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B. Devices that are to be withdrawn from usage should be sent back to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 3 to 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.

- 6 -

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 non­rechargible 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.

- 7 -

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:

• 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

.

- 17 -

5.3. Waterproof scales of WPT/H, WPT/HR series

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:

- 18 -

• 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.

6. GETTING STARTED

• After unpacking and mounting the scale level it out.

Use levelling legs and the level condition

indicator installed in the basis of the scale.

• Turn the device on using the

key – keep pressing the key

for about 0.5 sec,

• Wait for the test completion,

• Then you will see zero indication and pictograms:

- zero indication

- stable result

kg - weight unit

• If the indication is not zero press zero key.

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:

- 24 -

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 :

- 25 -

• 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.
