LC display
1. The
operation display
shows the energy direction that is currently
being measured by the meter (supply/draw of active power,
inductive/capacitive reactive power). If a load current is flowing
through the meter, the energy direction arrow indicates which
quadrant is being used for the measurement, e.g.:
1st quP/+Q
3rd quadrant –P/–Q
2nd quP/+Q
4th quP/–Q
2. The
battery status indicator
shows the residual capacity of the
readout battery or the internal power reserve of the real time clock.
=
Full power, the real time clock is buffered in this instance
= Power reserve run-down, readout battery is empty or not
available. In this instance, the real time clock cannot be
buffered.
3. The
communication display
lights up permanently when the data
interface (optical or electrical) and the meter are communicating. It
flashes on and off when the parameterisation status is active.
4. The
phase display
indicates when individual phase voltages
are applied. All 3 symbols flash on and off when the rotating field
is wrong.
5. The
unit
shown matches the type of energy being measured or the
measured value displayed.
