CKG counting scales operation manual
Enter the value for the Tare weight using the keypad, press
TARE
to
store the tare value. The weight will show a negative value equal to the
tare.
Place the container on the platform.
The display will then show the weight of the container minus the tare
weight. Then when the full container is put on the platform the tare value
will be subtracted from the gross weight displaying only the net weight of
the contents.
If the value input is not consistent with the increment of the scale the
scale will round the tare value to the nearest value possible. For example
if a tare value of 10.3g is entered onto the 6Kg/0.5g scale then the
display will show -10.5g.
5. PARTS COUNTING
5.1 Setting 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.
5.1.1 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.
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
ZERO
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
-4-
followed by
SMPL
key. The number of units will be displayed on the
"Quantity" display and the computed average weight will be shown on the
"Unit 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.
5.1.2 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
U.weight
key. The "Unit 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.
5.2 Parts Counting
After the unit weight has been determined or entered it is possible to
use the scale for parts counting. The scale can be tared to account for
package weight as discussed in an earlier section.
After the scale is tared then the items to be counted are added and
the "Quantity" display will show the number of items computed using the
weight and the unit weight.
It is possible to increase the accuracy of the unit weight at any time
during the counting process by entering the count displayed then
pressing the
U.weight
key. You must be certain the quantity displayed
matches the quantity on the scale before pressing the key. The unit
weight will be adjusted based upon a larger sample quantity. This will
give greater accuracy when counting larger sample sizes.
