6.4.2Unit 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.With the display in the weighing mode, use the keyboard to enter the known unit weight, for example,

200.00.

NOTE: The setting for SPEC 0, bit 0, determines whether the value entered is per piece (A.P.W., if set to 1) or per 1000 pieces (if set to 0).

2.Press UNIT WEIGHT key to enter the unit weight.

3.Place a 2 lb. weight on the scale. The scale displays the quantity for the weight placed on the scale. For example, the WEIGHT display reads 2.000, the UNIT-WEIGHTdisplay reads 200.00 (per 1000 pieces), and the QUANTITY display reads 10).

6.4.3Clearing Unit Weight

To clear a unit weight:

1.Remove weight from scale.

2.Press the CLEAR key.

6.5Part Accumulation and Reduction–Without Recalling an Item Code

The DC-190 counting scale is capable of part number inventory tracking and maintenance using the stored item code function of the scale software (see Section 7.0 on page 30). Additionally, the scale has the capability to acquire the total number of parts using the accumulation or reduction function of the scale (similar to the add/ subtract functions of a calculator).

6.5.1Part Accumulation

To find the total accumulated quantity of similar containers filled with parts, use the accumulation procedure detailed below. Six containers are used in this example procedure; it is assumed that all containers are of the same weight.

1.Conduct a sampling process (see Section 6.4) to determine the unit weight of the pieces.

2.Enter known tare weight, or place empty container on scale to perform tare function (see Section 6.1).

3.Place Container 1 (full of parts) on the scale.

4.Press the + key to store the total in Container 1. The MEMORY annunciator lights. The WEIGHT display briefly shows totAL and the QUANTITY display shows the total pieces in the first container.

5.Remove Container 1 and place Container 2 (full of parts) on the scale.

6.Press the + key (total is equal to Container 1 plus Container 2).

7.Continue with the remainder of the containers in the same accumulation method. The total number of parts stored in all six containers will then be stored in the accumulation register.

8.To view the total, make sure that the scale platter is empty and press the + or key.

9.To clear the total, press the * key. The MEMORY annunciator is not illuminated.

NOTE: If SPEC 32, bit 1 (Auto Exit from Part Accumulation and Reduction Mode) is set to 0, the scale will not auto exit from displaying the total amount. To return to the weighing mode, press the CLEAR key.

6.5.2Part Reduction

Part reduction can be also be done by using the key while the scale is in the weighing mode and the MEMORY annunciator is on.

1.Conduct a sampling process (Section 6.4) to determine the unit weight of the pieces.

2.Place container to be tared on scale and enter the tare weight (Section 6.1).

3.Place Container 1 (full of parts) on the scale.

4.Press the + key to store the total in Container 1. The MEMORY annunciator lights. The WEIGHT display briefly shows totAL and the QUANTITY display shows the total pieces in the container.

5.Remove a number of parts from the container and press the key. The MEMORY annunciator is
