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)
	581	+**Stability check**
559	559
560		-**Example2**
	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.
561	561
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.
	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.
563	563
564		-* Read the tare weight
	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).
565	565
566		-Step 1: Write H0000 into BFM7.
	590	+**Zero point judgment**
567	567
568		-Step 2: Place the packaging on the CH1 load cell.
	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).
569	569
570		-Step 3: Write H0001 into BFM6 to take the weight of the packaging as the tare weight.
	594	+**Filter function**
571	571
572		-* Set BFM7 = H00F1.
	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.
573	573
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.

589		-* **Filtering**
