Digital Universal Conditioner (DUC) Bridge Connections
The following figures show the full-, half-, and quarter-bridge configurations
for a DUC that is configured as a DC conditioner.
Shunt calibration The shunt-calibration resistor (R Shunt) sockets are located on the front of
the I/O carrier board. Use system hardware-mapping software to specify
which leg of the bridge is shunted during calibration.
Note If you use MTS TEDS modules or MTS transducers with integrated
shunt-calibration resistors, you must insert a jumper plug (MTS part
number 100-188-097) into the socket for each transducer input
where you will use the integrated shunt-calibration resistor.
