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
- inscribing tare value
- Memory of 9 tare values
- 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B. Devices that are to be withdrawn from use age should be sent back
to the producer or in case of own utilization do it according to the law.

2.2. Accumulator / battery pack WTB scales 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.
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
Notice: Some symbols on accumulators identify harmful elements/compounds: Pb = lead, Cd = cadmium, Hg = mercury.
of the accompanied batteries.
A worn out accumulator can be exchanged to a new one by the authorized service of the manufacturer.
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. 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.

7. BALANCE LEVELLING

Operation temperature range for this device is outlined as +15°C ÷ +30°C;
After powering up this device requires 30 minute worming up;
During the worm-up time the indication can change;
User calibration should be performed after the warm-up time.
Temperature and humidity changes during operation can increase
measurement errors, which can be minimized by performing the user calibration process.

12. 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
- 15 -

12.1. 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.

12.2. 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 16.10 of his manual).

12.3. 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.

12.4. 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.
- 17 -

12.5. 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,
- 18 -
After you select the unit press , the scale returns to:
Return to weighing according to chapter - 11.2.2.
Notice:
After turning on the scale always sets the basic unit.

12.6. 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.
- 19 -
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.

13. 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.

13.1. 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 - 11.2.2.

13.2. 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 - 11.2.2.
