Malfunction / Troubleshooting - Microlife BP AG1-20 Instruction Manual

5. Malfunction / Troubleshooting

If problems occur when using the device, the following points should be checked and if
necessary, the corresponding measures are to be taken:
Malfunction
The sound transmission is
poor, distorted or there is
extraneous noise.
The pressure does not rise
although the bulb is pumping.
The deflation rate can not be
set to 2-3 mmHg/ sec. by
adjusting the air release valve.
Pointer is not at 0 +/- 3 mmHg
at rest.
☞ Further information
The level of blood pressure is subject to fluctuations even with healthy people. Important thereby
is, that comparable measurements always require the same conditions (rest condition)!
If, in spite of observing all these factors, the fluctuations are more than 15 mmHg, and/or you
hear irregular pulses on several occasions, please consult your doctor.
You must consult your specialist dealer or chemist if there are technical problems with the blood
pressure instrument. Never attempt to repair the instrument yourself!
Any unauthorised opening of the instrument invalidates all guarantee claims!
Remedy
1. Check the ear pieces if they are plugged or cracked. If not,
make sure they do not fit poorly as worn.
2. Check the tube if it is broken or twisted.
3. Check the bell and diaphragm of chest piece if there is any crack.
4. Make sure the chest piece is in proper contact with skin and
over brachial artery during measuring. Clean or replace any
defective parts if found to avoid inaccurate reading.
1. Make sure that the valve is closed.
2. Make sure the cuff is properly connected to bulb and manometer.
3. Check if the cuff, tube and bulb is leaky. Replace the defective
parts if any.
• Disassemble the valve from bulb to check if there is any
blockage in the airway of the valve. Clean the blockage and
try again. If it still does not work, replace it to avoid inaccurate
reading.
1. Make sure that the valve is open for zero check.
2. If still more than 3 mmHg deviation, contact your dealer to
recalibrate the manometer.
