How can I test the accuracy of my aneroid manometer?

The only way to be 100% sure is to connect the manometer in series to an instrument of known accuracy and test during deflation at a variety of pressures (i.e. 300, 260, 180, 120, 60, etc.) When testing your sphygmomanometer, it is important that you check the accuracy in accordance with national or international standards that may be applicable to your device. For devices manufactured and sold within the US, the European Union and other international destinations, the ANSI/AAMI/ISO 81060 standard entitled Non-invasive sphygmomanometers — Part 1: Requirements and test methods for non-automated measurement type is applicable.
