Toggle Between Scales, Entering Unit Weights

6.2Toggle Between Scales

To switch the displays from Scale 1 through Scale 4, press the SCALE key when in weighing mode. Only scales present are selected. For example, a two-scale system switches between Scale 1 and Scale 2 only. In a four-scale conﬁguration, the SCALE key functions as follows:

1.Press SCALE key to change from Scale 1 to Scale 2.

2.Press SCALE key to change from Scale 2 to Scale 3.

3.Press SCALE key to change from Scale 3 to Scale 4.

4.Press SCALE key to change from Scale 4 to Scale 1.

NOTE: Scale number assignments are set using SPECs 16 and 17.

6.3Toggling Between Net and Gross Weight

To toggle between net and gross weight, a tare value must be entered into the scale (see Section 6.1). NOTE: SPEC 25, bit 0 (Gross Mode Available) must be set to 0 (default) to enable gross mode.

After a tare value is entered into the scale, items placed on the scale will cause the NET annunciator to illuminate and allow toggling between net weight and gross weight.

An example of toggling between net weight and gross weight is shown below:

1.Place 0.5 lb weight on the scale and then press TARE once. The WEIGHT display should show 0.000 lb.

2.Place another 0.5 lb weight on the scale. The scale WEIGHT display should now show 0.500 and the NET annunciator should be illuminated.

3.Press NET/GROSS. The WEIGHT display should show 1.000 and the GROSS weight annunciator is illuminated. The UNIT-WEIGHTand the QUANTITY displays go blank.

4.Press NET/GROSS. The WEIGHT display now shows 0.500 and the NET weight annunciator is illuminated.

6.4Entering Unit Weights

Entering unit weights can be done either by sampling, as described in Section 6.4.1, or by key entry as described in Section 6.4.2.

SPEC 0, bit 0 (Piece Weight Selection) works in conjunction with the UNIT-WEIGHTdisplay. Setting the bit to 0 speciﬁes that the UNIT-WEIGHTvalue shown is per 1000 pieces and the UNIT WT PER 1000 annunciator is lit. Setting bit 0 to 1 speciﬁes that the unit weight value shown is per one piece (A.P.W.).

NOTE: SPEC 4, bits 1 and 2 (Insufﬁcient Sample Level) control unit weight sampling. The default value is 0.1 percent.

6.4.1Unit Weight Operation by Sampling

Unit weight operation by sampling is accomplished by placing a known quantity of pieces to be sampled on the scale and then pressing the PIECES key. The scale calculates a unit weight based on the capacity of the scale compared to the weight of the sample.

1.Press REZERO to zero scale.

2.Place 10 pieces of the item to be sampled on the scale.

3.Press PIECES key then wait a few seconds for the computation. If the sample weight is sufﬁcient (INSUFF annunciator is off), the WEIGHT display shows the total sample weight; the UNIT-WEIGHTdisplay shows the unit or per 1000 weight for the 10 sample pieces (depending on the value of SPEC 0, bit 0, as described above); the QUANTITY display shows the number of pieces (10).

If the weight of the sample is insufﬁcient (INSUFF annunciator is on), add pieces to the initial sample until the INSUFF annunciator goes off.

•If SPEC 5, bit 2 (unit weight auto-recomputing), is set to 1, place required pieces on the scale. The scale automatically recomputes the unit weight.

•If SPEC 5, bit 2, is set to 0, use the keyboard to enter the new number of sample pieces then press the PIECES key again to recompute the unit weight.
