Other possible errors and their solutions
If problems occur when using this device, the following points should be checked.
NOTE:
Blood pressure is subject to fluctuations even in healthy people.
Please remember that
comparable blood pressure measurements always require the same time and the same
conditions!
These are normally quiet conditions. If you follow the procedure described earlier and still get
fluctuations of blood pressure of greater than 15 mmHg and/or you repeatedly hear irregular pulse tones,
consult your doctor.
Attention!
Should any technical malfunctions arise in the blood pressure monitor, please contact the dealer where you
bought the device or ADC.
Never attempt to repair the instrument yourself!
Any unauthorized
Error No.
ERR 1
ERR 2
ERR 3
Possible Cause(s)/Solutions
Pulse could not be detected. Please ensure the cuff is properly
placed on the inside of your wrist and repeat the measurement.
Unnatural pressure impulses influence the measurement
result. Reason: the arm was moved during the measurement.
If inflation of the cuff takes too long, the cuff is not correctly
seated. Reposition the cuff and repeat the measurement.
ERR 5
HI
LO
The difference between systolic and diastolic is excessive.
Measure again carefully following proper procedures. Consult
your doctor if you still get unusual results of measurements.
The pressure in the cuff is too high (over 300mmHg). Relax for
5 minutes and repeat the measurement.
The pulse is too low (less than 40 beats per minute). Relax for
5 minutes and repeat the measurement.
Malfunction
The display remains blank when
the device is switched on though
the batteries are in place.
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.
1. Fit the cuff correctly on the wrist.
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.
