20–255 mmHg (2.7–34.0 kPa)
40–240 BPM
±5 mmHg (0.7 kPa) with a standard deviation no greater than 8 mmHg (1.1 kPa)
±2 BPM or ±2 % (whichever is greater)
Initial inflation to 160 mmHg (21.3 kPa). Subsequent inflation approximately 30 mmHg
(4.0 kPa) greater than the previous systolic pressure.
Automatic
Automatic cuff deflation if: cuff pressure exceeds the overpressure limit of 285 ± 15
mmHg (37.3 ± 2 kPa); or maximum reading determination time is exceeded (not to
exceed AAMI /ANSI SP10-1992 limit of 180 s); or safety timer detects microprocessor
failure. Auto mode minimum 30-second delay from the end of one determination to the
beginning of another to allow for venous return.
Systolic, diastolic, and mean pressure; pulse rate
Alternating 1.5 second chimes (773 Hz and 523 Hz)
Flashing pressure numeric or message
User-selectable high and low systolic, diastolic, and mean pressures;
User-selectable high and low pulse rate
Cuff errors, connection errors, insufficient signal, excessive inflation or determination
times, overpressure, hose errors, excessive motion, communication problem, or
self-test failure.
The 120 Series’ blood pressure module complies with the American National Standard for
Electronic or Automated Sphygmomanometers [AAMI/ANSI SP10-1992]. Blood pressure
measurements determined with this device are equivalent to those obtained by a trained
observer using the cuff/stethoscope method, within the limits prescribed by the American
National Standard for Electronic or Automated Sphygmomanometers.

Reproducibility is 1 standard deviation = 6%. Nominally, 68% of the measurements across
the population will be within ±1 standard deviation.
