It is easy to use APT for your service needs. Before returning your instrument you will need to receive an RMA (Return Materials Authorization) number from our customer support department. This allows us to expedite the processing of your instrument.

You can contact us for an RMA number at 1-877-322-7693. In order to provide an RMA number we will need the model number and the serial number of any instrument you wish to return. We will also need a shipping address to return your instrument and a billing address for all relevant invoicing. When packaging your instrument for return please clearly mark the RMA number on the outside of the box. It is also a good idea to include the RMA number on the packaging list. This will again help expedite processing. Please make sure that each instrument is packaged securely in its own box. If possible you can use the box that was used for original shipment.
