Z Measuring interval value
With an external power supply, the device operates in continuous measuring mode.
The measurement interval value is automatically set to the minimum value that is
technically possible.
Measuring interval value
The measuring interval is specified in the "Measuring interval value" parameter. This
option is recommended to optimize battery lifetime.
Enter the value for the measuring interval. Additional information: To increase
battery life, set as long an interval as possible. To optimize the measuring result, set
as short an interval as possible.
Intelligent adaptation
Under normal process conditions, the measuring device measures according to the
measuring interval specified in the "Measuring interval value" parameter. If the
process conditions change, the measuring device measures in shorter intervals
according to the usage rate specified in the "Energy budget intelligent adaption"
parameter. This option is recommended to optimize the measuring result.
To calculate the estimated battery life, use the Applicator →  95.
