3.2Counting Mode
In Counting mode, you can do the simple weighing tasks mentioned in Simple
Weighing Mode on page 15, input a piece weight by keypad or by sampling the weight
of a known quantity of the items, and accumulate the quantity of different items. The
scale will display weight, piece weight, count of the items, and send data to RS232
interface.
3.2.1Counting Information
If there is no piece weight, the scale will not go into count mode, it will display ------ in
the COUNT window.
Once a piece weight is established it remains active until another piece weight is
automatically calculated by a sampling process or when input from the keypad.
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.
It is recommended that 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.
The minimum piece weight must be greater than or equal to:
3.2.2Counting 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.

The count is added into memory and following is an example
of what is
briefly displayed:
Add.xxx is displayed in the PIECE WEIGHT window. xxx = the number
of accumulations. You can accumulate up to 999 times. In this example
there has been only 1 accumulation.
The total accumulated count is shown in the COUNT window. In this
example the number of pieces counted is 1420.
The WEIGHT window shows the piece weight memory used for this
count. In this example PLU3 was used. If you are using a temporary
piece weight instead of a memory channel, TMP is displayed instead.
The display automatically returns to the normal counting mode after
three seconds.
3.Remove the items, allow the scale to return to zero and add more pieces to
count. Press the Add Tot key to accumulate the counts. Repeat this step until
all the pieces you want to count have been weighed and accumulated.
4.To view the accumulator data, press the Disp Tot key …
Below is an example of what is displayed:
You can see that a total of four accumulations have occurred, a total of
5642 pieces have been counted and that the piece weight stored in the
PLU3 memory location was used.
5.To clear the accumulator, press the Clear key while the accumulated data is
displayed.
B140 Counting Scale User Instructions21
Page 22
6.The scale will not accumulate more than 999 times or 999999 counts. If this
occurs the display will show ERR01. This means the display is over range.
(1) Remove the counted items from the scale and let the scale return to a stable
condition before you count more items and perform the next accumulation.
(2)There are nine accumulator memories for nine different items; PLU1 - PLU8 piece
weight channels and a temporary piece weight. That means different piece weights
have their own accumulator memory.
3.3RS232 Interface and RTC (Real Time Clock)
The RS232 interface is optional. When it is installed current data can be sent to this
port by pressing the Print key. The hardware real time clock (RTC) and backup battery
are also optional. If the RTC is installed, you only need to modify the date and time
when they are not correct. If RTC is not installed, a software RTC can be used. You
need to set the date and time every time the scale is reset. If the scale’s ID, date or time
are active, they can be printed out. The format is similar to the examples below:
You should periodically calibrate your scale to ensure accuracy. Follow these steps to
calibrate the scale.
Before a two-point calibration (zero and span) you should have on hand at least 10%
of the scale capacity in standard test weights. 100% of capacity is best. You should
have at least 20% of scale capacity if zero-point and two span points are selected to be
calibrated. Again, 100% of capacity is best.
Set the calibration switch to the ON position for calibrating. The switch is located on the
bottom of the scale in a round depression in the base. Push the slide switch, shown in
Figure 4.1, to the position shown for calibration mode.
You can escape the calibration procedure at any time by pressing the ON/OFF key.

When the current working voltage is lower than 5.7V, Lo.Bat will shown
in the WEIGHT window.
When the voltage is lower than 5.5V, Lo.Bat will shown in the WEIGHT
window and the beeper will sound for approximately two minutes before
the scale turns itself off.
The A to D counts for an empty scale should be between 5000 and
100,000. This should be a positive number. The A to D counts for a scale
at full capacity should be above 300,000. If the A to D counts are outside
of these ranges or calibration and normal weighing cannot be done you
scale’s loadcell has been permanently damaged.
