4.4 REPAIR
METER repairs manufacturer defects and instruments within the 1-year warranty at no
charge. Repairs outside of the warranty window are charged based on cost of parts, labor,
and shipping. An extra fee may be charged for rush work. Contact Customer Support for an
estimated repair cost.
METER has loaner instruments available for a fee while the WP4C is being serviced.
All WP4C units returning to METER for servicing must be accompanied with a Return
Merchandise Authorization (RMA) number. Prior to shipping the instrument, contact
Customer Support to obtain an RMA number.
The following steps will help to ensure the safe shipping and processing of the WP4C:
1. Ship the WP4C in its original cardboard box with suspension packaging.
If this is not possible, use a box with adequate space (at least 4 in) between the
instrument and each wall of the box.
2. Place the WP4C in a plastic bag to avoid disfiguring marks from the packaging.
3. Do not ship the power cord, serial cable, or any other accessories.
