This guide describes how to install and use the SCXI-1321 offset-null
and shunt-calibration terminal block with your SCXI-1121 module.
You can only use the SCXI-1321 terminal block with SCXI-1121 revision
C and later revisions. The SCXI-1321 terminal block has a shielded board
with supports for connection to the SCXI-1121 input connector. In addition
to the 18 screw terminals, the SCXI-1321 has circuitry for offset-null
adjustment of Wheatstone bridges, and a shunt resistor for strain-gauge
shunt calibration. This terminal block was primarily designed for
bridge-type transducers such as strain gauges. The SCXI-1321 can also
easily accommodate thermocouples, RTDs, thermistors, millivolt sources,
volt sources, and current-loop receivers.
To set up and use your SCXI-1321, you will need the following items:
SCXI-1321 offset-null and shunt-calibration terminal block
SCXI-1321 Offset-Null and Shunt-Calibration Terminal Block
