If the result from the deflation speed test is
below the limit, check that the cuff hose is
correctly connected to the cuff and that the tube
is not kinked or squeezed.
Otherwise the failure is caused by the BPM
module and it must be replaced and sent to
Gambro for repair.
If the result from the pressure transducer cali-
bration test is outside the limits, it indicates that
the self-calibration function within the BPM
module not is able to adjust the pressure trans-
ducer output within limits. Possible causes are
pressure transducer or electronic circuits mal-
function. The BPM module must then be re-
placed and sent to Gambro for repair.
