The accumulation time is indicated at the top of the measurement display.
A further press of 21 gives a detailed view of the individual phase values.
Capacitor or inductance symbols issue information about capacitive or
inductive reactive power.
Hold/Run functionality is explained earlier in this manual.
Note
In the individual representation of A or B or C, the active and
reactive energy cannot be selected.
Three-Phase Power Theory
By switching the Power Network setting from wye to delta, the voltages and
currents I
L1
, I
L3
, I
L2
are calculated, measured and displayed.
When calculating the power, selecting the delta connection will use the two-
wattmeter method (Blondel or Aron) measuring circuit for the calculation.
The neutral conductor may be connected; however, it does not influence the
measurement even in open state. If no neutral conductor is connected, a virtual
“metering neutral” is established in the Logger via symmetrization resistors.
