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Devices that are to be withdrawn from use age should be sentback to the producer or in case
of own utilization do it accordance to the law.
2.2.
Accumulator / batterypack
The device connected to mains power 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.
•
VWR scales are devices designed to be supplied from SLA accumulators (Sealed lead acid
type) 6V and capacity3 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
6
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.
Caution:
Some symbols on accumulators identify harmful elements/compounds: Pb = lead,
Cd = cadmium, Hg = mercury.
2.3.
Operation in a strong electrostaticfield
If the device is about to be operated in a strong electrostatic field (e.g. printing houses etc.) it
should be grounded.
Connect it to the clamp terminal signed .
2.4.
Maintenanceactivities
It is necessary to uninstall the weighing pan and other detachable components prior to
cleaning the balance, this guarantees safety.
Cleaning ABS components
To clean dry surfaces and avoid smudging, use clean non-coloring cloths made of cellulose or cotton.
You can use a solution of water and detergent (soap, dishwashing detergent, glass cleaner). Gently
rub the cleaned surface and let it dry. Repeat cleaning process if needed.
In the case of contamination which is hard to remove, e.g. adhesive, rubber, resin, polyurethane foam
residues etc., you can use a special cleaning agents based on a mixture of aliphatic hydrocarbons
that do not dissolve plastics. Before using the cleanser for all surfaces, we recommend carrying out
tests. Do not use products containing abrasive substances.
Cleaning stainless steel components
Avoid using cleansers containing any corrosive chemicals, e.g. bleach (containing chlorine). Do not
use abrasive substances. Always remove the dirt using microfiber cloth to avoid damage of protective
coating.
In case of a daily maintenance:
1.
Remove the dirt using cloth dipped in warm water.
2.
For best results, add a little dishwashing detergent.
Cleaning powder-coated components
For the preliminary cleaning stage, you need a wet sponge featuring large holes, this will help
you to remove loose, heavy dirt.
Do not use cleansers containing abrasive substances.
7
Next using cloth and cleanser-water solution (soap, dishwashing liquid) gently rub the cleaned
surface.
Avoid using cleanser without water since it may result in damage of the cleaned surface, please
note that large amount of water mixed with cleanser is a must.
Cleaning aluminium components
While cleaning aluminium components, use products acidic in nature,
e.g.
spirit vinegar, lemon. Do not use abrasive substances. Avoidusing a hard brush, this may cause
scratches. It is recommended to use a microfiber cloth.
While polishing the surface use circular movements. Use clean, dry cloth.

UNPACKING ANDASSEMBLY
•
Unpack and put the scale on a flat even stable surface far away from sources ofheat,
•
Install the weight pan according to the drawings below:
6.
UNDER-PANWEIGHING
The scale offers under-pan weighing option wherein the load is weighed when hanged under the
device. This is especially useful when there is a need to weigh a load of non-standard dimension,
shape, or load that generates an electromagnetic field.
Preparing the scale for under-pan weighing:
1. Unpack the scale, assemble it,
then turn the scale one side down.
10
2. Remove the hole
plug.
3. Fix the hook.
4. Turn the scale bottom side down.
11
7.
GETTING STARTED
•
After unpacking and mounting the scale, level the scale. Adjust the leveling feet until the
leveling bubble reaches the correct location.
•
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 indicationand pictograms: - zeroindication
- stable result
kg - weightunit
•
If the indication is not zero press key.
8.
BALANCELEVELING
•
Operation temperature range for this device is outlined as
+15C +30C;
•
After powering up this device requires 30 minute warming up
•
During the warm-uptime the indication can change
•
User calibration should be performed after the warm-uptime.
•
Temperature and humidity changes during operation can increase measurement errors, which
can be minimized by performing theuser calibrationprocess.

Return to the weighingmode
The changes that have been introduced should be saved in order to keep them in the
memory for good.
While leaving parameters press key until thetext <SAuE?> appears on the
display. Then press:
–to save changesor
–to leave without changes.

WEIGHING
Place 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, the following precautions should be taken into consideration:
•
Loads should be placed on the pan delicatelyand carefully in order to avoid mechanical
shocks:
•
Loads should be placed centrally on the pan (errorscaused
by eccentric weighing are outlined by standard PN-EN 45501 ch. 3.5 and 3.6.2):
16
•
Do not load the pan with concentrated force:
•
Avoid side loads, particularlyside shocks should be avoided
13.1.
Taring
In order to determine the net mass put the packaging on the pan. After stabilizing 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.
Taring is possible within the whole range of the scale. After unloading the pan the display
shows the tarred value with minus sign.
Notice:
Taring 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.
17
13.2.
Inscribing tarevalue
You can also inscribe a tare value. While in weighing’s mode press:
•
Press simultaneously
and
,
•
You will see:
•
Using and set the tarevalue,
•
Press ,
•
Program returns to weighing’s mode. The inscribed tare value can be seen on the display
with "–" sign,
•
Tare can be inscribed anytime in weighing’s 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 willbe displayed and short audible signal will be emitted.
2.
Users can also enter up to 9 tare values to the scale memory.
13.3.
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.
18
13.4.
Selection of basic weightunit
This function is used to set weight unit the scale will start with.
Procedure:
•
Enter the submenu <P3.Unit> andthen:
•
press , until the expected unit appears on the display:
•
After you select the unit press the scale returnsto:
•
Return to weighing according to chapter - 12.2.2.
Notice:
After turning on the scale, it always starts with the basic unit.
19
13.5.
Temporarily selectedunit
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.
20
14.
MAIN PARAMETERS
Users can adjust the scale to external ambient conditions (filtering level) or particular needs (autozero
operation, tare memory). These parameters are placed in <P1.rEAd> submenu.
14.1.
Setting a filtering level
Procedure:
•
Enter the submenu <P1.rEAd> and then:
1 - 4 - level of filtering
•
Bypressing select the filtering level you need
Notice:
Filtering level influences the time of stabilization. The higher the filtering level, the longer stabilization
time is needed.
Return to weighing:
