SECTION 2. UNPACKING & INSTALLATION
2. 1. Unpacking
Unpack the container carefully. Examine the packaging and the device for any
damage, and report it to the shipper if there is any. Try to keep the scale upright.
Check for enclosures as follows:
Scale platform
Stainless steel pan
Weighing indicator
AC Adapter
Operation manual
Ni-MH battery (optional)
Note :
1. If any items are missing or any damage is discovered immediately notify your
place of purchase or a dealer.
2. Keep box and shock absorber pad after installation. They are required for
transportation.
2. 2 Installing the scale
The pillar is attached to the base using a bracket that must first be attached to the
base frame using the 4 bolts supplied. The Pillar is secured to the bracket using 2
set screws. The cable from the base to the indicator module is run through the tube,
out through the plastic support at the top. Excess cable can be stored within the
tube.
The VC Series comes with a stainless steel platform packed separately. Place the
platform in the base.
Attach the indicator module to the pillar by sliding it over the bracket with the flanges
engaged in the groves on the base. Attach the cable from the base to the
connector on the rear of the indicator.
2. 3 To Level the Scale
Level the scale by adjusting the four feet. The scale should be adjusted such that the
bubble in the spirit level is in the centre of the level and the scale is supported by all
four feet. If the scale rocks readjust the feet.
The scale must be level for proper operation. Use the 4 level adjusters located at
the 4 corners of the scale main unit to adjust the horizontal position of the scale
until the bubble of the bubble level lies within the red circle. Ensure that the
scale sits solidly and does not wobble due to uneven adjustment.

the battery
5. 2 Basic operation
5. 2. 1 Zero the scale
When there is no item on the scale but reading is not zero, press the
key to turn on ZERO indicator, When the weight goes over 2% of the full
capacity, scale will do tare operate.
5. 2. 2 Tare
Put container on the platter, once the weight reading is stable (○indicator
turn on), press the key, the TARE indicator will be on and the
container’s weight will be deducted. When it is time to clear the TARE, take off
the container, and press key again. The container weight must more
then 2% of capacity, otherwise, scale will do zero operate.
.
5. 2. 3 Overload Warning
Please do not add item that is over the maximum capacity. When reading
“0-err“ and hear beeping sound, remove the item on the platter to avoid
damage to the load cell.
5. 3. Unit weight set
5.3.1 Sampling unit weight
In order to do parts counting it is necessary to know the average weight of the
items to be counted. This can be done by weighing a known number of the
items and letting the scale determine the average unit weight or by manually
inputting a known weight using the keypad.
Weighing a sample to determine the Unit Weight
To determine the average weight of the items to be counted it will be necessary
to place a known quantity of the items on the scale and then to key in the
quantity being weighed.

VC series bench scales Technical Manual
- 7 -
The scale will then divide the total weight by the number of samples and
display the average unit weight.
Zero the scale by pressing the key if necessary. If a container is to be
used, place the container on the scale and tare as discussed earlier.
Place a known quantity of items on the scale. After the weight display is stable
enter the quantity of items using the numeric keys followed by key. The
number of units will be displayed on the "Quantity" display and the computed
average weight will be shown on the "Piece Weight" display.
As more items are added to the scale, the weight and the quantity will
increase.
If the scale is not stable, the calculation will not be completed. If the weight is
below zero, the quantity display will show negative count.
When LIGHT (unit weight window) indicator flash, this means current unit
weighing it too low for this specification scale, please try to use other
specification scale, otherwise, you will can’t get accurate count data.
*if you input a incorrect data, press key to clear.
5.3.2 Entering a known unit weight
If the unit weight is already known then it is possible to enter that value using
the keypad.
Enter the value of the unit weight using the numeric keys followed by pressing
the key. The "Piece Weight " display will show the value as it was
entered.
The sample is then added to the scale and the weight will be displayed as well
as the quantity based upon the unit weight.
When LIGHT (unit weight window) indicator flash, this means current unit
weighing it too low for this specification scale, please try to use other
specification scale, otherwise, you will can’t get accurate count data.
*if you input a incorrect data, press key to clear.
5.3.3 resample
After completing the memorizing, you add the sample more and have new unit
weight value. This is resample function.
Add some samples, press key. Weight, Unit weight and quantity
displays light with beep, the memory is updated. Add the samples more and
more repeating the above operation, then more precise average unit weight

display. Press key. Go back to working area.
In case that only one point (13.Pn. 1) is selected to set, low limit value shows
after press key at once go back to working area.
5.5.3 Comparing ( how limit function work )
Suppose two limits have been set;
When the quantity is under the low value, it is ranked as “ LO “
When the quantity is between the low value and the high, it is ranked as “ OK “
When the quantity is over the high value, it is ranked as “ HI “
Notes
# Such settings as lower limit value >= Higher limit value will be error.
# Comparative judgment condition;
At one point(13.Pn. 1) :
L O : v a l u e < lower limit.
OK: lower limit =< value.
At two point(13.Pn. 2) :
LO: value < lower limit
OK: lower limit =< value =< higher limit
HI : higher limit< value
# We get beep sound in response to comparing result.
The condition is selectable by function set.
