The NI 435x accessories—the TBX-68T, CB-68T, and TBX-68 for the
NI 435x for USB, PXI, and PCI—are designed to be used with RTDs,
thermistors, and resistors. Consult the accessory installation guide for
instructions on how to connect the resistors. Figures 2-10 and 2-11 show
examples of how to use different transducers connected to analog channels
in the same measurement setup.
