24.4 Pressure Accuracy Verification
Pressure Accuracy Verification is a function to inspect the accuracy of pressure measurement by the NIBP module inside
the device. Technician or equipment manager should do pressure accuracy verification every half year or year in order to
check if the pressure measurement still conforms to the requirement of product performance. If the deviation is beyond
the declared specification, it is permitted to return it to factory for repair or calibration.
Before verification, please connect the monitor to a precision pressure meter as the reference equipment like a mercury
pressure meter
Mode 1: Automatic inflation for the pressure accuracy verification
At this mode, the monitor can activate the inflation, so the pressure will increase automatically until it exceeds the limit
value specified in table A. This pressure limit value depends on the patient type selection as shown in table A:
Adult
240mmHg
Pediatric
200mmHg
Neonate
120mmHg
Table A
During the inflation, the Monitor will close the deflating valve, and the pressure value will be shown during the process.
If there is no manual deflation operation, the pressure will persist until deflation by manual operation, so it is necessary
to use a manual valve for doing adequate deflation in several steps to verify the pressure accuracy in the full scale of
measurement range.
