To send a product to us for repair, service or recalibration, you must first obtain a Return Material Authorization Number (RMA#) using the steps below. Please do not ship any products until we provide you with an RMA#.
Shipments will not be accepted without an RMA#.
Contact us using one of the following methods, providing as much detail as possible:
- Via the Calibration Request Form on this page (this is the preferred method)
- Via Phone: +1 800-274-8888 (toll-free, USA and Canada only) or +1 516-333-4840 (toll)
Your request will be processed and an RMA# will be issued to you via e-mail along with instructions for returning the item(s) for calibration.
NOTES: Calibration Charges: You will receive a quote for calibration at the time an RMA number is issued.
Standard recalibration intervals are 1 year. Please specify if a 6 month interval is desired. The only exceptions are the DM-365X, DM-254X/DM-254XA, DM-450X/DM-450XA, and DSE-2000 meters, which have a 6 month recalibration interval, unless a 1 year interval is requested.
Please complete the fields below as specifically as possible. This will help to ensure the fastest and most accurate response possible.
