Introduction
WST 3 is a high performance transmitter, designed for industrial measuring
by means of strain gauge transducers. It can be used as a slave unit,
communicating with a network master/PLC by Modbus or Profibus.
The network can be used for transmission of commands and measurement
values and also for set-up of the transmitter.
The compact transmitter is easy to install on a DIN rail or a flat surface.
This instruction includes the basic installation and quick set-up, required for
correct measurement with the transmitter.
Additional installation and set-up of more functions, not covered by this
description, can also be performed.
For a complete transmitter description, refer to publication 600 630:
