I’m never sure if it’s me or the machine that’s failed (actually – it’s me) but I don’t want to find out that I’m slightly dead if the machine is working just fine, so generally I’ll re-take the readings.
Fortunately, it’s a known issue and the recommended workaround is just to take the reading again. It turned out fine, I’m no more dead than I am most other days.
What a relief!
