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B. Devices that are to be withdrawn from usage should be sent back to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.
•Weighing indicators 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.
•PUE C/31H and PUE C/31H/Z weighing indicators (stainless steel
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.

- 7 -
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 .

10. 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.
10.1. 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.
10.2. Inscribing tare value
You can also inscribe a tare value. While in weighings mode press:
•Press simultaneously and ,
•You will see :

- 16 -
•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 14.10 of his manual).
10.3. 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.

- 17 -
10.4. 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.
10.5. 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:

- 18 -
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,
•After you select the unit press , the scale returns to:
•Return to weighing according to chapter - 9.2.2.
Notice:
After turning on the scale always sets the basic unit.
10.6. 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:

- 19 -
•After you select the unit you want come back to weighing procedure.
Options:
A. When [kg] is a basic unit, users can select following units:
[kg, lb, N], [lb] is not accessible for verified scales.
B. When [g] is a basic unit, users can select following units:
[g, ct, lb], [lb] is not accessible for verified scales.
11. MAIN PARAMETERS
Users can adjust the scale to external ambient conditions (filtering level)
or particular needs (autozero operation, tare memory). This parameters
are placed in <P1.rEAd> submenu.
11.1. Setting a filtering level
Procedure:
•Enter the submenu <P1.rEAd> and then:
1 - 4 - level of filtering
•By pressing select the filtering level you need.

- 20 -
Notice:
Filtering level influences the time of stabilization. The higher the filtering
level is the longer stabilization time is needed.
Return to weighing:
See - 9.2.2.
11.2. Median filter
This filter eliminates short changes (impulses) of measure signal
(e.g. shocks).
Procedure:
•Enter the submenu <P1.rEAd> and then:
Fnnd no - filter disabled
Fnnd YES - filter enabled
Return to weighing:
See - 9.2.2.
