The phase voltage indications are switched on, if the respective phase
voltages are present. It can be selected by parameterisation whether all
the phase voltage indications are flashing, if the rotating field goes in the
wrong direction, and/or whether they are flashing, if the energy flow is
reversed in the corresponding phase. The meter can also be configured
so that it will flash in service mode only.
The significance of the two segments A and B (a diamond and a circle)
is to show that both the kVArh (diamond) (reactive measurement is an
option) and the kWh (circle) registers have entered anti-creep mode.
Zero energy is flowing through the meter, which is further illustrated by
the lack of any energy direction indicator.
Example A (OBIS code 1.8.1)
A B
To introduce the function of the direction indicators, we move to the
display below (example B). The Reactive Register is still in anti-creep
mode (diamond symbol and lack of reactive direction indicators).
The Active Register is, however, now measuring energy. The circle
symbol is no longer lit and we have direction indicators +P and –P. The
+P indicator is solid 'on', which indicates that the instantaneous active
energy is predominantly in a positive direction (phases summed). The
–P indicator is flashing, which indicates that there is an amount of
reverse energy being measured, but it is less than the forward energy.
Example B (OBIS code 1.8.1)
