Some strain-gage transducers with mV/V output include a "buffered shunt calibration"
feature. Connecting the transducer's Shunt Cal pin to its (-)Excitation pin, activates its
shunt calibration function. Transducers with this feature include:
• Model FP2000 pressure transducer with Options 2u and 3d
Figure 10-3: Transducer w/Buffered Shunt Cal Connection to Strain-Gage Input Channel
To use the transducer's buffered shunt cal feature, the instrument must be configured
to connect the SHUNT1 and SHUNT2 pins of the Input Channel connector when the
shunt cal feature is needed. If transducer and instrument were purchased together,
the instrument was configured for the correct Shunt Cal Application configuration.
