5.1 Analog Inputs and Outputs
In order to operate the system without any interferences,
isolated BNC con-
nectors
are necessary. Otherwise there will be the danger of damages caused
by ESD or short circuits at the inputs. This will be the case when using not iso-
lated BNC T-pieces.
The
ADwin-Gold
device has to be connected to earth, in order to execute
measurement tasks without any interferences. Connect the GND plug via a
low-impedance solid-type cable with the central earth connection point of your
device.
The power supply from the power adapter at the computer also connects the
earth of the
ADwin-Gold
system with the earth of the computer. If you do not
operate the PC and the
ADwin-Gold
system in the same place, you should not
use the power supplied by the PC but an external power supply unit which is
earth-free, in order to avoid influences by different ground reference potentials.
In addition to the description of the inputs and outputs you will find notes below
for the conversion of digits into voltage values and for the input settings of the
analog inputs.
