ET LOGGINGINTERVAL
SET LOGGINGINTERVAL
When automatic logging is active, the tag will retrieve a value from the sensor
and store it in tag memory on a periodic basis until the memory is full. At this
point logging will cease. The periodicity of this logging is controlled by the logging
interval parameter. This parameter is defined in terms of hours:mins:secs and
defines the period between sensor logs.
Note: The minimum allowable logging interval is 1 minute.
Note: The tag will sleep while not in use, and then will wake up to take a sensor
reading and then sleep again. This mode of operation ensures a long battery life.
The logging interval command takes three parameters, each separated by a
colon, in the form hh:mm:ss.
