Following keys are active:
 F2:
to pass to "WAVE" mode (see paragraph 7.6.3).
 F1:
(only for three-phase measurement) 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/F4:
to pass to previous/next function respectively
 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
