LC-displays
a) VDEW-display
1. The operation indicator shows the energy direction currently
measured by the meter (supply/drawing of active power, inductive/
capacitive reactive power). If there is a consumer current owing,
the energy direction arrows show in which quadrant the value is
measured. E.g.:
1. quadrant +P/+Q 3. quadrant –P/–Q
2. quadrant –P/+Q 4. quadrant +P/–Q
2. The battery status display shows the remaining capacity of the
read-out battery resp. of the power reserve of the real-time clock.
= Full voltage, in this case the real-time clock is buered.
= Power reserve exhausted and no read-out battery present,
buering of the real-time clock not possible.
3. The communication indicator lights continuously when there
is communication with the meter via the data interface (optical or
electrical). The indicator ashes if the parametrisation status is
active.
4. The phase indicator signalises the connection with the individual
phase voltages. In case of wrong phase sequence all 3 symbols
ash.
5. The unit is indicated corresponding to the measured energy type or
the displayed measured value.
