Memory functions
11.3 Long-term memory
The multimess F144-2-LED-ESMS-...-4 supports the long-term memory func-
tionality described in the following section.
11.4
Load profi le memory
The measuring device has a load profi le memory that can record a maximum
of up to 35136 entries depending on the number of parameters to be stored
(active power periods for HT and LT, consumption and recovery, reactive power
periods for HT and LT, capacitive and inductive) and the measurement period
selected by the user (period values of 60 / 30 / 15 / 1 minute(s) are possible).
This means that a period of 15 minutes results in a maximum storage duration
of 365 days.
The measurement period and the selection of the parameters to be saved can
be parameterized using a computer with the optionally available software.
NOTE
Setting the internal clock:
If the time of the multimess F144-2-LED-ESMS-...-4 is set to less than the dura-
tion of one period, the measurement for the instantaneous period is fi nished
and saved the next time the device synchronizes.
If the time of the multimess F144-2-LED-ESMS-...-4 is adjusted by more than the
period time, the load profi le memory is deleted and restarted.
In both cases, a clock adjustment event is created and saved in the event
memory. Adjusting the period time:
If the period time is adjusted, the load profi le memory is deleted and restarted.
An adjustment event (adjustment of the parameters) is created and entered in
the event memory.
