Software functions
Password:
numerical code of max. 3 digits; 2 protection
levels of the programming data:
1st level Password “0”, no protection;
2nd level Password from 1 to 1000, all data are protected.
Transformer ratio
CT:
from 1 to 5000
VT:
from 1.0 to 199.9 and from 200 to 1999
Note: the CT * VT ratio must never exceed 5000. The current
measuring inputs are able to manage the CTs with secondary
of 1A and 5A (the accuracy is anyway always referred to 5A).
Display:
up to 2 variables/page.
