Damp Rate Select

Adjustable exponential type damping is available to steady the
display when measuring pulsating pressure or flow. The Smart
Manometer has a range of damping rates; 0.1, 0.2, 0.5, 1, 2, 5, 10,
or 25 seconds. Exponential damping shows approximately 70% of
a step change in pressure upon the next display update. When set
for 5 second time constant, it takes 5 seconds from the time of the
step change until the manometer displays the full value of the new
pressure.
