Hi, over time my blood pressure gauge (needle) is totally
off "zero". There is no indication in the manuals on
calibration. It was an expensive one top quality - I've
heard others have similar problems.

my suggestion would be to take it with you on your next
doctor's appt...or..if you are comfortable ..simply locate
the nearest office and appear at their front desk with a
humble "could you please check this for me??"

most such places will accommodate you...

remembering that it is not just re zeroing it ..which can
work for a bathroom scale..but comparing the readings to at
least one other machine..better still more than one..

another idea..if you can find a time when your local ER is
not swamped..I bet they would help you...

last idea...call the manufacturer..

good luck

hawki.....

I don't know if you can calibrate this. You should call the
makers of the blood pressure cuff and ask them.

Is it possible to calibrate?! I've tried moving the needle
back to zero with a magnet and also by tapping slightly,
neither worked.

Also inspecting different products none seem to mention
ability to calibrate? I have been mentally calibrating
(subtracting).

TIA

Take it to Walmart and take your blood pressure with their
machine (near pharmacy window). Then compare their machine
reading to yours.

I wouldn't think that's the best idea, though it may be OK
as a start.

I'd imagine that calibrating against a human expert reading
from a full-size mercury-filled meter would be best.
(mercury as the resistance depends on more immutable laws
of physics and not a spring whose springiness can change
over time.)
