7.1.9. Measurement Two-Point Calibration
Changing the slope and offset of a measurement can be accomplished by using
the automated two point calibration. You will need to be able to affect the
sensor so that it can provide two different readings.
On the command line, type M1 CAL. This procedure requires that the sensor be
placed so that it provides one known value, then placed again to provide a
different known value. This procedure will affect both Slope and Offset of a
measurement.
7.1.10. Multiple Measurements Using the Same Sensor
You can set up multiple measurements with the same input. For example, to log
the daily rainfall and the rainfall during the last hour, set up two measurements:
one a precipitation rate with an interval of one hour, and another as
precipitation rate with an interval of one day.
To log the daily temperature and the hourly temperature, only one physical
temperature sensor is needed. Set up two measurements with the same setup;
change the Measurement Interval and the Averaging Time and use a different
Label for each. One would happen once a day (Measurement Interval 24 hours,
Averaging Time 24 hours), and the other once an hour (Measurement Interval 1
hour, Averaging Time 1 hour). It would be a good idea to set up the sampling
Interval to one minute for both sensors in order to save power (See page 70).
If two separate measurements are scheduled to measure the same sensor at the
same time (as they will in the examples above), only one reading of the sensor is
made and the result is shared by both measurements.
7.2. Telemetry Setup
7.2.1. Common Telemetry Setup
Regardless of the type of communication device installed in the X-Link, the
following telemetry settings are relevant.
Names and descriptions of each telemetry setup field are below. The
abbreviation Tx refers to transmission.
7.2.1.1. Tx Enable
Enables scheduled (sometimes called self-timed) transmissions. If this setting is
enabled, X-Link will periodically deliver sensor data to the designated
destination. If disabled, X-Link will not initiate any scheduled transmissions.
