (only R2 series balances),
plug the indicator into the port which is on the back of the housing. Next,
plug in all the additional devices. Only then can the balance be connected
to mains (the power port is located at the back of the balance’s housing).
- 22 -
4.3. Levelling
Before plugging to mains, level the balance by turning the
adjustable feet in a way that the air bubble of the level is in
its central ring. The balance should be placed at the
workplace firmly on all of its feet.
4.4. Cleaning
Balance should be cleaned with damp cloth by gentle wiping smudges of dirt.
Cleaning of the weighing pan when assembled may cause damage of the
measuring system of the balance. Hence, it is crucial to remove it from the
balance before cleaning.
In order to clean the glass walls of the draft shield of the XA R2 and AS R2
series balance, it is acceptable to remove the walls of the draft shield following
the below instruction.
Steps for XA.R2 series balance:
1. Twist off and remove the top glass wall safety frame, and slide the top
glass wall out of the slideway
- 23 -
2. Remove the back glass wall.
- 24 -
3. Remove the side glass walls. The side glass walls are not replaceable,
so it is important to remember which one is left and right, and after
cleaning install them back properly in the draft shield.
4. CAUTION: do not remove the front glass wall.
5. Remove the weighing pan, the weighing pan safety rings and the
bottom metal plates, so as not to damage the balance mechanism durin
the cleaning.
Thus prepared draft shield and glass walls can be properly cleaned. All the
operations should be done carefully. Pay special CAUTION to the place
where the weighing pan was installed: dirt and other small elements might
enter the balance construction through this openiing, which might negatively
influence the balance parametres.
Upon completion of the cleaning proces reassembly the balance. To do it
repeat steps 1-5 in a reverse order. Be especially careful while assembling
side glass walls, they must take the right place. While sliding the glass
back onto its place remember to pull the protection (like before
when disma ntling the draft shield).

Thus prepared draft shield and glass walls can be properly cleaned. All the
operations should be done carefully. Pay special CAUTION to the place
where the weighing pan was installed: dirt and other small elements might
enter the balance construction through this openiing, which might
negatively influence the balance parametres.
- 27 -
4.5. Plugging to mains
Balance can be connected to mains only with a power adapter that
comes standard with the balance. Nominal power supply of the power
adapter (specified on the data plate of the power adapter) should be
compatible to the power from mains.
Plug the balance to mains – the plugging socket is located at the back of
balance housing.
The test of the display unit takes place after connecting to the power (all the
elements and pictograms are backlit for a short time). Next, the name and the
program number appears consequently, the indication will reach ZERO level
(with reading unit depending on the b
alance). During the process of starting the balance, the test of the internal
mass adjustment mechanism occurs (single location and elevation of the
internal mass adjustment).
If the indication is different from zero, please press
button.
CAUTION: If the balance is “verified”, automatic adjustment/calibration occurs
right after it has been switched on.
4.6. Connecting additional equipment
It is inevitable to plug the computer out of the main before connecting additional

5. BASIC FUNCTIONS
• functions related to measuring units
- weighing in grams [g],
- weighing in milligrams [mg] (in balances with d≤0.001g),
- weighing in kilograms [kg] (in balances with d≥0.01g,
- weighing in carats [ct],
- weighing in units from beyond SI (available only in non-verified
instruments):
[lb], [oz], [ozt], [dwt], [tlh], [tls], [tlt], [tlc], [mom], [gr], [ti], [N], [baht], [tola]
• functions related to working modes
- counting pieces,
- checkweighing (control +/-),
- dosing,
- percent setup,
- density determination of solids,
- density determination of liquids,
- animal weighing,
- statistics
- totalising
- peak hold
• functions related to setting a balance to ambient conditions at a
workstation
- enabling and disabling autozero system,
- setting parameter of measurement result averaging,
- value release,
- display backlight,
- beep signal,
• functions related to use of communication ports (RS232, USB, WIFI)
- setting communication port,
- setting bound rate,
- continuous data transmission in basic measuring unit,
- continuous data transmission in current measuring unit,
- automatic operation mode.
Balance can be used to weigh loads under the weighing platform – i.e. under hook
weighing option. Balance software enables generating a report from adjustment
process in a form of a printout containing modifiable data (see CAL REPORT)

7. START-UP
When plugged to mains, the balance displays name and number of software, and
afterwards proceeds to weighing mode.
7.1. Connecting peripheral devices
The balance must be unplugged from the mains before connecting or
disconnecting peripheral devices (printer or computer). Use only peripheral
devices recommended by the manufacturer with your balance. These have
been matched to your balance. After connecting a peripheral device, plug the
balance to mains.
7.2. Balance temperature stabilisation period
Before start of measuring processes, it is necessary to wait until the balance is
thermally stabilised.
For balances that were stored in much lower temperatures before plugging to
mains (e.g. during winter period) thermal stabilisation should last
approximately 4 hours for NPS balances, and 8 hours for NAS and NAPP
balances. During the thermal stabilization, the indications on the display panel
can change. Correct operation of a balance is possible within temperature
range specified in technical parameters, see point 1.
It is recommended that ambient temperature changes at balance’s place of
use are very small (slow to change).
