General
The measuring unit EKM 265 is designed for
checking
and
mea-
suring of
electrical
consumers in household and industry.
By
entering
a tariff (see B 3.1 tariff input) the operating
costs
for
the unit to be measured are calculated automatically and shown
in the
LC-display.
The measuring range of the EKM 265
is

-
2650W. As soon
as
these limits are exceeded, it
is

is
supplied by mains voltage and works without
batteries. Data saving for the tariffs

is
essential that you read the manual carefully before first
usage.
