Connecting Sensors And Transducers - Intab PC-Logger 3100i How To Use Manual

6.3 Connecting Sensors and Transducers

Sensors or Transducers are connected to the screw terminals that are
accessible under the lid.
The terminals are detachable and can be tilted 90°. Terminal assignment and
polarity can be seen in the figure below.
Use the 16 hole bracket as strain-relief for transducer cables. You can use a
tie-wrap or simply thread the wire trough two holes.
