Yuwell YE660F - Common Fault and Trouble Shooting

5. Blood pressure variations?
An individual's blood pressure varies greatly on a
daily and seasonal basis. It may vary by 30 to 50
mmHg due to various conditions during the day. In
hypertensive individuals variations are even more
pronounced. Normally, the blood pressure rises
while at work or play and falls to its lowest levels
during sleep. So do not be overly concerned by
the results of one measurement. Take
measurements at the same time every day using
the procedure described in this manual to get to
know your normal blood pressure. Regular
readings give a more comprehensive blood
pressure history. Be sure to note date and time
when recording your blood pressure. Consult
doctor to interpret the blood pressure data.
6. When is the best time to measure blood
pressure?
After urination, before breakfast in the morning.
Before sleeping at night.
Before taking medicine.
Please keep a stable body state and mind every
time measuring. We suggest taking
measurements at the same time every day.
