Analogue Signal Transmitter AST 3
1
Introduction
AST 3 is a high performance transmitter, designed for industrial measuring
by means of strain gauge transducers. The compact module is easily
installed on a DIN rail or a flat surface.
Two slightly different versions of the transmitter module are available:
AST 3B, designed for operation together with a control unit.
Instructions for installation and set-up are found on a diskette,
delivered with the transmitter module.
AST 3P, with display window and function keys for set-up and
measuring operations.
This instruction includes the basic installation and set-up, required for correct
measuring with the instrument.
Additional installation and set-up of more instrument functions, not covered by
this description, can also be performed.
For a complete instrument description, refer to publication 600 232:
