Connecting half bridges requires the NI 9986.
■
The NI 9218 provides 2 V excitation to half bridges of ≥240 Ω total or 3.3 V
excitation to half bridges of ≥700 Ω total.
■
The NI 9218 provides optional connections for remote sensing (RS) and
shunt calibration (SC). Remote sensing corrects for errors in excitation leads
and shunt calibration corrects for errors caused by resistance within one leg of
the bridge.
