Unrecoverable System Errors
Certain system errors could result in abnormal operation
of the BpTRU, which could present a hazard to the
operator or patient. To prevent such a hazard, the
BpTRU monitors the following functions and
parameters.
1. Proper internal voltage supply.
2. Proper functioning of the microcontroller.
3. Over-inflation of the cuff (maximum 330 mmHg).
4. Overtime inflation of the cuff (over 10 mmHg for
maximum 3 minutes).
If any of the above conditions occur, the BpTRU will
perform the following actions:
1. Deflate the cuff.
2. Sound a five-second alarm tone to signify that a
unrecoverable system error has occurred.
3. Deactivate the main display and display the device
malfunction indicator ( ).
To resume normal operation, turn the power off and
then back on again.
If normal operation does not resume, contact your
distributor or BpTRU Customer Support.
