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
•
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
