Damp Rate Select
Adjustable exponential type damping is available to steady the
display when measuring pulsating pressures. The HHP360 has a
range of damping rates; 0.1, 0.2, 0.5, 1, 2, 5, 10, or 25 seconds.
Damping is done by averaging new data from the pressure sensor
against previously collected data. The microprocessor collects data
from the sensor every 0.1 seconds. The display updates every 0.5
seconds, showing the current 0.1 second pressure reading. When
set at 25 seconds, the display updates every 0.5 seconds with the
average of the previous 25 seconds readings. Therefore, it takes up
to 25 seconds from the time pressure is applied until the
manometer displays the full scale applied pressure. Min/Max
display updates every 0.1 seconds.
To set the damp rate:
