How do I know if the device is still accurate after long usage or after being dropped?

Generally, the monitor gives accurate results if it is working. If, for example, the device has been dropped but you cannot detect any malfunction when operating it, there is no need to worry about the accuracy. The main component that mainly influences the accuracy is stored in the computer program. This software either works or doesn’t. Other parts which affect the accuracy such as the deflation valve and the pressure sensor are very well protected against modifications by accidents or ageing.

In any case and in accordance with international standards we recommend that you ask your authorised Microlife dealer to perform an accuracy check every two years.
