quantity using the numeric keypad before pressing the
PCS
key.
4. To improve the accuracy of the Unit Weight calculation, add another sample of the same pieces. This
second sample should be of a number of pieces equal to or fewer than the first one. Press the
PCS
key.
(
NOTE:
If Specification 53, Bit 2 is set to the default setting of 1: Automatic, the scale will automatically begin
recomputing.)
The scale display will display
RECOMPUTING
for a few seconds, then automatically display the new total
Weight, Unit Weight, and number of Pieces.
NOTE
:
If you place too large a second sample on the platform, the error message
OUT OF RECOMPUTE RANGE, PLEASE
REDUCE SAMPLES
will appear. You can also tell if you are under the maximum recomputing sample size by observing
the bar graph along the bottom of the display. When it reaches all the way to the
MAX
marker on the bottom right-hand
side of the display, you have reached the maximum. Remove some of the pieces in the second sample until the number
of pieces is below that of the first sample.
If you place too small a sample on the platform for the scale to accurately calculate a Unit Weight, the
INSUFF indicator lamp will illuminate and the display will indicate how many more pieces have to be
added to the sample in order to be able to calculate the Unit Weight. Add the necessary pieces to the
sample until the scale returns you to the Normal Counting Mode screen. The screen will then show
RECOMPUTING
before showing the Unit Weight.
5. If you wish to continue to refine the Unit Weight, repeat Step 4, adding another sample.
6. When done with calculating the Unit Weight you can begin counting operations by placing a quantity of
the pieces to be counted on the platform. The scale will display the number of pieces as well as the Total
Weight, based on the Unit Weight established by the sampling process. To store this Unit Weight in the
DC-530’s memory associated with an Item Code so that you can recall it in the future, see Section 6.2.
7. To clear the Unit Weight, remove all weight from the scale platter and press the
C (Clear)
key.
5.5.2
Normal Counting Mode - Unit Weight Operation by Key Entry
Unit weight operation by key entry is accomplished by using the numeric keypad to enter the known value of the
Unit Weight and then pressing the
UNIT WEIGHT
key. An example of Unit Weight operation by key entry is
shown below:
1. Press the
REZERO
key to zero the scale.
2. With the display in the Normal Counting Mode, enter the known Unit Weight using the keyboard, for
example, 200.00.
(
NOTE:
the Unit Weight is entered and displayed per 1000 pieces. To enter a Unit Weight of 0.0125 lbs, for example,
multiply 0.0125 x 1000 = 12.5. For a Unit Weight of 0.0125, therefore, you would enter 12.5 on the numeric keypad.
When entering Unit Weights you must enter the decimal point where appropriate.)
3. Press
UNIT WEIGHT
key to enter the Unit Weight.
