5.0 Maintenance and Repair
Because of the sophisticated nature of PCB instrumentation, field repair of the equipment is not recommended. Most
PCB signal conditioners are of modular construction and are factory repairable. A repair or replacement quotation is
available at no charge. Before returning equipment for repair, it is advisable that the user confers with a factory
application engineer (or international representative) concerning the difficulty to ascertain if an on-site procedure
rectifies the problem.
If repair is indicated, contact PCB to request a Return Materials Authorization (RMA) number from the factory. An
advanced authorization to proceed with the repair, permitting charges of up to 50% of a new item, greatly expedites
repair.
For the most efficient service, please provide a detailed, written description of the malfunction encountered with the
equipment you are returning, together with your specific application and setup procedures. International customers
should return PCB equipment to their representative. For exceptions, please contact the International Sales department at
PCB to request shipping instructions and an RMA.
