1. INTENDED USE
Scales are designed for fast and precise measurements of weighed loads
masses and direct commercial settlements. Tarring in full weighing range
enables to determine net mass of weighed loads.
Functions:
•backlight of display
•level of filtration
•autozero function
•setting baud rate of transmission
•continuous data transmission for RS 232
•automatic operation for RS 232
•designed printouts
•designation minimum mass for function operating
•counting pieces
•+/- mass control
•percentage deviation from standard mass
•latch of maximum scale indication
•automatic tare
•memory of tare
•Memory of 9 tare values
•inscribing tare value
•automatic scale switch-off
•user calibration
•Totalizing
•Weighing animals
User functions may have attribute of accessibility. For this reason it is
possible to adjust scale to individual needs to provide access to only
these functions which are currently needed. Attribute determination
accessible / inaccessible is possible in user menu and described in
further part of manual.

2. PRECAUTIONS
2.1. Maintenance
A. Please, read carefully this user manual before and use the device
according to its intended use.
B. Devices that are to be withdrawn from usage should be sent back to
the producer or in case of own utilization do it according to the law.
2.2. Accumulator / battery pack
The device connected to mains inteligently monitors the battery state and
charges it if possible. After sudden lack of power supply from the mains
the device automatically switches to accumulator without breaking
operation.
•Scales aquipped with indicator PUE C/31 (plastic casing) are devices
designed to be supplied from NiMH batteries (nickel-metal-hydrogen)
with rated voltage of 1.2V, size R6 and capacities from 1800 to
2800mAh charged while connected to mains without stopping
operation.
•Scales equipped with PUE C/31H and PUE C/31H/Z weighing
indicators (stainless steal housing) are devices designed to be
supplied from SLA accumulators (Sealed lead acid type) 6V o
and capacity 3to 4Ah charged while connected to mains without
stopping operation.
In case of an elongated storage period in low
temperatures, it is not allowed the full discharge
of the accompanied batteries.
The equipment including accumulators does not belong
to your regular household waste. The European legislation
requires that electric and electronic equipment be collected
and disposed separately from other communal waste with
the aim of being recycled.

Notice:
Some symbols on accumulators identify harmful elements/compounds:
Pb = lead,
Cd = cadmium,
Hg = mercury.
2.2.1. Power supply of weighing indicators in plastic casings
Indicators in plastic casing are intended to be supplied from a power
adapter or from NiMH rechargeable battery pack (standard equipment).
New rechargeable batteries should be formatted according to the
description in the chapter 14.4.4. of this manual.
Alternatively, you can use to power the device R6 size standard non-
rechargible batteries. If you want to use normal batteries instead of
rechargeable ones, proceed as follows:
•Before installing non-rechargeable batteries turn on the device
and set <5.5.CHr6> to <no>, to switch off charging.
•Then install the batteries.
Installing batteries without changing <5.5.CHr6> to <no>
may cause damage of batteries and the indicator.
2.2.2. Replacement of worn batteries
Users have the ability to replace worn out batteries to new ones in
weighing indicators PUE C/31 (plastic casing).
Procedure:
•Open the lid of the chamber for
batteries placed in the bottom of
the indicator casing:

- 8 -
•Remove discharged and then insert new batteries into the chamber,
according to given polarity (+/-):
•Close the lid of the chamber for batteries:
In PUE C/31H and PUE C/31H/Z weighing indicators
(stainless steel housing) the worn out accumulator can
be exchanged to a new one by the authorized service
of the manufacturer.
2.3. Operation in a strong electrostatic field
If the device is about to operate in a strong electrostatic field
(e.g. printing houses etc.) it should be connected to the earthing.
Connect it to the clamp terminal signed .

3. WARRANTY CONDITIONS
A. RADWAG is obliged to repair or change those elements that appears
to be faulty because of production and construction reason,
B. Defining defects of unclear origin and outlining methods of
elimination can be settled only in participation of a user and
the manufacturer representatives,
C. RADWAG does not take any responsibility connected with
destructions or losses derives from non-authorized or inappropriate
(not adequate to manuals) production or service procedures,
D. Warranty does not cover:
•Mechanical failures caused by inappropriate maintenance of
the device or failures of thermal or chemical origin or caused
by atmospheric discharge, overvoltage in mains or other
random event,
•Inappropriate cleaning.
E. Loss of warranty appears after:
•Access by an unauthorized service,
•Intrusion into mechanical or electronic construction
of unauthorized people,
•Removing or destroying protection stickers.
F. Warranty conditions outline the warranty period for rechargeable
batteries attached to the device for 12 months.
G. The detailed warranty conditions one can find in warranty certificate.
H. Contact with the central authorized service:
