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 owing
through the meter, the energy direction arrow indicates which
quadrant is being used for the measurement, e.g.:
1st quadrant +P/+Q 3rd quadrant –P/–Q
2nd quadrant +P/+Q 4th quadrant +P/–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 bu󰀨ered in this instance
= Power reserve run-down, readout battery is empty or not
available. In this instance, the real time clock cannot be
bu󰀨ered.
3. The communication display lights up permanently when the data
interface (optical or electrical) and the meter are communicating. It
ashes on and o󰀨 when the parameterisation status is active.
4. The phase display indicates when individual phase voltages
are applied. All 3 symbols ash on and o󰀨 when the rotating eld
is wrong.
5. The unit shown matches the type of energy being measured or the
measured value displayed.
