Issue
A user would like to know the default rollover values of the various ION meters.

Cause
A user would like to know the default rollover values of the various ION meters.
Resolution
Below is a list of ION meters and their default rollover values:
NOTE: By default, some of the meters have a Default Rollover Value of 0. This disables the rollover feature. In this case the meter will continue to accumulate energy until it hits the Maximum Energy Value.
To avoid losing any resolution of the energy accumulate value it is recommend that the roll-over be set to 10 000 000. 16777215 (=2^24-1) is the absolute limit imposed by the 32bit IEEE register format without loss of resolution on the stored number.
NOTE: For instructions on how to change the rollover values on ION meters, please refer to: FA209519
