Platinum Stock Products

 

– Lifetime Warranty Plus. Under PCB’s Lifetime Warranty Plus, if any 

PCB Platinum Stock Product ever fails, PCB will repair, replace or exchange the product at no charge. 
As a further benefit under PCB’s Lifetime Warranty Plus, PCB will, for a one (1) year period following 
the delivery date of any PCB Platinum Stock product, refund 100% of the customer's purchase price 
paid for any such Product with which the original purchaser is not completely satisfied. This option of a 
refund may be selected in lieu of the repair, replacement or exchange of the product. “Platinum Stock 
Product” is defined as any PCB Stock Product designated by PCB from time-to-time as a “Platinum” 
model.  

 
C. Stock Products

 

– Limited Warranty. PCB warrants that all PCB Stock Products will be free from 

defects in materials and workmanship for a period of two (2) years from the date of original purchase. If 
any Stock Product shall fail during the warranty period, PCB will repair, replace or exchange it without 
charge. As a further benefit under PCB’s Limited Warranty for Stock Products, PCB will, for a (1) year 
period following the delivery date of any PCB Stock Product, refund 100% of the customer's purchase 
price for any PCB Stock Product with which the original purchaser is not completely satisfied. “Stock 
Product” is defined to mean any product designated by PCB from time-to-time as a “Stock Product”. 
This is generally a product on which PCB customarily maintains finished goods inventory. 

 
D. Standard Products, Special Products and Test and Measurement Cables

 

– Limited Warranty. 

PCB warrants that all PCB Standards, PCB Specials and test and measurement cables will be free 
from defects in materials and workmanship for a period of one (1) year from the date of original 
purchase. If any PCB Standard or PCB Special shall fail during the warranty period, PCB will repair, 
replace or exchange it without charge. “PCB Standard” is a product regularly manufactured by PCB for 
which PCB does not customarily maintain finished goods inventory. “PCB Special” is defined as any 
customized or modified PCB product for which PCB does not customarily maintain finished goods 
inventory, or any other product PCB classifies as a special from time to time. 
 

Service 

Because of the sophisticated nature of PCB instrumentation, field repair is typically not recommended 
and may void any warranty. If factory service is required, return the instrumentation according to the 
"Return Procedure" stated below. A repair and/or replacement quotation will be provided prior to 
servicing at no charge. Before returning the unit, please consult a factory PCB applications engineer 
concerning the situation because certain problems can often be corrected with simple on-site 
procedures.
