Selecting one of the sensors listed at the
‘
SnSr
’ menu entry, will configure the sen
-
sor parameters to the values indicated in
the table.
The table also indicates the typical con
-
nections for each type of sensor. Param
-
eters can be manually modified.
Connections are indicated for a single sen
-
sor connected to the channel A. For two
sensors (for inhibition control, quadrature
signal, etc) apply the same connection cri
-
teria also to channel B.
Note : indicated values are typical values.
Check the correct specifications with your
sensor datasheet and adapt the required
configuration and connections as needed.
