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 device only
as intended.
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, andin 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.

1.INTENDED USE
PUE C315 weighing indicator is a device intended to make industrial scales
operating on the basis of load cells. The indicator is equipped with an internal
battery, this allows its operation in places where there is no access to the
mains. Clear weighing result presentation is ensured due to large display
(LCD). Indicator's housing is made of plastic. Standard indicator features
RS232 interface for cooperation with peripheral 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 device does not bear company protective 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.
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).

6
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.

5.INDICATOR INSTALLATION
5.1. Unpacking and Installation
A. Take the indicator out of the packaging.
B. Connect the indicator and the platform and place the set on a flat and
even surface. Keep it far away from any sources of heat.
C. To level the weighing instrument turn its feet. Keep turning the feet until
the air bubble takes central position:
5.2. Start-Up

8.3. Defining the device
Defining the device at the production stage requires entering basic
balance/scale parameters: serial number, weighing device type, weighing
range.
Procedure:
Enter factory setup <P0.FAct>.
Go to <0.1.Glob / 0.1.1.duu> submenu, text <Cont?> is displayed.
Press key, text <nr FAc> is displayed, next you see window
for entering the serial number.
Enter the serial number, do it using the operation panel.
Press key to confirm, text <type> is displayed, next you see window

<Cont?> is displayed.
Press key for confirmation.
Exit to home screen, to do it press key repeatedly.
8.6. Gravitational coefficient
The function of gravity correction compensates changes of gravity force being
a result of different latitude. It allows to carry out correct balance/scale
calibration away from the point of subsequent use. The gravity correction value
must be entered with reference to tables prepared by „Radwag Balances and
Scales” or calculated using the below formula:
