COUNTING WITH ACCURACY ENHANCEMENT
When counting parts that are not uniform in weight, you can periodically update the
average piece weight (APW) and thereby increase the accuracy. Each time the
count
key is pressed, the scale will update the APW as long as the additional weight is less
than or equal to the previous sample weight. If the added weight is more than 100%
of the previous sample, the APW will not be updated. For example, if you start with a
sample size of 10 pieces then add 10 more and press the
count key, the APW will be
recalculated based on a 20 piece sample. The next time you wanted to update the
APW you could add up to 20 pieces. If you added 11 or more to the original 10 piece
sample, the APW would not be updated and would continue to represent the original
10 pieces. To count using this accuracy enhancement feature, follow the procedure
below.
1. Place an empty container on the scale and press the zero or tare key.
2. Place a known number of pieces on the scale.
3. Enter the number of pieces you have placed on the scale.
4. Press the count key. Wait for the “OK” symbol, then slowly add pieces until the
displayed count is increased by 100% or less.
5. Press the count key. The scale displays “UPdAtE” and automatically calculates
a new average piece weight based on the larger number of pieces, and is
ready to continue counting.
If “UPdAtE” is not displayed, the additional pieces have exceeded 100% of the
previous sample weight and the APW will not be updated.
CAUTION: This accuracy enhancement feature is disabled if the average piece weight
has been scanned in from a bar code or entered via a computer.
REVERSE COUNTING OR KITTING
Using this feature, you can place a container full of parts (such as capacitors) on
your scale and count the number of parts removed. This is especially helpful when
kitting (counting out a certain number of parts to be packed together). To perform
reverse counting or kitting, use the following procedure:
1. Place a container full of parts you wish to count on the pan.
2. Press the zero key.
3. Remove a known number of pieces from the pan.
4. Enter the number of pieces removed.
5. Press the count key.
