The symbols used are described in Tab. 4. For eventual messages displayed see chapter
14. Following keys are enabled:
•
F2 : to start / stop immediately a direct energy measurement . The energy
counters will start increasing proportionally to the active power
absorbed by the load.
The results obtained cannot be memorized.
If the active power is negative the counters will not increase.
•
F1 : (only for 4-wire measurement) to display the following screen. On the
basis of the settings made as per paragraph 5.2 following screens are
displayed cyclically:
Overall three-phase values, values of phase 1, phase 2 and phase 3
•
SAVE : to save in the instrument memory a record of “Smp” type (see
paragraph 5.4) containing 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).
