Setting Resistance
Baseline for Excitation
Monitor 1. C2 Load Cells
If C2 load cells are used in the weight control system, the controller
calculates the resistance value during power up and turns on the excita-
tion monitor.
2. Non C2 Load Cells
If Non C2 Load Cells are used in the weight control system, the con-
troller will capture the resistance value when performing the Hard Cal-
ibration when setting the Zero Calibration Value.
