Taking a discrete measurement allows for measurement, display, and
storage of a single time-averaged reading taken over the sampling period.
Discrete measurement values are stored to the memory (current Test ID)
and displayed on-screen for a period of four (4) seconds. See
Chapter 4,
Data Logging for more details on data logging and adjusting the log mode,
sample interval, and log settings.
1. Press the READ key (from the Pressure or Flow Measurement
screen).
2. Allow the manometer to stand undisturbed until the reading is complete
(time of completion is dependent on the time constant setting).
Note: Discrete measurements stored from the Pressure Measurement
screen will not contain flow data.
