7. METER
This function displays the basic measured quantities (AC) in the 3ϕ system. The display
format and legends (V, kV, A, kA, W, kW, MW, etc…) are automatically selected
appropriate to the measured values. The following quantities are displayed:
Phase r.m.s. voltage (U1, U2, U3).
Phase r.m.s. current (I1, I2, I3).
Per phase signed active, apparent and reactive powers (±P, ±S, ±Q).
Power Factors with indication of direction (capacitive or inductive).
Phase angle between voltage and current.
Phase to phase r.m.s. voltage (V1-2, V2-3, V3-1).
Total 3ϕ signed active, apparent and reactive powers. (±Pt, ±St, ±Qt)
Total 3ϕ Power Factor with indication of direction (capacitive or inductive).
System frequency.
Current in neutral conductor, r.m.s. value.

systems with a 3wire connection, the Instrument does not display values
for the 3rd phase. The central (TOTALS) line may then display two additional
messages:
seq? When three phase system is not connected in the correct phase
sequence (L1-L2-L3).
pow? When active power in one or more phase is negative.
Frequency will be displayed in inverse if the instrument is unable to find a valid
sync. input. The default sync. frequency (as defined elsewhere) is used.
