6.3.2.1. PEAK ENERGY DEMAND 
In three-phase system selecting the POWER Position and pressing F1 key 3 times you 
can reach the “Peak Demand” mode. 
T
he “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.

Example of “PEAK ENERGY DEMAND” screen
 
 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 wires: total three-phase values, Wattmeter phases 1-2 and 2-3 values,
Peak Demand
 Three-phase 4 wires: 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 in 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).
