Blood pressure monitors and how to use them; taking a blood pressure measurement; continuous monitoring

[Sly Saint]

@mango have you or others found a different home blood pressure monitor that works better? My Omron gives me the E5 (pulse not detected) error when standing (and sometimes seated). Omron customer service essentially told me it's not their problem because you're only supposed to use them seated on a hard surface. They suggested I take my BP manually (not something I know how to do and not convenient to do 3 times in a row for orthostatic vitals). Thanks!

I use an A&D Medical BP monitor that I bought, as this was the same as the one my GPs surgery loaned me to begin with.
I've used it to take it standing, sitting, lying down.
