The shunt calibration resistor can be installed on the Full Range Digital
Universal Conditioner module, or, in the transducer ID module. R33
assigns a positive or negative excitation to the shunt calibration resistor
if installed on the Full Range Digital Universal Conditioner module (not
the transducer ID module).
Jumper W8 connects -EX to ground for situations requiring single-
ended excitation.
–EX = –EX
–EX = GND
Default
R32 changes the offset of the bridge balance circuit. If the zero offset is
too large when the sensor bridge is balanced, you should add an
appropriately sized resistor.
