-You could choose whether the measured weight is net weight or gross weight. Net weight refers to the weight of the product itself, that is, the actual weight of the product after removing the weight of the outer packaging. The weight of the outer packaging is generally called the tare weight, and the gross weight is the total weight, which refers to net weight plus tare weight. |
|
543 |
+== **5.3 Function Instructions** == |

|
| 562 |
|
-* Tare weigh:t Refers to the weight of the outer packaging. |
| 563 |
|
-* Net weight: Refers to the weight of the product itself, that is, the actual weight of the product after removing the weight of the outer packaging. |
| 564 |
|
-* Gross weight: Refers to the total weight, that is, the weight of the product itself (net weight), plus the weight of the outer packaging (tare weight) |
| 565 |
|
-* Gross weight = net weight + tare weight |
|
545 |
+**Net weight measurement** |
| 566 |
566 |
|
| 567 |
|
-E.g: There is a product that is 10KG, the carton it is packed in weighs 0.2KG, and the total weight is 10.2KG. |
|
547 |
+It can be set to measure net weight or gross weight. The Net weight means the weight of the product itself, that is, the actual weight of the product without its external packaging. |
| 568 |
568 |
|
| 569 |
|
-* Net weight=10KG |
| 570 |
|
-* Tare weight=0.2KG |
| 571 |
|
-* Gross weight=10.2KG |
|
549 |
+The weight of the packaging is called the tare weight. The gross weight is the total weight, namely the net weight plus the tare weight. |
| 572 |
572 |
|
| 573 |
|
-E.g: Use CH1 to measure the value to display the net weight, and CH2 to select OFF. (If the weight of the outer package is known, you can skip the step of reading the tare weight). |
|
551 |
+1. Tare weight: weight of the packaging |
|
552 |
+1. Net weight: the weight of the product, excluding the packaging. |
|
553 |
+1. Gross weight: the net weight plus the tare of the product. |
|
554 |
+1. Gross weight= net weight + tare weight. |
| 574 |
574 |
|
| 575 |
|
-* Read the tare value |
| 576 |
|
-** Write H0000 in BFM7; |
| 577 |
|
-** Place the package on the CH1 weighing module; |
| 578 |
|
-** Write H0001 in BFM6, and take the current package weight as the tare weight. |
| 579 |
|
-* Set BFM7=H0001 |
|
556 |
+**Example 1** |
| 580 |
580 |
|
| 581 |
|
-**Stability check** |
|
558 |
+A product weighs 10kg and the carton contains it weighs 0.2kg, then its gross weight is 10.2 kg (net weight=10kg, tare weight=0.2kg, gross weight=10.2kg) |
| 582 |
582 |
|
| 583 |
|
-When placing the item on the weighing module to measure the weight, the user can use the stability check function to know that the current measurement value is stable. |
|
560 |
+**Example2** |
| 584 |
584 |
|
| 585 |
|
-* If the variation range of the measured value is within the stable range #22 set by the user, the #4 stable bit of the measured value will be set to 1. |
| 586 |
|
-* When the variation range of the measured value exceeds the set stability range, the #4 stable bit of the measured value will be set to 0, until the stability check time #21 is within the stable range, the #4 stable bit of the measured value will be set to 1 again. |
|
562 |
+Use the measured value at CH1 as the net weight. If you know the weight of the packaging already, you can skip the step of reading tare weight. |
| 587 |
587 |
|
| 588 |
|
-E.g: The stability check time is set to 200ms, and the stability check range is 10. When the change range exceeds 10, the measurement value is unstable, that is, the #4 stable bit of the measured value will be set to 0. When the beating range is within 10 within 200ms, the stable bit of the measurement value will be set to 1 again. (It is recommended that the user should judge whether the current measurement value is stable before performing control). |
|
564 |
+* Read the tare weight |
| 589 |
589 |
|
| 590 |
|
-**Zero point judgment** |
|
566 |
+Step 1: Write H0000 into BFM7. |
| 591 |
591 |
|
| 592 |
|
-You could use the zero point judgment function to know that the item has been removed from the weighing module. You could judge that the measurement value is stable and the Bit is 1, which means that the item has been removed from the weighing module, and you could perform the next step at this time. (The zero point weight Bit in the zero point judgment range is 1). |
|
568 |
+Step 2: Place the packaging on the CH1 load cell. |
| 593 |
593 |
|
| 594 |
|
-**Filter function** |
|
570 |
+Step 3: Write H0001 into BFM6 to take the weight of the packaging as the tare weight. |
| 595 |
595 |
|
| 596 |
|
-The average value is the function of summing and averaging the read values to obtain a slowing value, but the environment used will have unavoidable external force factors, which will cause the read value to have a sharp change in the surge value. The change also becomes larger. The function of filtering is not to include the sharply changing surge value in the aggregated average, and the obtained filtered average value will not be affected by the sharply changed surge value. |
|
572 |
+* Set BFM7 = H00F1. |
| 597 |
597 |
|
|
574 |
+**Standstill check function** |
|
575 |
+ |
|
576 |
+When an object is placed on the load cell to measure its weight, you can use the standstill check function to know whether the current reading has been stabilized. |
|
577 |
+ |
|
578 |
+* If the measured value shifts within the range (BFM 22) of standstill check set up by the user, BFM4’bit 4 will be set to “1”. |
|
579 |
+* If the measured value shifts beyond the range for standstill check set up by the user, bit4 will be set to “0”. They will be set to “1” again when the range is returned to the set range. |
|
580 |
+ |
|
581 |
+**Example** |
|
582 |
+ |
|
583 |
+The measuring time is 10ms, the times of standstill check is 10, and the range for standstill check is 1,000. When the range for standstill check exceeds 1,000, the reading is considered unstable, i.e. BFM4’bit4 will be set to 0. When the measuring time is within 100ms (10 × 10ms) and the range returns to be within 1,000, BFM4’bit4 will be set to 1 again. We recommend you check if the measured value is stable enough before operating it. |
|
584 |
+ |
|
585 |
+* **Zero detection function** |
|
586 |
+ |
|
587 |
+Users can use this function to know whether the object has been removed from the load cell. If the BFM4’bit4 is 1, and the BFM4’bit0 and bit1 are 1 as well, the object has been removed from the load cell already, and you can proceed to the next step. |
|
588 |
+ |
|

|
590 |

646 |
Calibration without weights is performed by the zero point of the sensor and the maximum range of the sensor. The accuracy is related to the sensor specifications and depends on the sensor sensitivity (mV/V). |
| 647 |
647 |
|
| 648 |
648 |
Example: The sensitivity of LAB-B-B sensor is 2.0±10%mV/V, and there may be a maximum error of 10%, so it is best to use a sensor with a small sensor sensitivity error to use this function. |
