Possible cause
●
The position of the cuff is higher or lower than your
heart when measuring.
●
Cuff is not wrapped correctly.
●
You moved or talked during measurements. (See
page9.)
● Blood pressure varies in response to minute changes
in your mental state, such as your reaction to a doctor's
presence.
●
Sit quietly for 4 to 5 minutes and then take another
measurement. (See page17.)
●
Batteries are installed with the polarities wrong. (See
page6.)
●
Batteries are exhausted. (See page6.)
There was a significant fluctuation in pulse when readings
were being taken. (See pages 11–12.)
Your arm or body moved or the buttons are pressed
during the measurement. (See page11.)
In some cases this will be displayed when you have tensed
the muscles in your hand. Relax the muscles in your hand
and take the reading again. (See page11.)
Take it to the store where it was purchased for testing and
repairs.
