12:03 Sample sensor (reading = 3.0). There are not enough samples to produce an average.
System will still compute and log a result producing a value of 2.0;
12:04 Sample sensor (reading = 4.0). There are not enough samples to produce an average.
System will still compute and log a result producing a value of 2.5;
12:05 Sample sensor (reading = 5.0). Compute and log 5-minute average. Result = 3.0, computed
as (1.0+2.0+3.0+4.0+5.0)/5;
12:06 Sample sensor (reading = 6.0). Compute and log 5-minute average. Result = 4.0, computed
as (2.0+3.0+4.0+5.0+6.0)/5;
12:07 Sample sensor (reading = 7.0). Compute and log 5-minute average. Result = 5.0, computed
as (3.0+4.0+5.0+6.0+7.0)/5;
Compare this to a simple average. A simple average over five minutes would produce a reading every five
minutes. It would be setup with Measurement Interval of five minutes, an Averaging Time of five minutes,
and a Sampling Interval of 60 seconds.
12:01 Sample sensor (reading = 1.0). No reading is logged.
12:02 Sample sensor (reading = 2.0). No reading is logged.
12:03 Sample sensor (reading = 3.0). No reading is logged.
12:04 Sample sensor (reading = 4.0). No reading is logged.
12:05 Sample sensor (reading = 5.0). Compute and log 5-minute average. Result = 3.0, computed
as (1.0+2.0+3.0+4.0+5.0)/5;
12:06 Sample sensor (reading = 6.0). No reading is logged.
12:07 Sample sensor (reading = 7.0). No reading is logged.
A Result of Running Min and Running Max produce results which are the minimum and maximum of the
Running Average during the interval. Just like the simple minimum and maximum, running minimum and
maximum values are logged with the time stamp of when the minimum and maximum occurred rather
than when the measurement was scheduled.
The system holds up to 180 samples for the Running Average. How many samples are to be used is
computed by dividing the Averaging Time with the Sampling Interval. If the setup is such that more than
180 samples are required, the system will show a setup error:
Setup Errors: M1 Too many samples setup for running average
Additionally, every time a measurement is completed without all the samples, the system will log a
“Missing samples” error.
Logging and Transmitting Minimum and Maximum
The time for the average will be computed based on the measurement time and interval, as described
previously. However, the time stamp for the minimum and maximum will be the actual time when the
minimum or maximum occurred. For example, you may see the following in the log for an hourly average
with samples every minute where the data is not in time sequence:
4/14/2016 16:00:00 AVG 30.335 G
4/14/2016 15:24:00 MX 31.248 G
4/14/2016 15:15:00 MN 25.661 G
4/14/2016 17:00:00 AVG 30.225 G
