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B. Devices that are to be withdrawn from usage should be sent back to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
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 3 to 4Ah charged
while connected to mains without stopping operation.
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.
In case of an elongated storage period in low
temperatures, it is not allowed the full discharge
Notice:
Some symbols on accumulators identify harmful elements/compounds:
Pb = lead,
Cd = cadmium,
Hg = mercury.
of the accompanied batteries.
A worn out accumulator can be exchanged to a new one
by the authorized service of the manufacturer.
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.
- 6 -
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
.
2.4. Scale washing
Weighing platforms are made of stainless steel (according to standards
PN–0H18N9, EN-1.4301, AISI–304) and silicon elements.
There is an exception, zinc coated overhead scales and painted livestock
scales made of mild constructional steel with aluminium cover plate on
the platform, polyester overlays and stainless steel or polyamide glands.
Caution:
Washing and disinfection agents should be matched to the scale.
Platforms of ramp and livestock scales as well as load-bearing structures
and weighing tracks of overhead scales can be washed with jet of water
(temp. up to +80°C) with an appropriate washing agent. Washing
measuring indicators/weighing terminals with the jet of hot water
is not allowed.
Caution:
It is advisable to cover measuring indicators/weighing terminals
while washing their surrounding with the jet of water.
- 7 -
To wash waterproof platform scales and indicators/terminals neither jet
of water nor hot water shall be used, in order not to damage the silicon
gaiter that covers the load cell inside the platform and the overlay or
glands in the indicator/terminal. To wash pans of platform scales they
should be taken off first. Then they can be washed ether with the jet
of water or by immersion.

5. ASSEMBLY AND LEVELLING
5.1. Assembly of scales A. Overhead scales
• Overhead scales are built of bearing elements and load cells as
measuring transducers. Scales are installed on a rail of a load
-bearing structure. The load cell is installed in the separated
section of the track.
• Overhead scales can be installed only by authorized services of
RADWAG. Otherwise the validity of warranty is automatically lost.
Do not introduce any mechanical stresses to the weighing system
during installation.
• It is forbidden to use any chemical agents comprising penetrators
for washing.
• The scale should be periodically cleaned from lubricants and
impurities (especially the connection between the scale rail
and the crane track).
B. Livestock scales
• Remove the transport protection if installed.
• Screw in levelling feet to mandrels placed in load cells
• Put the scale in the spot of usage on a flat stable ground.
- 13 -
C. Ramp scales
• Before setting the scale mount the steel camping ring (2) to the basis
of feet (1) using expanding ring (3) and then screw in the basis of the
foot (1) in the mandrel (4).
• Put the scale on the flat ground. Put ramps on steel clamping. Take
off ramps and mark (through the holes in clamping) places for drilling
holes for anchors. After drilling mount clamping to the ground.

8 - anchor
- 14 -
D. Waterproof platform scales
Unpack and put the scale on a flat even stable surface far away
from sources of heat and then:
• Unscrew the pillar and the transport handler from the platform:
• Turn the pillar and mount it to the platform. The surplus cable
place inside the pillar:
• Pick up the pan and remove the transport protection:
- 15 -
5.2. Levelling the scale A. Platform scales
After unpacking the scale should be levelled out. Use levelling legs
and the level condition indicator installed in the basis of the scale.
B. Four load cell scales
Level scale by means of turning levelling feet and external level
indicator. Put the pads under the regulation legs and observe the
level condition indicator. The instrument is levelled correctly if the
air bubble do not move more than 2mm from the central position.
Each leg can be screwed in and out in order to level the scale.
Correct levelling can be done by putting steel pads under the legs.
6. GETTING STARTED
After unpacking and mounting (chapter 5 of this manual):
• Turn the device on using the
the key for about 0.5 sec,
• Wait for the test completion,
key – keep pressing
- 16 -
• Then you will see zero indication and pictograms:
- zero indication

11. WEIGHING
Put a load you want to weigh on the weighing pan. When the
pictogram appears it means that the result is stable and ready to read.
In order to assure long-term operation and appropriate measurements of
weighted loads following precautions should be taken into consideration:
• Loads should be placed on the pan delicately and carefully
in order to avoid mechanical shocks:
• Loads should be placed centrally on the pan (errors caused by
eccentric weighing are outlined by standard PN-EN 45501
ch. 3.5 and 3.6.2):
• Do not load the pan with concentrated force:
• Avoid side loads, particularly side shocks should be avoided
- 21 -
Special line scales should be loaded with intended loads:
• For ramp scales (hand trucks used in meat industry) the platform
should be matched to the trucks with maximum weight and the
wheels were close to the load-bearing sections:
• For livestock scales – swine, cattle:
− platforms with low railing for swine,
− platforms with high railing reinforced connecting links
at the top edge.
• For overhead scales (goods hung on hooks) adapted
to underslung tracks:
− Hooks appropriate for the track and scale,
− Smooth travelling along the load cell without jerks
and movements aside,
− Tensometer (load cell) loaded uniformly.
- 22 -
11.1. Tarring
In order to determine the net mass put the packaging on the pan.
After stabilising press -
(Net pictogram will be displayed in the left
upper corner and zero will be indicated).
After placing a load on the weight pan net mass will be shown.
Tarring is possible within the whole range of the scale. After unloading
the pan the display shows the tarred value with minus sign.
Notice:
Tarring cannot be performer when a negative or zero value is being
displayed. In such case <Err3> appears on the display and short
audible signal will be emitted.
11.2. Inscribing tare value
You can also inscribe a tare value. While in weighings mode press:
• Press simultaneously and ,
• You will see :
- 23 -
• Using and set the tare value,
• Press
,
• Program returns to weighings mode. The inscribed tare
value can be seen on the display with „–” sign,
• Tare can be inscribed anytime in weighings mode.
Notice:
1. You cannot inscribe a new tare value when the tare value in memory
is greater than zero. In the case of trying this the <Err3> message
will be displayed and short audible signal will be emitted.
2. Users can also enter up to 9 tare values to the scale memory
(see 15.10 of his manual).
11.3. Zeroing
To ZERO the scale press: .
The scale will display zero and following pictograms:
and .
Zeroing is only possible within the scope of ±2% of full scale. While
zeroing outside the scope of ±2% you will see <Err2>. Zeroing is
possible only in stable state.
Notice:
Zeroing is possible only within the ±2% interval of the maximal range.
If zeroing is performed beyond this range the <Err2> message and
short audible signal will be emitted.
11.4. Weighings in two ranges
Switching between the I range and the II range happens automatically
(exceeding Max of the I range). Weighings in the second range is
signalled by a pictogram in the top left corner of the display.
Then weighings is done with the accuracy of the II range to the moment
of returning to zero (autozero range
) where the scale switches back
to the I range.
