Meta
Meta measurements use the result of another measurement as their basis. Usually,
a Meta measurement is used to average results of another measurement.
Meta Index
This setting tells MONITOR what other measurement this Meta measurement
refers to.
Why use meta measurements? If one had setup an hourly averaged temperature
measurement, a Meta measurement could be setup 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, MONITOR will try to delay the meta measurement
until the reference completes.
Soil
Soil measurements are used with specific soil moisture/conductivity sensors
available from Sutron. Two sensors are available: soil moisture and soil
conductivity. Both sensors can additionally measure soil temperature.
Soil Type
This setting tells MONITOR what kind of soil sensor is connected and what
measurement to make. The choices:
Moisture
Conductivity
Temperature
A moisture sensor can measure moisture and temperature – it cannot measure
conductivity. Likewise, a conductivity sensor cannot measure moisture. Both
sensors can measure soil temperature.
Each soil sensor uses one 0-5V analog input. When setting up the sensor, choose
either 0-5V A or 0-5V B as the analog input, depending on what connector the
