2. PREPARAT ON
2.1. Before using the scale
1. Please keep the scale in a cool and dry place. Do not store at high temperatures.
2. Do not allo any liquids to come into or contact ith the scale. If it is happened,
ipe the scale dry ith a cloth.
3. Avoid objects impacting ith the scale. Do not drop loads onto the scale or subject
the eigh pan to any strong shock loads.
4. The load placed on the eigh pan must not exceed the maximum eighing
capacity of the scale.
5. If the scale is not going to be used for some time, please remove the dry cell
batteries, clean it and store it in a plastic bag in dry conditions. A desiccant sachet
may be included to prevent moisture build up.
6. Do not mix different types of dry battery or mix used dry batteries ith ne dry
batteries.
2.2. Preparing the scale for use
1. Unpack the scale carefully and place it on a firm surface. Fit the platter and
assemble and fit the cover on the scale and remove any packing materials that
may be underneath. The scale may come ith a protective film on the display and
button panel hich should be removed for clear reading of the display.
1. For accurate eight readings locate the scale on a firm level surface free from
vibrations.
2. Avoid operating the scale in direct sunlight or drafts of any kind.
3. Remove any eight that might be on the eigh pan before the scale is s itched on
and avoid leaving eight on the pan for long periods of time.
4. Once the scale has been s itched on, it ill go through a LCD display test and then
re-zero to be ready for use.
5. For best accuracy s itch the scale on for 15~20 minutes before use.
6. Please note hen the symbol appears on the screen, the dry batteries need
to be replaced.
7. All goods eighed should be placed in the centre of the eigh pan for accurate
eighing. The overall dimensions of the goods being eighed should not exceed
the dimension of the eigh pan.
8. The acceleration due to gravity varies around the orld. The force on the scale is a
product of the gravity value and the mass placed on the scale to eigh. As the
gravity value can vary in different orld locations so can the eight displayed for
the same mass. The Scales have been calibrated for a gravity value (acceleration
due to gravity) of g=9.803 m/s2. Discrepancies in readings at the location of
installation could be due to a different gravity value and adjustment of the scale
calibration or gravity value may be needed for the scale to be most accurate at your
location.
9. The scale is equipped ith a transportation protection device. This locks the scale
during transportation and handling to avoid damage. Before use this scre must be
removed.
10.The WS5 is supplied ith a ind shield to ensure a stable reading in the presence
of air currents. This must be assembled before use.

2. Place the object(s) to be eighed in the container, the scale ill sho the net
eight value (or quatity in pcs mode) of the object(s).
3. Remove the container and contents, and the display sho s the negative eight
value of the container. Press the
T
key to clear the eight value of the
container, and the tare indication goes off. If the tare indicator does not go off at
this point, press the
→0←
ON
key.
4. Tare continuously (Press the
T
key, hen eight is added or deducted on the
eigh pan so the next amount added or removed can be eighed).
5. Tare value = The full capacity (The scale can be tarred continuously to the full
capacity).
5.2.4. Simple weight calibration
1. Press the key and hold pressed for 3 seconds to perform simple eight
calibration. The display sho s the predefined calibration eight to put on the scale.
2. Place the displayed eight on the scale, hen the display becomes stable the
calibration is automatically completed.
3. The value for the calibration eight is factory set.
5.2.5.Operating mode switching
1. Press the
MODE
key to s itch bet een eighing mode, counting mode and
percentage mode.
Page 9

WS5 Operator Manual Rev 6.6.19
5.2.6.Unit weight function
1. Press the
H R
key to s itch bet een unit eight display and pcs mode display. The
eight of a sample should be greater than 0.2 of a scale division. When the sample is
too small --or- is displayed.
5.2.7.Counting mode
1. Press
MODE
key to select piece unit (pcs), and enter the counting mode. When the
counting mode is reached (the Pcs annunciator is displayed) the scale ill sho
C10 pcs depending on the previous use of piece counting.
2. If a container is to be used to hold the pieces during counting then place the empty
container on the scale and press the tare key. The indicator sho s ---- and
then 0. If a container is not to be used, skip this step.
3. Press
P
CS
key to select the counting sample size 10, 20, 50, 100, or 200, and
the display sho s C10, C20, C50, C100 or C200 pcs.
4. Place the quantity of samples set above on the eigh pan or in the container if one
is used, then press . The display sho s “----”. After the eight becomes
stable, the scale sho s the quantity of the samples. When the samples are removed
the scale sho s 0. After the sampling process is complete, put the goods to be
counted on the eigh pan or in the container and the screen sho s the quantity of
the goods on the scale.
5. If more items of the same type are to be eighed ith a different container or
ithout a container hen previously a container as used, press the
T
key
ith the empty container or scale before adding the components. This ay
containers of different tare eight can be repeatedly filled ith the same type of
components.
6. If the items to be counted are different, repeat the above proceedure from step 2.
7. Press the
H R
key to s itch bet een Unit Weight Display mode and PCS mode
display.
8. The scale remembers the sample unit eight hen turning the scale off. To enter the
counting mode directly ith the same sample unit eight hen the scale is s itched on
press the
P
CS
key hen the scale has completed its po er on self check before
pressing any other button.
9. If the quantity of the items eighed is larger than the resolution times 5 (pcs), the display

MODE
key to select Percentage mode. The display sho s 100 %.
2. Press the
P
CS
key to select 100.0 % or 100.00 % (2 decimal places).
3. Place a load on the scale equal to 100% of the eight or items. and press the
key, The display sho s “----” and the % symbol flashes. When the % stops flashing
the sampling procedure is complete and eighing in the % mode is possible.
4. Place the eight to be measured on the scale. The percentage this eight is of the

ill use the same selected sample percentage, hen entering the percentage mode
next time. To enter the percentage mode directly ith the same sample eight hen the
scale is s itched on press the
P
CS
key hen the scale has completed its po er on
self check before pressing any other key.
5.2.9.Notes
●In the counting or percentage mode, press the key or the
