 3. Nose Landing Gear Load Sensor Installation
__________________________________________
 A. General
 (1)  After the installation of a load sensor you must adjust the sensor zero. There are two zero adjustment procedures. It is necessary to do only one of the two adjustment procedures. One procedure does not require the airplane to be on jacks. The other procedure requires the airplane to be on jacks. Both procedures use the keyboard modes of the weight and balance computer (WBC).
 (a)  
After sensor installation, do the automatic zero adjustment (without jacks, mode 38) if you replaced only one sensor on the nose landing gear.

 (b)  
After sensor installation, do the zero adjustment on jacks (mode 99) if you replaced two or more sensors on the nose landing gear.
