13.7 Checking the power measurement
Short circuit all current transformer outputs
except for one and verify the powers displayed.
·The device may only display one power in the
phase with the current transformer output that
is not short circuited.
·If this is not the case, verify the connections
of the measured voltage and the measured
current.
If the value of the active power is correct, but the
sign is negative, this can have two causes:
1. Reversed connections S1(k) and S2(l) on the
current transformer, or
2. Active energy is being fed back into the
network.
Pull up the pointer diagram with details about the
power:

13.8 Checking the communication
The device counts all received (RX), all
transmitted (TX) and all faulty data packages.
Ideally, the number of faults shown in the Faults
column equals 0.
