10.0 WARRANTY REPAIR POLICY 
Limited Warranty on Products 
Any Cooper Instruments product which, under normal operating conditions, proves defective in material 
or in workmanship within one year of the date of shipment by Cooper will be repaired or replaced free of 
charge provided that a return material authorization is obtained from Cooper and the defective product is 
sent, transportation charges prepaid, with notice of the defect, and it is established that the product has 
been properly installed, maintained, and operated within the limits of rated and normal usage. 
Replacement or repaired product will be shipped F.O.B. from our plant. The terms of this warranty do not 
extend to any product or part thereof which, under normal usage, has an inherently shorter useful life than 
one year. The replacement warranty detailed here is the buyer’s exclusive remedy, and will satisfy all 
obligations of Cooper whether based on contract, negligence, or otherwise. Cooper is not responsible for 
any incidental or consequential loss or damage which might result from a failure of any and all other 
warranties, express or implied, including implied warranty of merchantability or fitness for particular 
purpose. Any unauthorized disassembly or attempt to repair voids this warranty. 
Obtaining Service under Warranty 
Advance authorization is required prior to the return to Cooper Instruments. Before returning the item, 
contact the Repair Department c/o Cooper Instruments at (540) 349-4746 for a Return Material 
Authorization number. Shipment to Cooper shall be at buyer’s expense and repaired or replacement 
items will be shipped F.O.B. from our plant in Warrenton, Virginia. Non-verified problems or defects may 
be subject to a $150 evaluation charge. Please return the original calibration data with the unit. 
Repair Warranty 
All repairs of Cooper products are warranted for a period of 90 days from date of shipment. This warranty 
applies only to those items that were found defective and repaired; it does not apply to products in which 
no defect was found and returned as is or merely recalibrated. It may be possible for out-of-warranty 
products to be returned to the exact original specifications or dimensions. 
* Technical description of the defect: In order to properly repair a product, it is absolutely necessary for 
Cooper to receive information specifying the reason the product is being returned. Specific test data, 
written observations on the failure and the specific corrective action you require are needed.
