2. BASIC INFORMATION

2.1. Intended use

Precision balance APPC series is designed to determine the weighing value of
loads in laboratory environment. It is intended for application as a non­automatic weighing instrument only, i.e. the material to be weighed is manually
and carefully placed in the center of the weighing pan. Weighing result should
be read only after stable reading has been obtained – stability pictogram is
visible on balance’s display.

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 stabilization of the
measurement result. Do not place any magnetic materials on the weighing pan,
as this can cause damage of 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 endangered by an
explosion. 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 not valid at the following:

• Non-observation of the guidelines of this user manual,

• Use of balance other than specified in this manual,

• Alternation to or opening of the device,

• Mechanical damage and damage caused by media, natural water,

and tear,

• Inappropriate assembling or defects of electric installation,

• Overloading of the measuring instrument.

- 7 -

2.4. Monitoring metrological parameters of the instrument

Metrological characteristics of the balance requires periodical inspection
carried out by its operator. Inspection frequency is conditioned by ambient
conditions in which the balance is used, types of performed processes and
accepted quality management system in an organization.

2.5. Data included in this user manual

Please read the user manual carefully before assembling and startup, 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 I 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
dispatching the balance. Before packing, disconnect all attached cables and
remove any loose/movable parts (weighing pan, anti-draft shields, etc.). Please
place balance and its components in their original packaging, and protect them
against damage during transport.

- 8 -

4. UNPACKING, ASSEMBLING AND STARTUP

4.1. Assembling and place of use

• 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

o

C ÷ +40oC,

• 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 safety measures 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 influence of static electricity on the measurement process,
ground the balance’s housing. the grounding bolt is located at the back of
balance’s housing.

4.2. Unpacking

Cut protective tape. Carefully remove the balance from its packaging. Remove
any accessories from their packaging needed to correct balance operation.

- 9 -

• Remove the weighing pan from balance’s housing and remove the
transport protections, as shown on above figure.

• After unpacking, unscrew bolt (1) locking balance’s adjustment
mechanism.

• Assembly the weighing pan.

• Pay attention to correct positioning of the weighing pan on balance’s

mandrels – the weighing pan must not touch balance’s housing, and it
should rest steadily.

• After removing transport protections, and assembling the weighing pan
connect the terminal to balance’s socket located at the back of the housing
– only non legalization balaces, and next connect needed peripheral
equipment. Only then plug the balance to mains (power socket is located
at the back of balance’s housing).

• Place the balance in its intended place of use.

- 10 -

• Level the balance by turning its adjustable feet. Then using a wrench (3)
tighten up the nut (2) on the adjustable foot (1) to balance’s basis until
refusal point.

Setting

Before plugging to mains, level the balance using adjustable
feet. Turn the feet in a way that the air bubble of the level is
located centrally.

• Only then plug the balance to mains (power socket is located at the back
of balance’s housing).

4.3. Standard delivery components

• Balance.

• Weighing pan.

• Power adapter.

• User manual.

4.4. Cleaning

Balance should be cleaned with damp cloth by gentle wiping the smudges of
dirt. In order to clean the weighing pan of the balance, please remove it from
the weighing chamber. Cleaning of the pan when assembled may cause

damage of the measuring system of the balance.

4.5. Plugging to mains

Balance can be plugged 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’s housing. Balance display will light and show
name and number of software, after which balance will display 0.00g (in case
of balances with readability 0,01g) or 0.0g (for balances with readability 0,1g). .
If indication is other than zero, press ZERO/TARE key.

- 11 -

4.6. Connecting peripheral equipment

The balance must be unplugged from the mains before connecting or
disconnecting any peripheral equipment (printer, PC computer). Use only
peripheral equipment recommended by the manufacturer with your balance.
These have been ideally coordinated to your balance. On connecting a
peripheral device, plug the balance to mains.

7. START-UP

When plugged to mains, the balance displays name and number of software, and
afterwards proceeds to weighing mode.

Balance temperature stabilization period.

Before start of measuring processes, it is necessary to wait until the balance is
thermally stabilized. It is a period of so called balance self-heating. In case of
balances APP series self-heating period takes approximately 15 minutes. The
specified time interval refers to balances that have been stored in room temperature
before plugging to mains.
For balances that were stored in much lower temperatures before plugging to mains
(e.g. during winter period) thermal stabilization should last approximately 4 hours.
Correct operation of a balance is possible within temperature range specified in the
technical parameters, see point 1. If the balance is placed in area which ambient
temperature is out of temperature range specified in the technical data, then
balance’s display may signal such situation by lighting an appropriate marker (a
black triangle).

In case the balance displays the marker, increase or decrease ambient
temperature, depending on present temperature value. It is recommended that
ambient temperature changes at balance’s place of use are very small (slow).
