101364     Model FT2 
    For example if we enter a filter of 0.8, the weight ratio for new average is: 
    New average = (80% new sample) + (20% last average)  
 
    Filter range is 0.01 to 1.0, 0.01 being a high filter value and 1.0 = no filter.

This is the upper flow limit alarm value that can be associated with a discrete output.  An alarm 
code is generated when the flow value exceeds this limit.  If no checking is needed, this value 
should be set to zero. 
 Press OK (F4) to accept the value.

This is the lower flow limit alarm value that can be associated with a discrete output.  An alarm 
code is generated when the flow value is below this limit.  If no checking is needed, this value 
should be set to zero.
