Electronic System Control Validation
Once programming software has been completed per original SOW and basic function testing has been performed by North American Hydraulics Inc., this initial release has must be validated on the machine. The customer is responsible for complete functional and dynamic testing of the program and final validation on the machine. The customer will provide a NAHI technician with the capability to monitor software and or download software. Future software changes can be requested using a SOW addendum. The customer understands that all programming changes require machine validation and that additional engineering charges may apply.
