The overall accuracy listed above is expressed as percentages of the full scale
value of this AI module.
The loads may be used either in a grounded or a floated state.
The shielding of the cables must be grounded either on the load side or the I/O
unit side.
The cable connected to each channel is one that is shielded either separately
from or together with the cables connected to the other channels.
This AI module can only be used with the station's number-of-points setting set
to 16.
If it is set to any other value (32 to 128), the module will not function.
The module supports only the value 16.
