Possible cause(s) / Solutions
The tube may have loosened, or no pulse was detected. *En-
sure cuff connections are tight with proper cuff placement. See
Section 5.3
Unnatural pressure impulses. Reason: The arm was moved
during the measurement. Repeat measurement keeping arm still.
Repeat measurement keeping arm still. If inflation of the cuff
takes too long, the cuff is not correctly seated or the tube con-
nection’s not tight.
Check connections and repeat.
The difference between systolic and diastolic is excessive.
Measure again carefully following proper cuff procedures and
ensure measurement under quiet conditions.
The cuff pressure is too high. Relax for 5 minutes and repeat
the measurement.*
The pulse is too low (less than 40). Repeat the measurement.*
*If this or any other problem occurs repeatedly, please consult your doctor.
Other possible errors and their solutions
If problems occur when using the device, the following points should be checked:
Malfunction
The display remains blank when the instru-
ment is switched on although 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.
Remedy
Check battery installation or AC adapter connec-•
tion is correct and wall outlet is working.
If the display is blank, remove the batteries and•
then exchange them for new ones. Check polarity.
Check the connection of the cuff tube and connect•
properly.
Ensure the cuff fits properly. (Section 5.3)•
Before starting measurement make sure that the cuff•
is not too tight and 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.
