This guide describes how to install and use the SCXI-1321 offset-null
and shunt-calibration terminal block with the SCXI-1121 module. You can
only use the SCXI-1321 terminal block with SCXI-1121 revision C or later
modules. In addition to the 18 screw terminals, the SCXI-1321 has circuitry
for offset-null adjustment of Wheatstone bridges, and a socketed shunt
resistor for strain-gauge shunt calibration. This terminal block was
primarily designed for Wheatstone bridge transducers such as strain
gauges, although it can easily accommodate thermocouples, RTDs,
thermistors, millivolt sources, volt sources, and current-loop receivers.
Thermocouples have cold-junction compensation (CJC) support.
