7.7.11.6.4 FieldCalStrain() Quarter-Bridge Zero
Continuing from FieldCalStrain() Quarter-Bridge Shunt Example (p. 231), keep the
249 kΩ resistor in place to simulate a strain. Using the CR1000KD
Keyboard/Display or software numeric monitor, change the value in variable
Zero_Mode to 1 to start the zero calibration as shown in figure Zero Procedure
Start
(p. 232). When Zero_Mode increments to 6, zero calibration is complete as
shown in figure Zero Procedure Finish
(p. 232).
