Meta Index
This setting tells X-Link what other measurement this
Meta
measurement refers
to.
Why use meta measurements? If you had set up an hourly averaged
temperature measurement, a
Meta
measurement could be set up to be the daily
average of all those hourly readings.
Measurement M1
(used for Hourly Temperature)
Measurement Type: Analog
Analog Type: 0-5VA
Measurement Interval: 1 hour
Averaging Time: 1 hour
Sampling Interval: 1 second
Measurement M2
(used for Daily Temperature)
Measurement Type: Meta
Meta Index:
1 (meaning it refers to measurement M1)
Measurement Interval: 24 hours
Averaging Time: 24 hours
Sampling Interval: 1 hour
When scheduling meta measurements, take care that they occur at the same
time or after the measurement they reference. If the meta and the reference are
scheduled for the same time, X-Link will try to delay the meta measurement until
the reference completes.
7.1.4.24.
Manual Entry
Manual entry measurement types allow the user to enter a reading manually.
That value becomes the reading of the measurement. X-Link will store the user
entered value in the
Offset
field.
To enter a manual entry reading, use LinkComm's Calibrate button.
7.1.4.25.
Internal Temperature
Internal Temperature
measurements use a temperature sensor installed inside
X-Link. Every X-Link comes with a built in temperature sensor. The reading
provided is in degrees Celsius. To convert from Celsius to Fahrenheit set the
slope to 1.8 and the offset to 32.
7.1.4.26.
Accubar Pressure And Temperature
Sutron provides Accubar Barometric Pressure and Temperature sensors which
can be connected to X-Link via an internal connector.
By default, the sensors produce an atmospheric pressure reading in millibars and
a temperature reading in degrees Celsius. To convert them to other units, please
