What is the default energy rollover value for ION meters?

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

Product Line
ION meters

Environment
Energy Calculations

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.

Meter Name	Default Rollover Value	Maximum Energy Value
ACM3710	0	999,999,999
ACM3720	0	999,999,999
ION6200	10,000,000	999,999,999
ION6300	0	999,999,999
ION7300	10,000,000	999,999,999
ION7330	10,000,000	999,999,999
ION7350	10,000,000	999,999,999
ION7500		999,999,999
ION7550	10,000,000	999,999,999
ION7600		999,999,999
ION7650	10,000,000	999,999,999
ION7700	0	999,999,999
ION8300	0	999,999,999
ION8400	0	999,999,999
ION8500	0	999,999,999
ION8600	10,000,000	999,999,999
ION8650	10,000,000	999,999,999
ION8800	0	999,999,999
PM8000	10,000,000	999,999,999
ION9000	10,000,000	999,999,999

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.
