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

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

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.
