100ms (10 × 10ms) and the range returns to be within 1,000, bit4 and bit5 of CR#50 will be set to 1
again. We recommend you check if the measured value is stable enough before controlling it.

5.3.3 Determining Zero Point
You can use the zero point determination function to know if the object has been removed from the load
cell. If the bit4 and bit5 of CR#50 are 1, and the bit0 and bit1 are 1 as well, the object has been
removed from the load cell already, and you will be able to perform the next step of the control.

5.3.4 Filtering
The average value is a steady value obtained from the sum of the read values. However, due to
unavoidable external factors, the read values may be an acute pulse, resulting in fierce changes in the
