1. Read first and then ...
The proper and safe operation of the device
assumes that the Operating Instructions is
read carefully and the safety warnings given
in the various Sections
4. Mounting
5. Electrical connections
6. Adjustable measuring range
by DC calibration
are observed.
The device should only be handled by appropriately
trained personnel who are familiar with it and authorised
to work in electrical installations.

2. Brief description

The SINEAX U 553 measuring transducer is used to convert
a sine-wave or distorted AC voltage.
The output signal, in the form of a load independent DC
current or voltage, is proportional to the measured value.
