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B.Devices that are to be withdrawn from usage should be sent back to the producer or in case of own utilization do it according to the law.
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.
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.
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.
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 .

C.RADWAG does not take any responsibility connected with destructions or losses derives from non-authorized or inappropriate (not adequate to manuals) production or service procedures,
D.Warranty does not cover:
•Mechanical failures caused by inappropriate maintenance of the device or failures of thermal or chemical origin or caused by atmospheric discharge, overvoltage in mains or other random event,
•Inappropriate cleaning.
E.Loss of warranty appears after:
•Access by an unauthorized service,
•Intrusion into mechanical or electronic construction of unauthorized people,
•Removing or destroying protection stickers.
F.Warranty conditions outline the warranty period for rechargeable batteries attached to the device for 12 months.

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 -
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.
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).
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.
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.
