General Counting Information
If there is no piece weight, the scale will not go into count mode.
Once a piece weight is established, it remains active until another piece weight
is automatically calculated by a sampling process.
After counting items, remove them and the display should return to zero. If not,
press the ZERO key.
A counting scale needs a minimum amount of weight to calculate counts with
accuracy. Salter Brecknell recommends the sample weight be a minimum of
0.1% of scale capacity. The sample weight is the total weight of your sample
items. The table below shows the minimum sample weights recommended to
guarantee the most accurate counts.
After entering the number of samples and pressing the Enter key, the count
window displays the number entered. If the piece weight window shows SPL
PCS, press the CLEAR key, and increase your sample weight.
Counting by Sampling
Follow these steps to count items using the sampling method.
For count accuracy all items should be uniform in weight. Errors in count will
occur if parts vary in weight.
1. Turn the scale on and zero the display, if necessary, using the Zero key.
Be sure the scale is displaying weight in your preferred unit of measure.
Change it using the Units key, if necessary.
2. Place a known number of objects on the scale. This is the sample
weight the scale will use to calculate a piece weight…
Weight of the items is displayed in the WEIGHT window.
3. Key in the number of objects you placed on the scale…
SPL.PCS
is displayed in the PIECE WEIGHT window and the number
you keyed in is displayed in the COUNT window.
