to be displayed in subsequent readings, we recommend
you to consult your physician in order to determine if it is
cause for concern. Do not try to interpret readings or at-
tempt to treat any condition yourself. Always follow the
guidance of a health professional. If you have an emer-

7.2 Joint National Committee (JNC) classification
WARNING:
• The JNC chart is not intended to replace a medical
diagnosis. This chart is only a reference for different
classifications of blood pressure.
According to JNC Guidelines/Definitions and the latest find-
ings, the test results of adults can be classified and evalu-
ated according to the following chart:
Stages of blood pressure levels
Stage 2 Hypertension
Stage 1 Hypertension
Pre-hypertension
Normal
Source: U.S. Department of Health and Human Service, JNC7 (2004), adapted
NOTE:
This standard, however, is a general guideline as an in-
dividual's blood pressure varies among different people,
age groups, etc. Please consult your physician for proper
diagnosis.
The bar graph in the display and the scale on the unit indicate
the range of the blood pressure which has been recorded.
NOTE:
If the values for systolic and diastolic pressure are in two
different JNC ranges (e.g. systolic in the high-normal range
and diastolic pressure in the normal range) the graphic JNC
classification on the unit indicates the higher range (high-
normal in the example described).
