Three wire measurement (Option)
The UMG503 is suited for measurement in networks
with or without neutral conductor. Networks with a neu-
tral conductor are called four wire networks, without
neutral conductor are called three wire networks.
The option "three wire measurement" is needed for the
connection examples 5 and 6.
When option "three wire measurement" is released, you
can select between three wire measurement "3L" and
four wire measurement "4L" in menu CONF.
Select
In menu CONF you
move to the indication
of three or four wire
measurement using key
3.
In this example the four
wire measurement "4L"
is activated.
Change
With key 1 can be
switched between four
wire (4 L) and three
wire measurement (3
L).

Attention!
In networks without neutral conductor voltage
transformers must be used!
