6.2.1 Preset Tare
• The user can enter a preset tare value if the display is at zero or gross
weight. Enter the value for preset tare using the keypad, then press the
[Tare] key to set the preset zero value.
• If the display was at zero the weight will show a negative value equal to
the preset tare value entered and the “Net” indicator will be on. If a
weight was on the platform then the preset value will be subtracted
from the weight, displaying the NET weight only.
6.3 PARTS COUNTING
6.3.1 Setting Unit Weight
In order to do parts counting it is necessary to know the average weight of the items
to be counted. This can be done by weighing a known number of the items and
letting the scale determine the average unit weight or by manually inputting a
known unit weight using the keypad.
A. Weighing a sample to determine the Unit Weight
To determine the average weight of the items to be counted, you will need to
place a known quantity of the items on the scale and then to key in the
number of items being weighed. The scale will then divide the total weight by
the number of items and display the average unit weight. Press [CE] anytime
to clear the unit weight.
• Zero the scale by pressing the [Zero] key if necessary. If a container is to
be used, place the container on the scale and tare by pressing [Tare] as
discussed earlier.
• Place a known quantity of items on the scale. After the weight display is
stable, enter the quantity of items using the numeric keys and then
press the [Smpl] key.
• The number of units will be displayed on the "Count" display and the
computed average weight will be shown on the "Unit Weight" display.
• As more items are added to the scale, the weight and the quantity will
increase.
• If a quantity which is smaller than the sample is placed on the scale,
then the scale will automatically enhance the Unit Weight by re-
calculating it. To lock the Unit Weight and avoid re-sampling, press [U.
Wt./Units].
