7.3 Equipment Required
Precision equipment is a necessity
You will need precision equipment to accurately recalibrate these subsystems.
CAUTION Do not attempt recalibration without proper equipment and working knowledge of the
equipment.
The following table lists typical precision test equipment that can be used.
