Once the Logging Interval (Sample Period) is entered the Averaging Sub Interval will be updated. If you want to use a different Averaging Sub Interval to the one automatically set by the system, enter the value after the Logging Interval (Sample period) has been set and before you click on the "Start Logger" button.
The Omnilog software determines if the logger has a user adjustable Averaging Sub Interval and displays a box to enter a new Average Sub Interval. If the logger does not support Averaging Sub Interval the box will be hidden.
When the Averaging Sub Interval is set to 1 second and the logger takes readings every second this becomes a significant draw on the loggers battery. The loggers have been designed to run for 5 years on a battery, under ideal circumstances, but an Averaging Interval of one second will drain the battery in just over a year on some of our loggers. see Battery Life
So it is not recommened to run HR series loggers with a Firmware Version of 3.x or less in Average, Maximum or Minimum mode for long periods of time. (You can, but it will shorten the life of the battery).
If you are running GP-MC or HR series loggers (Firmware ver 4.x or greater) for long periods, we suggest setting the Averaging Sub Interval to 10 seconds or greater.
If the GP-MC is running on an external power supply, then the Averaging Sub Interval can be set to any value as there will no battery drain problem.
