Minimising Interference - Kipp & Zonen CT24 Instruction Manual

3.1

Minimising interference

To obtain maximum signal to noise ratio both before and after the
CT 24, it is advised to connect the CT 24 as described in this
chapter.
All Kipp & Zonen sensor cables have an internal shield that has to
be connected to the ground (housing) of the CT 24. For this
purpose pin 1 of the input connector strips can be used or one of
the screws that holds the PC board in place. Also the outgoing
cable must have an internal shield connected to the ground inside
the CT 24. For this purpose pin 1 of the output connector strips can
be used or one of the screws that holds the PC board in place.
If you don't want to connect the cable shields to the housing but
only interconnect with each other, use one of the interconnections
instead of pin 1. Make sure that the cable diameter is within the
size that the cable glands can hold (4 – 6.5 mm)
