7.8.1.6.2 Quarter-Bridge Zero (Option 10)
Continuing from Quarter-Bridge Shunt (Option 13)
(p. 165),
keep the 249-kΩ
resistor in place to simulate a strain. Using the external keyboard / display or
software numeric monitor, change the value in variable Zero_Mode to 1 to start
the zero calibration as shown in figure Starting Zero Procedure (p. 166). When
Zero_Mode increments to 6, zero calibration is complete as shown in figure Zero
Procedure Finished
(p. 167).
