General Information
Introduction
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
The UMT 1 is a measuring transducer for true RMS values. The UMT 1 can measure an electrical three-phase
system with current and voltage measuring inputs. The primary measured values are calculated and displayed on
the two-line, 16 character LC Display, and also transmitted by either analog outputs (configurable as -20 to
20 mA, 0 to 20 mA, or 4 to 20 mA) or a communication interface to a higher level-control system. Different
packages offer additional functionality.
The detailed model description for the UMT 1 reads as follows:
UMT1 1 5 -h0000 B/
ABDEF..Z
Options according to list of options

Intended Use
The unit must only be operated in the manner described by this manual. The prerequisite for a
proper and safe operation of the product is correct transportation, storage, and installation as well as careful oper-
ation and maintenance.
NOTE
This manual has been developed for a unit fitted with all available options. Inputs/outputs, functions,
configuration screens, and other details described, which do not exist on your unit, may be ignored.
The present manual has been prepared to enable the installation and commissioning of the unit. Due
to the large variety of parameter settings, it is not possible to cover every combination. The manual is
therefore only a guide. In case of incorrect entries or a total loss of functions, the default settings may
be taken from the list of parameters enclosed at the rear of this manual.
