The current value of the time constant is adjustable. Available settings
include 1, 5, 10, 20, and 30 seconds.
Notes:

The time constant is the period over which the manometer averages
measurements. Example: with the time constant equal to ten (10)
seconds, the displayed reading represents the average of
measurements taken over the previous ten (10) seconds.

Increasing the time constant will serve to improve measurement
stability, particularly when measuring systems with fluctuating
pressures.
