6.3.2.1. Peak energy demand
In three-phase systems, by selecting POWER and pressing F1 key thrice you can reach
the “Peak Demand” mode. This mode shows the values corresponding to the running
recording or to last performed recording (if any recording is running).
The “
Peak Demand ” screen shows the Max Average value of Active Power (and the
corresponding Energy) or Max Average value of Apparent Power (and the corresponding
Energy) measured during the last (or running) recording. The Average value is evaluated
in the Integration Period set for the recording. This screen also shows the corresponding
Active Energy and the corresponding Peak Date and Time.

Examples of “PEAK ENERGY DEMAND” screen
The symbols used are described in Tab. 3. For eventual messages displayed see chapter
14. Following keys are enabled:
•
F1 : to display the previous or the following screen. On the basis of the
settings made as per paragraph 5.2 following screens are displayed
cyclically:
•
Three-phase 3-wire: total three-phase values, Wattmeter phases 1-2 and 2-3 values, Peak Demand
•
Three-phase 4-wire: total three-phase values, phase1, phase2 and phase3 values, Peak Demand
•
F3 : to show Active Power and Active Energy values
•
F4 : to show Apparent Power and Apparent Energy values
•
SAVE : to save in the instrument memory a record of “Smp” type (see
paragraph 5.4) and the instantaneous values of voltage and current
present on the instrument inputs. This function is disabled during a
recording.
•
ENTER/HOLD : to enable/disable the HOLD function (updating interruption) of the
displayed data. All the previous functions remain however available.
When the HOLD function is enabled, the word
HOLD is displayed.
When this function is enabled it’s not possible to record or take an
energy measurement. This function is disabled during a recording or
an energy measurement.
•
MENU : to enter the MENU mode and change the instrument settings (see
paragraph 5.2 and 5.3). It’s not possible to enter the configuration
MENU during a recording or an energy measurement.
•
START/STOP : to record selected parameters according to the instrument’s settings
(see chapter 7).
