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, 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.
A worn out battery can be replaced only by the manufacturer or by the
authorized service.
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 H315 weighing indicator is intended to be a part of construction
of industrial scales based on load cells. It is equipped with a stainless steel
housing of high IP. Clear weighing result presentation is ensured due to a large
display (LCD).
Standard indicator features one RS232 interface and USB connector
for connection with peripheral devices (printer, computer, etc.). The indicator
can be optionally equipped with an internal battery, this allows its operation
in places where there is no access to the mains.
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 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.
3.2. 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.

8.3. Device Defining
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
for balance/scale type selection.
Select balance/scale type, do it using operation panel (refer to factory
parameters table, section 8.2 of this manual).
Press key to confirm, weighing range window is displayed.
Select appropriate weighing range, do it using the operation panel.
Press key to confirm, <0.1.1duu> submenu is displayed.
Exit to home screen, to do it press key repeatedly.

18
While defining balance/scale type, additional parameters are
set automatically. These are among many battery type,
internal adjustment accessibility, additional modules and
communication interfaces accessibility.
8.4. Factory Adjustment
8.4.1. External Adjustment Process
Enter factory setup submenu: <P.0.FAct / 0.3.CAL>.
Enter <0.3.1.CLE> function, text <UnLoAd> is displayed.
Unload the weighing pan.
Press key, adjustment zero point gets determined.
With adjustment zero point determined, first text <LoAd>, next mass of an
adjustment weight that is to be loaded onto the weighing pan is displayed.
Load the weighing pan with the required adjustment weight.
Press key, adjustment starts.
After adjustment completion, <0.3.1.CLE> submenu is displayed
automatically.
Exit to the home screen, to do it press key repeatedly.
8.4.2. Start Mass Determination
Enter factory setup submenu: <P.0.FAct / 0.3.CAL>.
Enter <0.3.2.Std> function, text <UnLoAd> is displayed.
Unload the weighing pan.
Press key, start mass determination starts.
Upon completed determination process, <0.3.2.Std> submenu is
displayed.
Exit to the home screen, to do it press key repeatedly.
If start mass determination or adjustment factor
determination takes more than 360 seconds then <Err8>
error is displayed and short sound signal is heard. In such
a case the scale requires readjustment/recalibration,
perform it providing as stable ambient conditions as
possible!

19
8.4.3. Correction of Start Mass Expressed in Converter's Divisions
Enter factory setup submenu: <P.0.FAct / 0.3.CAL>.
Enter <0.3.4.Stu> submenu, value of start mass expressed in converter's
divisions is displayed.
Correct the value, to do it use operation panel, next press key to
confirm changes.
Exit to the home screen, to do it press key repeatedly.
8.5. Linearity Correction
Prior to linearity correction it is necessary to determine real scale
characteristics. Correction mechanism allows to enter corrections in 20 points
maximum.
8.5.1. Entering Linearity Correction Points
Enter factory setup submenu: <P.0.FAct / 0.4.Line / 0.4.1.dSG>, text
<Cont?> is displayed.
Press key to confirm. Text <Pnt1> is displayed (linearity connection
point no. 1).
Press key, window for entering mass value for linearity correction
point no. 1 is displayed.
Enter the given value, next press key to confirm, text <Pnt2>
is displayed (linearity connection point no. 2).
Press key, the program automatically suggests value for the next
linearity correction point.
Press key to confirm the suggested value, or enter a new value
(do it using the operation panel).
Keep repeating this procedure until you enter value close to maximum
capacity value.
While attempting to enter correction point value greater than
maximum capacity value, <Err Hi> error is signalled.
