The amplitude that step-length is adjusted for the balanced setup parameter of adjustment each time.Specifically, by the setup parameter of balance parameters plus default
Step-length as balance parameters adjusted, or using balance parameters multiplied by preset step-length as balance parameters adjusted.In this Shen
Balance parameters adjustment please be carried out according to single stepping in specific embodiment, i.e. balance parameters adjustment each time is equal before adjustment
Add 0x03 on the basis of the original value of parameter that weighs.
When making the error code information of the second electric signal be less than or equal to error threshold value by balance parameters adjustment, stop equal
Weigh parameter optimization, and balance parameters adjusted are saved.Such as, when by balance parameters adjustment so that number of bit errors is reached 0 after, stop
Balance parameters optimization, balance parameters adjusted are saved, and the balance parameters after preservation are used as the equal of optical mode block transmission signals
Weighing apparatus adjustment.
