• Unpack the device and place it on a flat and even surface. Keep it far
away from any sources of heat.
• Install the weighing pan, follow the below figures:
WLC/A1 precision scale WLC/A2 precision scale
5.1. Under-Pan Weighing
The WLC/A1, WLC/A2 scales enable weighing loads below scale (so called
under-pan weighing). This is an alternative for loads of non-standard
dimensions and shapes, and for loads generating magnetic field.
Preparing the scale for the under-pan weighing:
1. Unpack the scale, assembly it
following section 5 of this user
manual.
-
2. Put the scale right side down.
Page 10
10
3. Remove the hole plug.
4. Mount the hook and put the
scale bottom side down.
6. START-UP AND OPERATION
6.1. Levelling
To level the weighing instrument turn its feet. Keep turning the feet until the air
bubble takes central position:
6.2. Connecting the Scale to the Mains
The weighing device can be connected to the mains only with a power supply
that comes standard with the particular model.
Page 11
11
Nominal voltage of the power supply (specified on the power supply data plate)
has to be compatible with the mains nominal voltage.
Procedure:
• Connect the power supply to the mains. Plug it to the power supply socket
(back side of the scale housing).
• Press
key. The key is also used to switch the scale on/off.
• Display test proceeds (all symbols are backlit for a moment), program
name and number is displayed first, ZERO indication with reading unit
next (displayed reading unit is conditioned by scale type).
• In case the weighing result is not zero after indication stabilisation, press
key.
6.3. Warm-Up Time
• For correct scale operation, the workroom temperature must range
between +15°C ÷ +30°C.
• It takes 30 minutes for the device to warm up.
• During the thermal stabilization, the indications on the screen can change.
• If you want to carry out adjustment operation, make sure that your device
is thermally stable.
• Temperature and humidity variations during operation may cause
indication errors. To remove the indication errors perform user adjustment.
6.4. Battery Charge Status
The scale of standard design is equipped with an internal battery. Battery state
is signalled by
pictogram, the pictogram is displayed in the top bar of the
display.

6.5. Battery Charge Status Check
• Press and keys combination.
• Battery charge state, given in %, is displayed for 2 s.
• Next, home screen is displayed automatically.
7. MAINTENANCE ACTIVITIES
In order to ensure safety in the course of cleaning, it is necessary to disconnect
the device from the mains. With this condition met, uninstall the weighing pan
and other detachable components.
Cleaning the weighing pan while still installed may cause
damage of the measuring system.
7.1. Cleaning ABS Components
To clean dry surfaces and avoid smudging, use clean non-colouring cloths
made of cellulose or cotton. You can use a solution of water and detergent
(soap, dishwashing detergent, glass cleaner). Gently rub the cleaned surface
and let it dry. Repeat cleaning process if needed.
In the case of hard to remove contamination, e.g. residues of adhesive, rubber,
resin, polyurethane foam etc., you can use a special cleaning agents based on
a mixture of aliphatic hydrocarbons that do not dissolve plastics. Before using
the cleanser for all surfaces we recommend carrying out tests. Do not use
cleansers containing abrasive substances.
7.2. Cleaning Glass Components
Select dissolvent depending on a dirt. Never soak the glass panes in alkaline
solutions since they interact with glass and may cause damage. Do not use
cleansers containing abrasive substances.
For organic dirt use acetone first, next use water or detergent. For other than
organic dirt use diluted acid solutions (soluble salts of hydrochloric or nitric
acid) or base solutions (ammonium or sodium base). To remove ACIDS use
protophilic solvent (sodium carbonate), to remove BASE use protogenic solvent
(mineral acid of various concentration).
In case of heavy contamination use brush and detergent, nevertheless avoid
detergents containing large and hard molecules which could potentially scratch
glass panes.
Page 13
13
At the end of the cleaning process rinse the pane using distilled water. Use soft
brush with wooden or plastic handle exclusively in order to avoid risk
of scratches. Do not use wire brush. Rinsing is a necessary cleaning process
stage allowing to remove remaining soap, detergents and other cleansers from
the panes prior their reinstallation. After preliminary cleaning process stage,
rinse the pane using running water first, distilled next.
Avoid drying the panes either using paper towel or forced air circulation since
some fibres, grains or contamination of other type could permeate into the
panes thus causing weighing errors. We do not recommend using driers when
drying measuring glass tools. It is a frequent treatment to leave glass
components on a rack to dry.
7.3. Cleaning Stainless Steel Components
Avoid using cleansers containing any corrosive chemicals, e.g. bleach
(including chlorine). Do not use cleansers containing abrasive substances.
Always remove the dirt using microfiber cloth to avoid damage of protective
coating.
In case of a daily maintenance:
1. Remove the dirt using cloth dipped in warm water.
2. For best results, add a little bit of dishwashing detergent.
7.4. Cleaning Powder-Coated Components
For preliminary cleaning process stage you need running water or wet sponge
featuring large holes, this will help you to remove loose, heavy dirt. Do not use
cleansers containing abrasive substances.
Next, using cloth and cleanser-water solution (soap, dishwashing liquid) gently
rub the cleaned surface.
Avoid using cleanser without water since it may result with damage of the
cleaned surface, please mind that large amount of water mixed with cleanser
is a must.
7.5. Cleaning Aluminium Components
While cleaning aluminium components use products acid by nature, e.g. spirit
vinegar, lemon. Do not use cleansers containing abrasive substances. Avoid
using hard brush, this may cause scratches. It is recommended to use
microfibre cloth.
While polishing the surface use circular movements. Use clean, dry cloth
to make the surface shine.

12. ADJUSTMENT
In order to ensure the highest weighing accuracy, it is recommended
to periodically introduce corrective factor of indications to scale memory,
the said factor must be referred to a reference weight. This is so called
adjustment. Adjustment has to be carried out:
• prior weighing,
• if long breaks between successive measuring series occur,
• if the ambient temperature has changed dynamically,
• if the scale has been relocated.
Page 21
21
Adjustment types:
• external adjustment performed using an external weight of declared mass,
i.e. mass that cannot be modified,
• user adjustment performed using an external weight of mass of any value
comprised within the weighing range, however not lower than 30% of the
maximum capacity value.
• automatic internal adjustment,
• manual internal adjustment.
In case of verified scales only two adjustment types are
available: automatic internal adjustment and manual internal
adjustment. Remember to carry out the adjustment process
when there is no load on the pan! When the weighing pan
is loaded with too heavy load, message <Err4> is displayed.
In such case, unload the weighing pan and repeat the
adjustment. Adjustment process can be aborted if necessary
at any time, to do it press
key.
