7.6.2.1. PEAK ENERGY DEMAND
In three-phase systems, by selecting the POWER function and pressing F1 thrice you can
reach the “Peak Demand” mode. This mode shows the values corresponding to the
recording being performed or to the last performed recording (if no recording is being
performed).
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
with reference to the integration period set for the recording. This screen also shows the
corresponding active energy and the corresponding peak date and time.

Exampl
e of “PEAK ENERGY DEMAND” screen
 F1:
to display the previous or the following screen. On the basis of the
settings made as per paragraph 7.1 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 and the
instantaneous values of voltage and current present at the instrument
inputs. This function is disabled during a recording
 ENTER/HOLD: to enable/disable the HOLD function (updating interruption) of
displayed data. All previous functions remain however available. When
the HOLD function is activated, the word
HOLD is displayed. When
this function is enabled it’s not possible to record nor perform energy
measurements. This function is disabled during a recording or an
energy measurement
 MENU: to enter the MENU mode and change the instrument settings (see
paragraph 7.1 and 7.2
). 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
