3.9 Using Reverse Sampling for Counting, Method 1
3.9 Using Reverse Sampling for Counting, Method 1
Method 1 or 2 are chosen in the
Service Menu. See the Service
Manual for instructions. Reverse sampling occurs when you place an unknown number of items on
the scale, determine a piece weight (by method 1 or 2), and the scale counts
items as they are removed from the scale.
Method 1 and 2 are slightly different. Method 1 results in negative counts as
parts are removed. Method 2 results in positive counts as parts are removed.
Method 1 is explained below, method 2 in the next section.
Method #1 (Default setting)
1. Place full container on the scale. (entering an accurate tare weight will
allow you to determine the number of parts in the container)
2. Press SAMPLE . . .
ADD XXX is displayed.
3. Remove an unknown number of parts from the container. Once stable
the scale will acknowledge that the weight is less then initial zero and
the message
Add XXX will return.
4. Add the number of parts shown back into the container. If SAMPLE
TYPE is set to DRIBBLE mode, press the
SAMPLE key.…
The scale will calculate the piece weight and display the number of
parts based on the net weight on the scale.
5. To begin reverse counting of parts, clear any entered tare weight,
place all the parts back into the container and press
ZERO . As parts
are removed, the count of items removed is displayed as a negative
number.
