AVERAGING PROPERTIES: Sets response time. The monitor
averages many transmit cycles in a boxcar integrator for a time period
defined as the Integration Period. At the end of the period the contents of
the boxcars are evaluated and a set of instantaneous values are declared.
These instantaneous values are placed into a moving average filter from
which an average value is derived. The user may set both the Integration
Period (response time of the instantaneous data) and the Integration Periods
in Average. Response time of the average data is the product of both
parameters.
CONTENTS: Integration Period (seconds)
Integration Periods in Average
(dimensionless)
MEDIUM PROPERTIES: Contains the expected extremes of
temperature and flow velocity in the stack or duct (medium) under
measure.
CONTENTS: Minimum Medium Temperature
Maximum Medium Temperature
Minimum Flow Velocity
Maximum Flow Velocity
CALIBRATION PROPERTIES: Establishes set points and error
tolerance for SPANHIGH, SPANLOW, and ZERO. Also establishes time
of day and duration of the automatic calibration cycle. Note that IP is an
acronym for Integration Period and that a phase of the automatic
calibration cycle is disabled when set to zero.
