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.

LoFloAlm = 100 SCFM

CHG OK

F1 F2 F3 F4

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.

Press OK (F4) to accept the value.
