1. Each channel set the input signal types, ranges, alarm value independently.
    
2. Each channel independently set digital filter time constant ,in order to improve the anti-interference ability effectively
    
3. Each channel independently set zero and full correction, effectively reduce the sensor error and improve the system measurement accuracy
    
4.  Level 2 parameters. Level 2 parameters controlled by the password, to prevent wrong operation. Have copy function, greatly reduce the workload of parameter Settings
    
5. Unused channels can be closed willfully.
