connected to an NIBP simulator or a Rigid cuff can as a closed reference volume. For
the detailed test procedures in this mode, refer to the Performance Test section.

stop the test during test progressing, press the knob.
Note: If any further NIBP test is not selected to be performed after a test is completed, a
