2.1 External VT or CT ratio
Ct = External primary/secondary CT ratio
Ct = Selection in the field 1...9999
(max. primary current CT 50kA/5A – 10kA/1A)
Vt = External primary/secondary VT ratio
Vt = Selection in the field 1,00...10,00
For voltage direct connection (without external VT) load
By modifying the Ct and/or Vt ratios, the kWh meters are automatically
reset

Phase sequence diagnostic
In the software of the device we have added a specific functionality to detect and correct
many problems concerning voltage and / or current connection.
This function can be activated through password and allows to display and modify the
connection sequence provided that the following conditions are respected:
1) The neutral wire (in a 4-wire network) is connected to the right terminal
2) No crossings between cables connected to CT's
nals 1 and 3 - are connected some way both to CT1 and CT2)
3) The power factor is between 1 and 0,5 - Inductive load - for each phase.
