These resistor locations connect the high side to the low side of the
corresponding channels, thereby acting as shunts. If, for example,
you add a 250
Ω
resistor to location R17, and connect a 4 to 20 mA
current loop input to channel 0, the input range is converted to 1 to
5 V. Note that, depending on your application, you may need to use
resistors R1 to R16 with resistors R17 to R32 for proper operation.
Refer to
page 74 for an example of using current shunt resistors.
