All product names are trademarks of their respective companies. 87V MAX Digital Multimeter Users Manual Lifetime Limited Warranty Each fluke 20, 70, 80, 170, 180 and 280 Series DMM will be free from defects in material and workmanship for its lifetime. As used herein, lifetime is defined as seven years after fluke discontinues manufacturing the product, but the warranty period shall be at least ten years from the date of purchase. This warranty does not cover fuses, disposable batteries, damage from neglect, misuse, contamination, alteration, accident or abnormal conditions of operation or handling, including failures caused by use outside of the product s specifications, or normal wear and tear of mechanical components.

2 This warranty covers the original purchaser only and is not transferable. For ten years from the date of purchase, this warranty also covers the LCD. Thereafter, for the lifetime of the DMM, fluke will replace the LCD for a fee based on then current component acquisition costs. To establish original ownership and prove date of purchase, please complete and return the registration card accompanying the product, or register your product on fluke will, at its option, repair at no charge, replace or refund the purchase price of a defective product purchased through a fluke authorized sales outlet and at the applicable international price. fluke reserves the right to charge for importation costs of repair/replacement parts if the product purchased in one country is sent for repair elsewhere. If the product is defective, contact your nearest fluke authorized service center to obtain return authorization information, then send the product to that service center, with a description of the difficulty, postage and insurance prepaid (FOB Destination).

3 fluke assumes no risk for damage in transit. fluke will pay return transportation for product repaired or replaced in-warranty. Before making any non-warranty repair, fluke will estimate cost and obtain authorization, then invoice you for repair and return transportation. THIS WARRANTY IS YOUR ONLY REMEDY.
