Mitsubishi Electric AE-200A Instruction Book page 8

The following shows an operation example of the apportioned electricity billing function of the AE-200 (when it is
started at 10:00).
The example assumes that there are no apportioned results in the past (at the default settings) and that 180000
(1800 seconds = 30 minutes) is set in the "Log_interval" property.
The time when the apportioned result is stored for the first time is indicated by bold characters.
