5.10.2 Part Accumulation and Negative Counting - Without Recalling an Item Code
The DC-200/300 counting scale is fully capable of part number inventory tracking and maintenance using the
stored item code function internal to the scale software. See Section 5.11.5 Adding Part to and Subtracting Parts
From Inventory. Additionally, the scale has the capability to acquire the total number of parts using the
accumulation or reduction function of the scale (similar to the add/subtract functions of a calculator).
Part Accumulation
To find the total accumulated quantity of similar containers filled with parts, use the accumulation procedure
detailed below. This does affect the inventory quantity for this item in the scale’s memory. To add or subtract
from inventory, see Section 5.11.5.
1. Conduct a sampling process (Section 5.5.1) to determine the unit weight of the pieces.
2. Enter the known tare weight, or place an empty container on the scale to perform tare function
(Section 5.3).
3. Place container 1 (full of parts) on the scale.
4. Press the
+ key to store the total in container 1. The memory annunicator% is now illuminated. The
weight display briefly shows
totAL and the quantity display shows the total pieces in the first container.
Note: If SPEC 31 PC/PRN OUTPUT is set to “2: BY +/-/PRINT KEY”, a label will be printed when you press the + key. The label
will show the quantity in the container currently on the platform, not the accumulation. If SPEC 14 AUTO EXIT FROM ADD MODE
is set to “0: NO”, the scale will not automatically exit from displaying the total amount. To return to the weighing mode, press the
CLEAR key.
5. Remove container 1 and place container 2 (full of parts) on the scale.
6. Press the
+ key (total is equal to container 1 plus container 2, etc).
7. Continue with the remainder of the containers to be counted. The total number of parts stored in all the
containers will be stored in the accumulation register.
8. To print a label in the default label format showing the total, press the
* REPRINT key. This will also clear
the accumulation register. The memory annunciator% is no longer illuminated.
Negative Counting
Just as you can count by adding parts to the scale, you can also count by removing parts from the scale. This is
called “negative counting” because a negative weight is displayed while counting. Contrary to what may seem
intuitively logical, you do not use the (
-) key to do negative counting. The (-) key is only used to delete an entry
in accumulation mode that you want to erase. This procedure does not affect the inventory quantity for this item
stored in the scale. To reduce inventory, see Section 5.11.5.
Note: To utilize the negative counting feature, SPEC 2 - NEGATIVE COUNTING must be set to “1: YES”.
There are two ways to do this depending on whether at the end you want to see the total amount remaining in the
container or the total amount removed from the container.
Counting Out of a Full Container - See Total Amount Remaining in the Container
To carry out this operation you must know the tare weight ahead of time.
1. Place the full container on the scale. Press the
TARE key.
2. Remove a 10 piece sample to the container and press the
PIECES key. After the unit weight has been
calculated, return the 10 piece sample to the container.
3. Remove a number of parts from the container and press the
+ key. The memory annunicator% is
illuminated and the display shows the quantity of parts taken out.
4. Remove a number of parts from the container and press the
+ again. The memory annunicator% will be
illuminated and the display shows the quantity of parts removed.
5. If at the end of the procedure, if you want to see how many are still in the bin you first have to know the
tare weight of the bin or container. After removing the parts you want to take out of the bin, simply
digitally enter the tare weight of the bin and press the
TARE key. The scale will display how many parts
were left in the bin. To print a label to put on the bin showing the new, lower, total quantity in the bin,
press the
+ key.
Note: If SPEC 14 AUTO EXIT FROM ADD MODE is set to “0: No”, the scale will not auto exit from displaying the total amount. To
return to the weighing mode, press the CLEAR key.
