B. Entering a known Unit Weight

If the unit weight is already known then it is possible to enter that value
using the keypad.

Enter the value of the unit weight in grams, using the numeric keys
followed by pressing the
[U. Wt./Units] key. The "Unit Weight" display
will show the value as it was entered.

The sample is then added to the scale and the weight will be displayed as
well as the quantity, based on the unit weight.
6.3.2 Counting more parts

After the unit weight has been determined or entered, it is possible to
use the scale for parts counting. The scale can be tared to account for the
container weight as discussed in the earlier section.

After the scale is tared the items to be counted are added and the
"Count" display will show the number of items, computed using the total
weight and the unit weight.

It is possible to increase the accuracy of the unit weight at any time
during the counting process by entering the count displayed and then
pressing the
[Smpl] key. You must be certain that the quantity displayed
matches the quantity on the platform before pressing the key. The unit
weight can be adjusted based upon a larger sample quantity. This will
give greater accuracy when counting larger sample sizes.
6.3.3 Check‐counting

Check‐counting is a procedure to cause an alarm to sound when the
number of items counted on the scale meets or exceeds a number stored
in the memory by using the
[Pst] key.

The value to be stored is entered from the keyboard. Enter the numeric
value to be stored using the numeric keys. Then press the
[Pst] key to
store the value.

To clear the value from the memory and thereby turn off the check‐
counting feature, enter the value "0" and press
[Pst] .

During counting if the count is below the setpoint the
“Lo”
indicator will
be on, if it is equal to the set point the
“OK”
indicator will be on and if it is
above the limit the
“Hi”
indicator will be on.
6.3.4 Manually Accumulated Totals

The values (weight and count) shown on the display can be added to the
