Sutron Corporation Satlink Operations & Maintenance Manual, Rev 8.04.2 11/3/2016 pg. 87
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,
Satlink will try to delay the meta measurement until the reference completes.
9.3.9. Measure Type: Manual Entry
Manual entry measurement types allow the user to enter a reading manually. That value
becomes the reading of the measurement. Satlink will store the user entered value in the Offset
field.
To enter a manual entry reading, use LinkComm's Calibrate button.
9.3.10. Measure Type: Internal Temperature
Internal Temperature measurements use a temperature sensor installed inside Satlink. Every
Satlink 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.
9.4. Processing Settings
9.4.1. Slope
See Offset below.
9.4.2. Offset
Every measurement is computed by taking the sensor reading, multiplying it by slope and adding
offset to it.
Measurement result = (sensor output)*slope + offset
Slope defaults to 1.0 and offset defaults to 0.0, meaning they will not affect measurement result
by default.
Traditionally, when using an analog sensor, slope and offset are required to convert the voltage
output by the sensor into desired units. The required slope and offset are provided by the sensor
manufacturer.
Satlink supports more complex equation processing (see Equations below).
Slope and offset are applied after equations.
The reading before slope and offset are applied is referred to as the raw reading. For example, if
an analog sensor were to provide a voltage of 2 volts, and the user had set up the Slope as 5 and
