Oversampling

The oversampling feature enables you to increase the precision of a data sample collected at a
scheduled reading by reading multiple samples. You can specify the number of samples that should be
read and the time interval between each reading. You can also specify how the data samples should
be manipulated to create the final data sample that is pushed: an average value of all of the samples,
the minimum value, or the maximum.
Oversampling can be enabled on all four Analog 4-20mA Current Loop and on all four Analog Voltage
inputs.
For example, oversampling is configured to discover the average value of 10 readings taken 70
milliseconds apart. Whenever Digi Connect Sensor+ needs a value for that sensor, such as on a
scheduled wake, it actually reads the sensor 10 times, 70 milliseconds apart, averages those results,
and uses the averaged value as the sensor reading.
Note Reading a large number of data samples over a long interval reduces battery life.
