PRECAUTIONS
Prior to installation, use or maintenance activities, carefully read this user
manual and follow the provided guidelines.
Prior to the first use, carefully read this user manual. Use the weighing
device only as intended.
Place weighed loads in the centre of the weighing pan.
Load the weighing pan with loads of gross weight which does not exceed
the maximum capacity.
Mind not to leave heavy loads on the weighing pan for longer periods
of time.
Protect the indicator against considerable temperature variation, solar and
UV radiation, substances causing chemical reactions.
The weighing device must not be operated in hazardous areas
endangered with explosion of gases, and in dusty environments.
In case of damage, immediately unplug the device from the mains.
Scales to be decommissioned must be decommissioned in accordance
with valid legal regulations.
Do not let battery discharge in case of prolonged storage of the device
in low temperature.
Accumulators do not belong to regular household waste. The European
legislation requires discharged accumulators to be collected and disposed
separately from other communal waste with the aim of being recycled.
Symbols on batteries identify harmful compounds: Pb = lead,
Cd = cadmium, Hg = mercury. Dear user, you are obliged to dispose of the
worn out batteries as regulated.
If the scale is to be operated in conditions that are difficult due to
electrostatics (e.g. printing house, packing centre, etc.), you must connect
it to the earth wire. To enable this, the device features functional earthing
terminal, marked with symbol.

1.INTENDED USE
C315 series scales enable fast and accurate mass measurement in laboratory
and industry. They feature plastic housing and backlit LCD. The devices are
equipped with an internal battery which allows their operation in places where
there is no access to the mains. Standard C315 scales feature RS232 interface
for communication with external devices (printer, computer, etc.) and offers
wireless communication.
2.WARRANTY CONDITIONS
A. RADWAG feels obliged to repair or exchange all elements that appear
to be faulty by production or by construction.
B. Defining defects of unclear origin and means of their elimination can only
be realized with assistance of manufacturer and user representatives.
C. RADWAG does not bear any responsibility for damage or losses
resulting from unauthorized or inadequate performing of production
or service processes.
D. The warranty does not cover:
mechanical damage caused by product exploitation other than
intended, damage of thermal and chemical origin, damage caused by
lightning, overvoltage in the power network or other random event,
inappropriate cleaning habits.
E. Loss of warranty takes place if:
a repair is carried out outside RADWAG authorized service point,
service claims intrusion into mechanical or electronic construction by
unauthorized people,
the scale does not bear security stickers.
F. Warranty conditions outline the warranty period for rechargeable
batteries attached to the device for 12 months.
G. For detailed warranty conditions read the warranty certificate.
H. Contact with the central authorized service: [phone].
3.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.

6
3.1. 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.
3.2. 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.
4. SERVICE AND REPAIR
In case of any sign of damage, it is necessary to disconnect
the device form the mains immediately. The damaged
component must be replaced or repaired by RADWAG
service immediately.
In case of any problems with correct operation of the scale, contact the closest
manufacturer's service point.
In case of defects, deliver the faulty product to the manufacturer's service point.
If the product cannot be delivered to the manufacturer's service point, call the
service and report the defect. Repair scope and method will be set up.
The user is NOT ALLOWED to carry out any kind of repair
of the device himself/herself. Any attempt of scale
modification, repair etc., by unauthorized persons, will result
with loss of validity of manufacturer-issued certificates,
declarations and warranty.

5. RECYCLING
C315 scales must be recycled, they are not to be treated as a regular
household waste. Scales to be decommissioned must be decommissioned in
accordance with valid legal regulations.
6. MECHANICAL DESIGN
6.1. 1-Load-Cell Scales
1-load-cell scale C315 is intended to carry out fast and precise mass
measurement of up to 300 kg loads. Its characteristic feature is a platform with
one load cell only. The platform is equipped with a stainless steel weighing
pan. Depending on a scale model, the cross and base are made of either
stainless steel or powder-coated steel.

7.2. Levelling
7.2.1. Levelling: 1-Load-Cell Platform Scales
To level the weighing instrument turn its feet. Keep turning the feet until the air
bubble takes central position:
7.2.2. Levelling: 4-Load-Cell Platform Scales
To level the platform use the levelling feet and the level indicator. Each foot can
be turned left and right, turning causes tilt. Adjustment span of the scale level is
narrow therefore the correct level is obtained using steel washers which are to
be put under the feet.
Keep turning the feet until the air bubble takes central position:

7.3. Start-Up
The weighing device can be connected to the mains only with a power supply
that comes standard with the particular model. 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
button.

specified by PN-EN 45501 standard,
point 3.6.2).
Do not apply concentrated force (total
load in one point).
Avoid side loading, in particular side
shocks.
