Other possible errors and their solutions
If problems occur when using this device, the following points should be
checked.
Malfunction
The display remains blank when
the device is switched on though
the batteries are in place.
The pressure does not rise
although the pump is running.
The device frequently fails to
measure, or the values
measured are too low or high.
Every measurement results in
different values, although the
device functions normally and
normal values are displayed.
Blood pressure values differ from
those measured at the doctor’s.
Remedy
1. Check battery installation/ polarity.
2. Remove the batteries and if the display is
unusual, then exchange them for new ones.
Check the connection of the cuff tube and
connect properly.
1. Fit the cuff correctly on the arm.
2. Before starting measurement make sure that
clothing is not exerting pressure on the arm. Take
articles of clothing off if necessary. Measure blood
pressure again in complete peace and quiet.
