Frequently Asked Questions
I have set the pressure to the correct level, but when I take my reading all that is displayed is ERR or ERR2. What am I doing wrong?
Although you may be sitting correctly, and have the pressure setting on the appropriate level, you must remain very still. The blood pressure monitor works by sensing vibration of blood as it moves under the cuff. Moving, talking and other causes of vibration may result in an error message. The symbols ERR or ERR2 mean that either you or the monitor moved during the reading.
