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B. Devices that are to be withdrawn from usage should be sent back to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

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:

- 7 -

• 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.

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:

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.

• 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.

12.2. 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 - 10.2.2.

- 30 -

12.3. Autozero function

The autozero function has been implemented in order to assure precise
indications. This function controls and corrects „0” indication. While the
function is active it compares the results continuously with constant
frequency. If two sequentional results differ less than the declared
value of autozero range, so the scale will be automatically zeroed
and the pictograms

and will be displayed.

When AUTOZERO is disabled zero is not corrected automatically.
However, in particular cases, this function can disrupt the measurement
process e.g. slow pouring of liquid or powder on the weighing pan. In
this case, it is advisable to disable the autozero function.

Procedure:
