The "
TARE
" indicator will be on. As product is added only the weight of
the product will be shown. The scale could be tarred a second time if
another type of product was to be added to the first one. Again only the
weight that is added after tarring will be displayed.
When the container is removed, a negative value will be shown. If the
scale was tarred just before removing the container this value is the
gross weight of the container plus all product that was removed. The
zero indicator will also be on because the platform is back to the same
condition it was when the
ZERO
key was last pressed.
Press the
TARE
key again to remove the tare weight.
PRETARE:
This method allows you to enter a known value for the container weight
from the keypad. This is useful if all containers weigh the same, or if
the container is already full but the net weight is required and the tare
weight of the container is known.
Remove all weight from the platform, and press the
ZERO
key to zero
the display.
Enter the value for the Pretare weight
IN GRAMS!
including decimal
values (50.00). Using the keypad, press
Tare
to store the tare value.
The weight will show a negative value equal to the tare.
Note:
If you have the scale set to operate in a unit other than grams,
the weight will be converted to that unit in the top window, but the
Pretare weight can only be entered in grams.
Place the container on the platform. The display will then show the
weight of the container minus the tare weight. Then when a full
container is placed on the platform the tare value will be subtracted
from the gross weight displaying only the net weight of the contents.
PARTS COUNTING
SETTING UNIT WEIGHT
In order to count parts, it is necessary to know the average piece weight of
the items to be counted. This can be done by placing a known number of the
items on the weighing platform and letting the scale determine the average
unit weight (Sampling), or by manually entering 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
key in the number of items being weighed. The scale will then divide
