Welch Allyn Connex Spot Monitor Directions For Use Manual page 67

Directions for use
The monitor uses the oscillometric method to determine blood pressure; therefore, if the
cuff extends to the antecubital fossa (bend in the elbow), you can still acquire an
accurate blood pressure reading.
If you use a single tube NIBP cuff, you can take only a step blood pressure
measurement. The monitor will automatically default to Step BP.
CAUTION Correct sizing of the blood pressure cuff is important for
accurate blood pressure readings. A cuff that is too small might provide
false high readings, while a cuff that is too large might provide false low
readings.
