UMG 96RM-E
Current measurement via I1 to I4
The UMG 96 RM-E is designed to have current
transformers with secondary currents from ../1A
and ../5A attached cia terminals I1-I4. The factory
default for the current transformer ratio is 5/5A and must
be adapted to the current transformer employed
if necessary.
Direct measurement without a current transformer is not
possible using the UMG 96RM-E.
Only AC currents can be measured - DC currents
cannot.
Via the current measurement input I4 only an apparent
current measurement is carried out thanks to the lack
of a multiplier. Power measurements are therefore not
possible using the I4 input.
c
Caution!
The current measurement inputs are
dangerous to touch.

The attached screw terminal has to be
fixed sufficiently with two screws on the
device!
c
Caution!
The test leads must be designed for an
operating temperature of at least 80°C.
