The measurement results are displayed.

•  Once measurement is complete, the 

cuff deflates and the measurement 
results (systolic/diastolic blood pressure 
values, pulse) are displayed.
*  Systolic/diastolic blood pressure values 

and pulse are displayed alternately.

*  Provided there is no error in the measurement 

results, they are stored automatically.

Finishing measurement.

Hypertension Classification lndicator 

•  Press the “  START/STOP” switch to turn the monitor off.
•  After taking the blood pressure measurement, pressing the “  START/STOP” 

switch will turn the monitor off. However, if you do not press the switch, the 
monitor’s Auto OFF function will automatically turn the monitor off after 1 minute.

Irregular Heartbeat Indicator

If an irregular heartbeat is detected during measurement, the Irregular 
Heartbeat (IHB) Indicator is displayed after measurement is completed.

There are 2 conditions under which the signal of IHB will be displayed:
1) The coefficient of variation (CV) of pulse period > 25%
2)  The difference of adjacent pulse period   0.14s, and the number of such 

pulse takes more than 53 percentage of the total number of pulse.

•   Measurement may not be correct if your heartbeat fluctuates greatly during measurement. 

If the Irregular Heartbeat (IHB) Indicator is displayed, measure your blood pressure again.

Caution

If the Irregular Heartbeat (IHB) Indicator appears frequently, you 
are advised to consult a doctor about your health condition.
