"I need the calibration certificate or a duplicate calibration certificate."
In order to help and if not already provided, we'll need the following information to generate duplicate certificates:
The model name and number
The order number (if available) or the name or the email it was purchased under
The serial number(s) of your device(s)
Date (or approximate date) of purchase
The email where you'd like the soft-copy duplicates sent
Once submitted, it can take up to 2 weeks to process requests and send duplicates.
