5. SCALES ASSEMBLY
Remove the scale from factory packaging and place the scale on flat and
hard surface far from heat sources and next:
• Pull out the transport protections (applies only to scales with max.
capacity 6kg):
-5-
• Install the pan and the pillar (WTC/SW scales) according to below
drawing:
Assembly of scales WTC/S series
Assembly of scales WTC/SW series
Caution:
1. During assembly of the pillar in the WTC/SW scale put attention not to
“cut” display tape.
2. Before starting the weighing remove (tear off) foil protecting scale pan.
6. STARTING AND OPERATION
• After assembly (see point 5 of manual) place the scale on flat and
hard surface far from heat sources.
• Scale should be levelled by turning regulation feet. Levelling is correct
if air bubble is in central position of level indicator placed in upper
(left) part of scale casing:
-6-
• Turn on the supply with switch
,
• After turning on the supply, wait until scale test is finished,
• When scale test is finished in display window <WEIGHT kg>
mass indication equal to zero will be indicated and symbols
▼will be displayed above marks:
ZERO - indication precise zero
STA
- weighing result is stable
AC
- scale power supply from external A/C adaptor
• If weighing result is other than zero – press zeroing key.
7. SUPPLY
Retail scales WTC series use two power supply sources. Scale casing has
placed in lower (right) part of casing.
A/C adaptor socket and switch
Socket is used only for connection of external A/C adaptor provided with
scale.
Scale is equipped with accumulator 6V/4.5Ah. Max operation time of
accumulator when accumulator with accumulator fully charged is 60 hours
(without backlight)and around 24 hours with LED backlight on.
Scale software automatically checks state of accumulator charging. At high
high accumulator discharging symbol ▼is displayed above BAT mark in
display window <WEIGHT kg>. After about 30s display windows
<UNIT PRICE €/kg> and <TOTAL PRICE €> are switched off and
in display window <WEIGHT kg> message is indicated <Bat-LO>.

After pressing appropriate key, scale will return to weighing.
13. WEIGHING
Place on the pan weighed load. When symbol ▼ is indicated above STA
mark in display window <WEIGHT kg>, weighing result can be read:
13.1. Scale tarring
To determine net mass put load packaging and when indication is stable
(mass indication will return to zero, in display window
press key
<WEIGHT kg> symbol ▼ will be indicated above mark NET:
- 11 -
After placing the load, scale display will indicate net mass. Tarring can be
done many times in full measuring range of scale.
While using the tare function, pay attention not to exceed max measuring
range of scale. After removing load and packaging indication equal to sum
of tarred masses with minus sign will be displayed.
Notice:
Tarring process can not be carried out when there is negative mass
value or zero mass value on scale display. In such case display
window < WEIGHT kg> will indicate message <Err3>.
13.2. Scale zeroing
In order to zero mass indication press key
. In display window
<WEIGHT kg> symbols ▼ will be indicated above ZERO and STA.
Zeroing is the same as setting new zero point, which is treated by the scale
as precise zero. Zeroing is possible only when display state is stable.
Notice:
Zeroing display state is possible only in range up to ±2% of scale max
capacity. If zeroed value will be higher than ±2% of max capacity, display
window <WEIGHT kg> will indicate message <Err2>.
14. MAIN PARAMETERS
User can adjust scale to external environmental conditions (filer level) or
to his own needs (autozero function). These parameters are in group
<P1. rEAd>.These functions will help the user to adjust the scale to
environment al conditions in which scale operates.
- 12 -
14.1. Setting the filter level
Procedure:
• Enter to submenu <P1. rEAd> according to point 12.2 of manual,
and next:
0 - 4 - filter level depending on environment al conditions
Return to weighing:
See – point 12.2.2. – return to weighing.
Notice:
The higher filter level the longer time of weighing result stabilisation.
14.2. Median filter
Median filter is applied for eliminating short impulse disturbances
(e.g. mechanical shocks).
Procedure:
• Enter to submenu <P1. rEAd> according to point 12.2 of manual,
and next:

Fnnd
OFF - median filter operation on
On - median filter operation off
Return to weighing:
See – point 12.2.2. – return to weighing.
14.3. Autozero function
„AUTOZERO” function was introduced to ensure precise indications. This
function was applied to control automatically and to correct zero indication
of scale.
When function is active, consecutive results are compared in fixe periods
of time. If these results differ less than declared range of AUTOZERO
e.g. 1 division, scale will automatically go to zero and in display window
< WEIGHT kg> symbols ▼will be indicated above ZERO and STA.
When AUTOZERO function is on , each measurement starts from precise
zero. There are some special cases when this function interrupts in
measurements.
- 14 -
Example of that can be very slow loading of pan (e.g. load pouring ), in
such case correction of zero indication can also correct indication of real
load mass.
Procedure:
• Enter to submenu <P1. rEAd> according to point 12.2 of manual,
and next:
