Three-Phase Power Theory - Fluke 1735 User Manual

The accumulation time is indicated at the top of the measurement display.
A further press of 21 gives a detail view of the individual phase values.
Capacitor or inductance symbols issue information about capacitive or
inductive reactive power.
With Hold/Run the values displayed at the moment "freeze" and the
measurement is stopped or started again.
In the individual representation of A or B or C, the active and
reactive energy cannot be selected.

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.
