Fluctuations in the airow output signal are normal. Laboratory research
indicates that dampening true uctuations will result in poor control and
a larger dead-band of operation. Therefore, the use of the dampening
lters in control devices is not recommended. Warnings indicate potentially
hazardous situations, which can result in property damage, severe personal
injury, or death if not avoided.
