We purchased the UA-767F blood pressure machine. we have had it for about 2 months. We use it daily, since my wife had an Aortic replacement. we recently took it to Mayo Clinic to have it tested. they said the SYS was accurate, but the DIA was too low by 5 , usually, and once too low by 10. Is there a way to get it calibrated

Question: how was your machine tested? Do you mean that they compared it to a manual reading taken on your wife, or that they hooked your machine to a simulator (test equipment) and compared those numbers?
