period equal to one quarter of the maximum learning duration, learning is
complete; otherwise, the learning period will be the maximum learning duration.
Example: Setpoint learning duration in a stable system
In this example, the learning duration is 30 days. When the system is stable for 7.5
days (one quarter of 30 days) learning is complete.

Implementing standard alarm setpoint learning using ION Setup
You can use ION Setup to implement setpoint learning, which analyzes your
power system and recommends settings.
NOTE: Your meter’s power system must be stable in order to learn valid
setpoint values.
1. Start ION Setup.
2. Open the Setup Assistant for your meter.
3. Navigate to Alarming > Standard .
NOTE: You can manually configure setpoint values by selecting the
setpoint and clicking Edit .
