1. INTENDED USE
Platform 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.
Additional display is additional equipment of scale. It is to control
mass of weighed load by another person.
Functions:
•backlight of display
•level of filtration
•median filter
•autozero function
•setting baud rate of transmission
•designation minimum mass for function operating
•automatic tare
•memory of tare
•inscribing tare value
•automatic scale switch-off
•user calibration
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B. Devices that are to be withdrawn from usage should be sent back to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 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.

- 6 -
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
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.

- 7 -
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:

- 8 -
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 .

5.1. Scales of WPT/P 2 series
Unpack and put the scale on a flat even stable surface far away from
sources of heat and then:
•Remove transport protection:
•Set the pillar with additional
display vertically:
•Screw down the pillar to the scale basis:
•Turn the display head:

- 11 -
5.2. Scales of WPT/P 60 series
Unpack and put the scale on a flat even stable surface far away from
sources of heat and then:
A. Remove transport protection:
B. To attach the pillar to the scale body:
•Screw down the pillar handler to the platform:
•Stretch delicately the cable so it did not touch the ground after
mounting:

- 12 -
•The surplus cable wind and place inside the
pillar as show below:
Put the indicator with the hendler on the
pillar and tighten up the handwheels:
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,

- 13 -
•Then you will see zero indication and pictograms:
- zero indication
- stable result
kg - weight unit
•If the indication is not zero press 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

- 17 -
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 :

- 18 -
•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:
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.
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.

- 19 -
11.5. Selection of basic weight unit
This function is used to set weight unit the scale will start with.
Procedure:
•Enter the submenu <P3.Unit> and then:
•press ,until the expected unit appears on the display:
Options:
A. When the basic unit is [kg], users can toggle between:
[kg, lb, N],for verified scales [lb] is not accessible,
B. If the basic unit is [g], users can toggle between:
[g, ct, lb], for verified scales [lb] is not accessible,

- 20 -
•After you select the unit press , the scale returns to:
•Return to weighing according to chapter - 10.2.2.
Notice:
After turning on the scale always sets the basic unit.
11.6. Temporarily selected unit
This function is used to set weight unit the scale will use temporarily
until the next power off or next selection.
Procedure:
•Press and then:
•After you select the unit you want come back to weighing procedure.
