I monitored regularly at interval of six hours for few days.I was surprised to see the varying figures vastly for

Change in position,in bed or chair
Evening and early morning
At Publix or CVS at the same time
At doctor's office by nurse and by doctor himself
When it is cold (say 52*F) and when hot (say 75*F)
Immediately after and before some work in garden.
With shirt sleeve on and off
Changing RT and LT hands

I wonder how can I believe measurements of BP !

Actually that is good. Blood pressure needs to change to meet the demand of the body. For example when standing more pressure is need to get blood to the brain then when laying down.

The standard requires you to be setting in a chair with a back and your feet on the floor. And that the being tested should be at heart level. And you should be quiet for 5 minutes.

Note that a difference in BP between the arm can indicate a health problem. See

Many body functions change during the day and BP is one of them. On the average it should be higher in the morning then in the evening.

The best way to monitor you BP is to take it at the same time once in the morning and once at night and keep track of it.
