1. Check the
operating display is
shown. A flashing
'FF' shows fatal
errors.
2. Check phases L1,
L2, and L3 are
present and in the
correct phase
sequence, i.e. L1-
L2-L3.
If one phase is not present or the voltage is < 45% Un, the relevant
symbol is absent. With the normal phase sequence the symbols are
displayed continuously.
If the meter is connected with reversed phase sequence (e.g. L2-L1-
L3) the symbols flash.
3. The energy flow
arrows indicate
whether energy is
being imported (+)
or exported (-).
P = active energy,
Q = reactive
energy.
